Illinois Architect-Homeowner Built With Warmboard in 2002

In this installment of Warmboard Works, we talk to Jim L. from O’Fallon, Illinois, who back in 2002 was one of the first in the state to design and build his home with Warmboard. His family is downsizing and selling the property and Jim has been kind enough to detail what the past 17 years have been like living with the incomparable comfort of Warmboard. Jim is a licensed architect in Illinois and Missouri and is currently the coordinator of a Construction Management Technology Program at a local college.

 “I designed the home with our young family in mind and would characterize the style as a “city house” located in O’Fallon, IL – the first Warmboard project in the St. Louis metro area. Our house is constructed with 2x6 exterior walls at 16” o.c. with a “BIB” insulation system. The attic has approximately 24” of the good white fluffy stuff (no energy trusses) and we used R10 rigid board under our basement slab. The basement slab has 3 heat zones, the Warmboard first floor has 3 heat zones, and our second floor uses fin tube base units in each of the bedrooms with separate zones. The boiler is 83% efficient.

When we built in 2002, our children were young and our oldest had asthma really bad. I was looking for ways to improve our indoor air quality for our kid’s health. Robert Meyer, a mechanical engineer I had worked with in the past, recommended Warmboard to us. I recall him saying “there is a new product available that would bring a higher level of quality with positive health benefits to your home”. He was anxious to work with Warmboard as he hadn’t used it in the past.

We moved into the house in January of 2003 and immediately noticed comfortable, even heat throughout the house, but especially the first floor where we used Warmboard. The house was absent of cold spots and my wife often told me how much she loves our home in the winter because of the even heat and the feeling of walking in from the outside as if she was walking into a down blanket. Structurally, when we upgraded to a high spin cycle washer, we didn’t have any issues with vibration in the floor system. We used 12” TJI’s at 16” o.c. so our floor system is substantial. There is absolutely no noticeable deflection or vibration. It’s so solid, it feels like you are walking in your Savings & Loan.

Our previous house used a gas-fired forced air system and had a leaky envelope. It was approximately 1,450 sq ft total including a finished attic. There really is no comparison between forced air heating and Warmboard radiant. The energy bills in our new house, which is over 3,200 sq ft, are very similar. So, we more than doubled our space and our energy bills stayed the same!

The finished floors we used were 3/4” tongue and groove 3” wide red oak and 3/8” cement board with ceramic tile over the Warmboard. We didn’t want any elevation change where materials transitioned so we installed the oak directly over Warmboard. We have never had a single issue and the floors are as beautiful as the day they were installed!

Our kids are grown up, healthy, and have moved on but frequently complain about college housing and the subpar comfort compared to our family home. What we will all miss the most is taking our shoes off and feeling that even heat in our house!”

NeverSummer Construction Series - Project Summary

This is the first post in a new Warmboard Works series we’re documenting with NeverSummer Construction from the Grand County area in Colorado. We’ll be checking in regularly to get updates on the project throughout the build and see the home come to life through interviews, photos, and videos. In this first installment we talk to Brad Line, co-owner of NeverSummer Construction, to learn more about the business, the project, and why Warmboard radiant heating was chosen to provide the ultimate home heating comfort.


Type: Single family home, new construction
Location: Granby, Colorado
Total Square Footage: 2,800 square feet
Lot Size: ¼ acre
Energy: Natural gas, Triangle tube boiler

How did the project come about?

My wife Makena, my brother Conrad, and I moved out to Granby, Colorado from our hometown in Ohio about a year ago, after purchasing Neversummer Construction from Hal Simmons, a respected, longtime custom home builder. My wife and I found a small condo to purchase and immediately began the planning process for our home. My dad, who is a retired engineer, is still very active in real estate ventures and had a set of plans that we fell in love with. He was about to build a home with a similar floor plan that had some slight variations and we thought it would be great to try out different products and do a comparison so we could show these differences to potential clients.


Conrad and I are committed to staying up to date with the newest means and methods that advance construction. We are always interested in learning about new products that streamline the installation process and create a more efficient and more comfortable home. We had both learned about Warmboard awhile back and had been following some other builders on Instagram who were using it. We were very interested in the product and decided it would be a perfect opportunity to try it out on our own home first to really understand how it works and then be able to share with our customers why we think it is a superior product.


 How would you describe the project?

Our home would fall into the mountain craftsman category; the exterior of the home yields a craftsman look with a great roof line while the interior gives way to tall ceilings, an open concept main living, and a mountain modern finish. We are building in a quaint development nestled in the heart of Grand County in Granby, Colorado giving us wonderful views and great access to all the different recreation opportunities located at either end of the county.


One of the reasons we choose to use Warmboard is because we are striving to build an energy efficient home for the long winters we experience here at 8,000+ elevation. We also use Huber Zip-R Sheeting on all our homes as it provides a continuous R6 level of insulation on the outside of the home. We will use an open cell spray foam on the lid and fiberglass batts on the walls. Due to how tight the home is we are also installing an air exchange system known as an ERV to make sure we maintain proper air exchange, so the home does not become a ‘sick home’ due to it being so tight. The home site is one of the flattest lots you could probably build on in Colorado and while that was not an issue, we had to over dig the foundation and add engineered fill as the soils were expansive. We chose to over-dig instead of putting in piers for a pier foundation as we felt it was not only more cost effective for us but provided a better product. 


Why was radiant chosen?

We believe that radiant floor heating is a superior method for heating the home. Coming from the Midwest we are used to using and working on homes with forced air systems due to the need for air conditioning in the summer, which is not a necessity for these mountain homes due to cooler temperatures through the year. Forced air systems are inefficient and leave much to be desired as they collect dust, are noisy, and do not provide the same comfort level as compared to radiant. Forced air heat rapidly rises to the ceiling compared to radiant heat which heats objects and people and doesn’t stratify upwards, so you are able to maintain a constant comfort level in your home with less energy output. For us it was the most efficient choice knowing it would serve us well through the life span of the house.  And who doesn’t love a warm floor when they get out of bed in the morning?!


Why was Warmboard chosen over other radiant technologies?

We chose Warmboard over other hydronic methods because of energy efficiency, temperature change responsiveness, zoning, and combining multiple parts of the installation process into one step. Warmboard has an aluminum coating on the top that helps to spread the heat evenly and directs it upwards making it more efficient. This also makes it much more responsive to adjustments on the thermostat as it doesn’t store heat like a traditional, old-fashioned radiant system. Anyone who has experienced traditional radiant homes knows that sometimes it can take a long time to feel a change if the room is getting too hot.


We really liked how Warmboard worked with our floor plan to create different zones in the home to maximize the comfort level. Warmboard also combines multiple parts of the installation process into one step by creating a product that serves as the subfloor and provides the grid for the tubing. This means we were able to install the aluminum pex tubing for the whole house with three people who had never installed it before in one day. It cut out the need to have the plumber install it underneath the floor joist or use gypsum concrete on top of the subfloor.


What is your previous experience with radiant heating?

Our experience building with radiant before left us with hot spots in the home as well as other cold spots due to the thickness of the thermal mass that the tubing had to heat through; i.e. subfloor or slab. There are also issues with installing hardwood floors or modifying a floor plan with old-fashioned, traditional radiant as you don’t know exactly where the tubing is which leaves room for mistakenly penetrating tubing with a nail and causing costly damages to the home.


How has your experience been with Warmboard thus far?

Excellent. The whole process from design to material delivery to install has been seamless. The literature on the product has made the learning curve much more manageable. The product came well packaged and there were no damages. All the tools and tips provided for the install made it go very easily; it took us one day to install all the tubing for a 2,800 sq. ft. home with three people! The quality of the manifolds and the tubing is exceptional and we have been impressed each step of the way.

Stay tuned for the next update on NeverSummer’s project and see how far along it has come. We can’t wait!


Sonoma, California Homeowner Thrilled with Warmboard since 2014

We came across this comment on a recent blog post by Sarah Sherman Samuel, Interior and Product Designer extraordinaire, and reached out to Elaine to learn more about what the last 5 years have been like living in her Warmboard home.

“We chose Warmboard after doing extensive market research on other radiant floor heating systems. Warmboard made the most sense to us in terms of quality, durability, and simply a smarter system.

We built this home ourselves with Warmboard and used travertine tile for all the floor coverings. 

There are many benefits that we appreciate about our Warmboard floor such as even, consistent heating, no matter the time of day. Our Warmboard system maintains the warmth of our home 24/7 without having to turn on/turn off, etc.  

Another aspect of our radiant heating system that we enjoy is that it is quiet. There are no vents to deal with and no air is being pushed around our home. It’s completely dustless! Warmboard is extremely comfortable and healthy heat!!!!!!!

And like I stated in my comment on Sarah’s blog, our children come to visit and don’t want to leave. Which I don’t really mind.”

Thanks to Elaine for sharing her family’s Warmboard experience with us and we wish them many more years of unequaled comfort!

Canadian Homeowner Reports Back on First Winter with Warmboard

In this installment of 
Warmboard Works, we talk to Remko T. from Ontario, Canada, who built his home in 2018 near the shores of magnificent Lake Erie. He’ll recount for us his experience building and living with Warmboard in his family’s 2,650 sq ft home and 1,100 sq ft detached garage.

“We chose Warmboard for our new home that we built last year and couldn’t be happier! We considered all the options available for floor heat and found that the extra panel cost for a Warmboard system was worth it. We were not disappointed! The panels arrived on time and the framers had no trouble putting it in following the layout plans. House construction can be tough on subfloors but Warmboard held up amazing!

I also waited on installing the pex tubing until the walls were up and the plumbing, wiring and exterior wall insulation was done. I did the custom router loops myself with the template kit provided. I ran all the pex lines according to the plans provided to the manifold locations just before the drywallers started.

We decided to keep it simple by making one heat zone for each the basement, the main floor, the top floor, and the detached garage. The hot water heater is another zone. We did not use slab sensors anywhere, just thermostats in each zone.

The boiler we chose is a 160,000 btu IBC Canadian-made boiler. It has 5 built-in zone controls and an outdoor reset thermostat as well. It’s a very simple and well-built boiler and incredibly easy to operate.

Overall, we are thrilled with our warm floors! Our Warmboard system heats the house very evenly and very comfortably. We are pleased with the fast response to both raise and lower the temperatures in the house as desired. I run the water temperature in the floor between 110°-125°F which gives us great response times and is lightning fast! I’ve also noticed the heating keeps up easily when it is below 0°C outside. During the day we typically keep it at 19°- 21°C and at night we set it down to 17°C.

The cost to heat the house to 19°C and the garage to 15°C is on average $300-350 per month with propane @65cent per liter. This is a bit disappointing but I’m anticipating the cost will decrease at least 33-50% when natural gas comes through in the near future.

My wife and I love our Warmboard home and we can’t help but notice the lack of radiant heating and lack of Warmboard’s invisible comfort when we go to anyone else’s house.”

Longtime Happy Homeowner - Alex Z. in Pennsylvania

In this Warmboard Works, we hear from Alex Z. in Pennsylvania, who built his house back in 2005 using Warmboard and has never looked back. He is graciously sharing his experience living in a 3,700 sq ft Warmboard home for over a decade and will explain the main reasons why he selected a Warmboard radiant heating system.

“I’ve been a Warmboard customer for nearly 15 years now and I am an extremely happy customer!!!

When I bought my house, I knew it was a total rebuild. I spent many months researching and designing my new home, carefully selecting all of the products that went into the build. I chose Warmboard for a few reasons (not in any particular order):

1) The rebuild meant I had to replace nearly 4000 sq ft of subfloor and I wanted to put in radiant heat. Without Warmboard, I could not have afforded to do both! The incremental cost (at the time) was 15% higher than just a standard subfloor but I got both radiant heat and my subfloor at once!  It also sped up the build time, which was very important.

2) My house was designed at about 4000 sq ft, however, there is A LOT of volume in my house. Most of the ceilings are roughly 14 feet high. No other method of heat, other than radiant, was going to give me the comfort I wanted. With Warmboard I also got equal heat distribution across the entire floor…there are no warm/cold spots, especially near the edge of the house (exterior walls).

3) What I was surprised at after the fact was the efficiency! I have a very small boiler for my house size (it’s 80k BTU’s for both domestic hot water and heat!) yet I get heat from the floor in about 30 minutes. Additionally, my heating costs are extremely low. By running the water through the floor at 110 degrees my heating costs are about $150-170/month. Conversely, my AC bills are always over $500/month in the summer!!!

I can’t directly compare my current heating costs to my pre-Warmboard heating costs as we went from oil heat/radiators to Warmboard, powered by natural gas. The home also increased in size from 1,380 sq ft to 3,700 sq ft. 

I value the comfort my Warmboard radiant heating system gives me and have been thrilled with the phenomenal performance all these years. I anticipate another 15 years of enjoyment and satisfaction!”

Streamline Design Ltd, British Columbia

Kevin Simoes of Streamline Design Ltd tells of his first experience using Warmboard. The Gabriola project is a post-and-beam home in British Columbia and features over 3000 square feet of Warmboard-R.

“We chose Warmboard for its ease and its convenience. The structure was built on an island, so we knew the construction costs were going to be high. Costs for using concrete for the radiant heating were especially high, so we knew that would not be a viable option. In fact, Warmboard was the cheaper option and definitely had a positive impact on the budget. Combined with its performance claims, Warmboard became the natural choice.

Working with the Warmboard has been a great experience. The design team was fantastic. They were responsive and easy to work with. They answered our questions promptly and produced working drawings very quickly. And while we provided only the architectural design (we were not the installers), the feedback from the contractor was very positive as well. The installation drawings provided were very helpful and easy to follow, and they were pleased with how quickly and easily [the panels] went down. The ease and speed of the installation was actually one of the great benefits with Warmboard. It definitely made an impression.

The homeowner was very pleased with the install and subsequent system performance as well. They have also remarked that they have really noticed the savings on heating costs.

Overall, we have had an incredible experience work with Warmboard. The team is very professional, easy to work with and always happy to help educate architects, installers and the clients. And you have a great product! The team at Streamline has been very pleased to team up with Warmboard on additional projects and we look forward to specifying the product on many jobs in the future.”

Sustainable Edge, Toronto

In this Warmboard Works we hear from Mario Kani of Sustainable Edge, an Engineering firm in Toronto, Ontario.

For over a decade we have been using hydronic radiant heating and cooling in ceilings. The benefits of a fully hydronic house with moderate heating and cooling water temperatures and no recirculated forced air are many, including: 

  • Complements low energy envelopes which require lower heating and cooling capacities
  • Provides better comfort
  • Delivers healthy indoor air
  • Promotes minimum noise in living spaces
  • Requires minimal and smaller ductwork (ventilation only)
  • Results in lower distribution energy (by using a pump instead of a fan)
  • Increased flexibility for thermal supply source such as solar or geothermal energy

Locating the radiant cooling on the ceiling provides the maximum output for a specified design surface temperature. While we have designed several projects using concrete radiant ceilings, we have found that for wood construction, Warmboard is a natural match for ceiling installation, placed just behind the drywall. Warmboard is also an ideal candidate for radiant heating in the ceiling as well, able to provide either low- or high-intensity heating during winter months.

The principle of ceiling cooling is based on average surface temperatures between 60ºF to 70ºF over a large surface area, resulting in draft-free, low-intensity cooling. The cooling surface temperature needs to be high to avoid surface condensation. This system only does sensible cooling of the living space (i.e. no moisture removal) so that dehumidification needs to be done separately. For a successful ceiling cooling installation, the project’s attributes should be as follows: 

  • A high performance thermal envelope to minimize cooling loads through careful glazing selection and summer shading,
  • Significant envelope airtightness
  • 100% outdoor air ventilation without recirculation (also known as DOAS: dedicated outdoor air system )
  • Ventilation heat recovery (preferably an ERV)
  • Dehumidification of outdoor air with 45ºF to 50ºF chilled water (e.g. directly from ground water or via ground source heat pump) resulting in drier ventilation air than room air.

We look forward to using Warmboard–R, the thinner retrofit product in our next radiant ceiling project.

Homeowners Jeremy & Callie, Kansas City

In this Warmboard Works post we talk to Jeremy and Callie, homeowners who are in the midst of remodeling a 100 year old commercial building into their dream home. The West Bottoms Project is not your run of the mill remodel and these innovative DIY'ers are using Warmboard to bring ultimate comfort to this unique project. Bonus – they documented much of their construction in a photo essay, which can be found here:

“There are probably 400 reasons why we chose Warmboard, but I’m sure you’ve heard all of those before! I of course read a ton about the product and thought it would be an amazing luxury to have, but I figured it would actually be a bit too expensive – something I’m sure you guys hear all the time, right?

Our building is in the coolest neighborhood in Kansas City – called the West Bottoms – andwas originally built as a Horse Stable and Warehouse / Carriage House. It’s got a pretty interesting shape that comes from the railroad tracks that ran up to the loading dock doors on both the West and South walls (we have 7 loading down doors).

Because of the size of our building (the first floor is approx 6,000 sq ft), the 10 foot tall basement (also 6,000 sf ft) and the really high ceilings (about 25 feet in the main room), we knew heating the space adequately was going to get interesting.

The ceilings in our building are beautiful. 100 year old wood, amazing trusses and greatheight (probably too high, but whatever!). But having to hang duct work, seeing tubes everywhere would look like a mess and hide a lot of the charm of the building. It would have driven me crazy, and it would look hideous. So from an aesthetic standpoint it just wasn’t going to work.

Also, having hot air blowing down from our high ceilings, coming down to about 8 feet, then making a u-turn and heading back up towards the cold roof? No thanks. I had visions of us freezing on our couch with the roof being a toasty 80 degrees. So forced air wasn’t going to work on a functional level either.

Still, thinking our options were limited, we called in a slew of HVAC/Mechanical contractors. All came back with a horror stories of us needing multiple, monster heating and cooling units (that would go where? who knows.) to blow A LOT of air to POSSIBLY get us to a comfortable temperature. We then slogged through the data and crunched the numbers they gave us and the prices really skyrocketed. Suddenly, the thought of “Warmboard being too expensive” weren’t such an issue any more and it quickly became the best option to heat the building.

My wife Callie and I, along with some family and friends, have done 100% of the installation ourselves (We mostly pay our laborers in a combination of pizza, barbeque and gratefulness)! The plans you provided were amazing! As the project progressed however, there were a few issues with our structure we hadn’t really expected. But that’s the great thing about Warmboard–R – it was really easy for us to make adjustments on the fly, cut custom pieces or execute some custom routes to get around these situations. It’s one thing I really wasn’t expecting. This really is a great building tool! One that’s not meant to snap into place or it’s not going to work, but a panel that provides amazing flexibility in the design layout. The whole process was very intuitive. And anyone can easily grab 2 or 3 panels and carry them to where they need to go. We invested in 6 pairs of knee pads, 4 new drills and a TON of screws and it actually went fairly quickly, all things considered. Especially for a ragtag group like us. Moving forward, we will be hiring a professional to connect the boilers and the manifolds, run tests, etc. But as for all the panels, the tubing – we did all of it ourselves.

Callie and I are coordinating all the work on the job. It’s a monster project, but so far sogood. Things are moving forward quickly and we’re hoping to spend Thanksgiving there this year – just in time for the 100th birthday of the structure. We’ll have everyone there too and are looking forward to being really toasty!”

DG Custom Built Homes & Remodeling, LLC., NEW YORK

“DG Custom Built Homes & Remodeling recommends Warmboard as our first choice for radiant heat. Installed properly, radiant heat only uses energy when and where it’s needed. We like to zone each room individually; which saves money and eliminates having cool and hot spots develop as each part of the home heats and cools differently throughout the day. Warmboard goes in during framing and acts as a subfloor so there are no additional steps needed as with other products. Warmboard has a great support system from design to installation. The design team takes all the guesswork out of material to purchase and layout in the field. In addition to providing with a complete material list, their local rep stops by our job sites to ensure the installation is going smoothly.

As the owner of DG Custom Built Homes and Remodeling, I personally have built my home using Warmboard as the only source of heat. My home never feels cold or overheated. I spend 1/3 of what I used to spend on my previous home which was much smaller.Warmboard would be my first choice every time.”

Dorgan & Zuck Contractors, PENNSYLVANIA

Dorgan & Zuck Contractors has been in business for 31 years and is experienced with many types of construction projects. We have encountered many suppliers, sub-contractors, and products; some standard and some brand new and untested.

For various reasons we had never been able to work with Warmboard products before. An architect out of Manhattan, New York who was a C.M. on a multimillion dollar restoration project where we were the G.C., recommended Warmboard products for the various floors in an Historic farmhouse. The client had made his mark in the world by having a very high standard and uncompromising view. This necessitated a need on our part to have a support team and product that could provide the information, design, efficiency, and ease of use to satisfy these demands. [Your Sales staff] and Warmboard products met and exceeded those requirements. The floors were of various natural wood, tile, and granite, and all experienced great results.

Warmboard and their staff were accessible, informative, and adaptable and in the end, helped make us successful in that area of need. We are glad to have worked with Warmboard and hope to use [Warmboard] in other projects.

Helios Roofing, Helios Construction, BRITISH Columbia

In this Warmboard Works we hear from Louis Lu of Helios Roofing in Burnaby, British Columbia.

“The existing house has 2 stories and 50 years old. The previous heating system used forced-air heat, and the ducting was claiming a lot of space, especially in the attic. The owner wanted to increase the available space inside the house, but were not able to change its physical size of the structure. The homeowner was considering radiant heating as an option.

We had the architect and interior designer to do some research on radiant heating, and they foundWarmboard. The architect recommended Warmboard-S because it could be used as the subfloor and the control systems would take up a minimal amount of space. The homeowner agreed and the project began.

We gutted the entire interior of the house and rebuilt with LVL beams (and Warmboard) to create open spaces throughout. We completely transformed an traditional single-family house into a modern smart home, with all the latest technology built inside.

Along with Helios Homes and Contracting Ltd., we redid the structural, the framing, the roof, insulation, drywall the landscaping and even the swimming pool. The house contains all new plumbing, heating, lighting and an array of smart entertainment features (alarms, 3D home movie theater, smartphone and touch screen home monitoring systems, retractable vacuum system, zoned background music via bluetooth, and a piano stage with wireless mini microphones inside) along with a cigar and wine cellar, gym, sauna and massage table, pool table and more. It is an incredible 6000 square foot home, and it is all covered with Warmboard.”

Coastal Construction Management, CONNECTICUT

We received a great letter from Michael Scarpa at Coastal Construction Management, LLC in Pawcatuck, Connecticut. It’s his first project with Warmboard, and things are off to a great start. We’ll be following up with him in the months ahead for an update.

"I had heard about Warmboard subflooring, but assumed it would be too cost prohibitive to use – until I sat down and did a price comparison to Quik Trak product. I was surprised to find that Warmboard was actually less expensive. The equalizer comes from the labor to install Warmboard. I pay my framing crew to install a subfloor, whether it’s a standard T&G or Warmboard, so there is no cost variance, or perhaps a small increase depending on the amount of custom routing required. But, using Warmboard, I don’t have to pay my plumbers to install a Quik Trak panel system at the rough-in stage of the project – which, at plumbing rates, can be very expensive and time consuming. This savings more than makes up for the added cost of the Warmboard panels. Installing the tubing is about equal, with a slight edge to Warmboard due to the 12” spacing compared to the 8” for Quik Trak (less tubing equals less labor). All this said, it’s really the performance that is going to blow the competition away.

This is our first project using Warmboard so I’m really eager to hear the client’s comments on comfort and feel. I’m confident they’ll be impressed.

All of my dealings with Warmboard so far have been nothing short of impressive.

Geo Source One, Ohio

In this Warmboard Works, Jeff Persons of Geo Source One Inc. talks to us about his renovation of the “Rock House”. Located on property obtained through a land grant from the American Revolutionary War, the home was built while the area was still Indian Territory. Rather than tearing the home down, the structure was maintained and underwent an extensive renovation. The structure is entirely radiant heated and has a total of 8 zones to maximize comfort and control.

“We are geothermal systems contractors, and geothermal equipment is a perfect match for Warmboard. We’re strictly low temperature hydronics folks here, we don’t get into a lot of high temperature type situations. Because we’re working with high-efficiency condensing boilers and so forth, it’s important to keep those temperatures as low as possible.

Warmboard has been excellent to work with. It is the very best way to utilize geothermal equipment for managing a radiant floor particularly when you’ve got wood frame construction.

Also, just the ease of tubing installation in a Warmboard project. I like being able to use the linoleum roller to press the tubes into the channel and follow things around; and it’s not difficult to route new channels to get from one area to another.  The whole ease of working with the product really stands out to me, not to mention your team has always been excellent.  I credit you folks with your patience with homeowners and architects that make changes and then the drawings have to be repeatedly changed. In some instances we’ll have revision 1, revision 2, revision 3, and every time it comes back and its perfect.


This is not our first rodeo with Warmboard; we’ve had others, all of them excellent. I’m about to make a trip back to Ohio to finish off another project that used Warmboard in several areas. I’m looking forward to that visit and getting that project off of our books to make room for the next [Warmboard] one.”

vivZ architects, EDMONTON

In this Warmboard Works we hear from Vivian Zhao of vivZ architects in Edmonton, Alberta. In 2015, Vivian used Warmboard in a 12 unit condominium unit in Edmonton. Here’s what she had to say about her experience with Warmboard.

Grovenor Condominiums. Edmonton, Alberta

Grovenor Condominiums. Edmonton, Alberta

“With this project we used to 2 lots and combined together. The result is 12 townhouse units with a shared basement and underground parking.

We wanted to use infloor heating from the very beginning. One of the managers on the project had heard of Warmboard (but not used it), and thought it might be a good option, allowing for much faster installation, especially compared to the alternative, gypsum concrete.

So I started to look into Warmboard. And aside from the benefits of having a faster installation, there were many other benefits as well. You can use a much wider variety of floor finishing materials. I read through all of your online material and contacted your sales rep in Vancouver. I then flew out to Vancouver with my husband, and we met with your sales rep who showed us a couple of active Warmboard jobs in the area. It was very helpful to go on site and see the Warmboard still exposed. And we were able to see the control systems as well. This was very helpful. At that time I felt it would be the right product for our project. I began working with your design team in California, and soon after we were making payment and coordinating the shipping.

Working with design team was good. The team was very cooperative in designing the system efficiently as to keep costs under control. They were very helpful.

Much of the construction took place during the winter. So we put the panels in put could not yet put in the tubing because of the freezing temperatures in Edmonton. It’s just not possible. We did cover the panels a couple of times during the construction process with Rahm board, first during the winter and again in the summer after the tubing was in. This did cause additional labor for us, and it was time consuming. We would have loved to be able to rent cover panels from you as a temporary covering. Obviously in a smaller house, this wouldn’t be a big deal, but on a large multi-res project like ours, we think this would be a good thing to offer in the future.

This occupants of the building have been living with Warmboard now for 2 full heating seasons, and I can tell you the performance works very well. It is very satisfying. Our residents are amazed and how comfortable it is. And our gas bill is very, very low. Warmboard is saving us a lot of energy for sure.

I would definitely recommend Warmboard in the future and hope to use it in more projects.

JC Heating and Cooling, ILLINOIS

For this Warmboard Works we spoke with Jerry Chwierut of JC Heating and Cooling in Hodgkins, Illinois.   

"There are many aspects to look at when choosing the right product for our clients. Our company’s success comes from quick response and reaction time to our customers needs as well as our own fulfillment and productivity. The Warmboard company and products were very much in line with ours. Working with Warmboard has been a great experience. They offer great pricing along with a high quality product.   

Warmboard is affordable, but it is among the more expensive radiant heat systems. But this is due mainly to its general excellence of standard, especially with its thick aluminum.  One of our great experiences with Warmboard was the ease of installation process. Compared to Complete Radiant, it is unbelievably convenient, without any additional work input, where the other product requires extra labor in trimming or gluing with additional installations. Working with Warmboard cut down our working times allowing us to do a better quality job overall and to be more productive on the site.”

Our company is happy when our customers are satisfied. I would recommend Warmboard not only to our customers, but definitely to our own households and businesses which are looking for a good quality product of an upper grade. Warmboard, besides the aspects we have mentioned earlier, is a reliable radiant heating system with a smart design and energy efficiency. Our customers are satisfied with the decreased energy use, and we appreciate the quick installation time."

Pro-Star Mechanical, BRITISH Columbia

Wilf Scheuer of Pro-Star Mechanical talks to us about a unique build on top of a mountain on Gulf Island in British Columbia.

“We’ve been quite happy with our Warmboard experience, had no issues whatsoever. It was easy to work with, and we’ve done a number of Warmboard projects. I think we may have done the first Warmboard ever in BC and we recommend it highly.

Warmboard was a good product for this particular job because it’s on a remote access Gulf Island.  The project is on the top of a mountain above Mayne Island, so it’s quite cold up there as compared to being lower down. It took them five years to finish the job, but it’s a really beautiful architecturally designed home, the best views in the world I’ve ever seen. It overlooks the ocean, Active Pass, and the other islands.

So when talking to the client we gave different options and both the client and ourselves found that Warmboard was the best solution. The owner wanted a high quality system that was compatible with a geothermal heat pump because we drilled three holes 350 FT deep into the mountain.

With the combination of Warmboard, geothermal and the water furnace heat pump he’s got an excellent system that runs reliably and is economical. It’s economical to heat the home as compared to other fuel pipes in the Gulf Islands, which would normally be oil, propane or straight electric, so he’s probably saving 70% of heating costs as compared to traditional sources and it has really good performance.

We find that the heat is very, very even throughout the home and is quite satisfying. It has a lot of glass in there too so in homes with large amounts of glass it’s important to have good distribution systems for your radiant heat so that heat is applied evenly throughout the home so you’re not getting cold sitting by a window.


Overall, Warmboard seemed to be a really neat package that had good performance of heating; he liked the idea of a smooth floor, extra structure, and that he could use it for temporary heating even before the floor was finished.  

Aside from the fact that Warmboard gives you very even heat, it seems to move the job along quickly. For the heating contractor it gives you a good guide for installing.  The installation ease and performance of the product is superior to other methods like concrete topping or stapling underneath and insulating. With Warmboard you just have to snap the tubing in there with a rubber mallet.

We’ve worked with Uponor quite a bit and Watts, and in slab, under slab, under joist, topping on top of plywood, ceiling radiant, wall radiant, virtually every way of possibly doing it, and I think the Warmboard situation probably is the simplest and easiest… an elegant solution to radiant heating a home.”

Winterburn Construction, California

"Warmboard has become my company’s and my client’s preferred radiant flooring heat option over the last fifteen years.

Warmboard makes installation of their product easy for first time users. The product is delivered directly to your construction site equipped with plans for layout and an installation kit. You will need two people to install the product with ease; simply follow the plans provided, each sheet fits together like a puzzle and installation actually becomes fun. One tip to first time installers: frame exterior walls, install tubing then frame interior walls.

From our engineering and building perspective there is no comparable product. Warmboard, replaces traditional subfloor and reduces the weight factor of gypsum concrete, thus significantly lowering engineering and construction costs. Ultimately, you’re provided a superior subfloor material.

From our client’s perspective, we have only had positive feedback. Warmboard radiates the heat back up instead of into the flooring system; it’s covered with a sheet of aluminum that reflects the heat upward. The energy costs for our clients are significantly lowered by Warmboard’s energy efficiency.

Architects, engineers, builders and homeowners I’ve worked with like Warmboard because it lowers building costs providing the client with a substantially superior product to traditional radiant heat flooring."

The Yellow House: For Adults with Autism, COLORADO

The Yellow House in Carbondale, Colorado is a unique project designed specifically for adults with autism. As such, extensive design considerations were made to ensure the house would accommodate individuals with a wide spectrum of sensory sensitivities. One factor of particular importance is air movement, which some individuals have a heightened sensitivity towards. Warmboard provided a huge benefit over forced-air systems in this regard. Also of concern is the climate. Located just a few miles from Aspen, the Yellow House required a heat source that would be able to quickly and efficiently heat a home when the weather changes rapidly or drops to single digit temperatures.


Scott Schlicter
House Manager

The Yellow House is something that has evolved over the last decade or so. Eleven or twelve years ago they started a summer sports program where they would rent dorms at a local college. These summer camps eventually evolved into skiing and snowboarding camps in the winter. Flash forward and all of these 12 and 13 year olds who had been coming to camp for years and years were growing into young adults with no place to go for the assistance and support they need. Basically, we’re trying to find a solution, other than a group home or institution, for all of these people with autism entering adulthood; which is starting to number in the millions every year. We are trying to find a new solution; one better than the old institution and group home system from the 50’s and 60’s which has never really been overhauled. For some of these young adults with more pronounced behaviors, it’s hard for them to live in a community or home because most will kick them out if they run away, self-injure, etc. So we are trying to design a model that is a safe place for these adults who would otherwise be institutionalized. A lot of that was accomplished through the construction; planning space and color schemes. This includes anything from the safety of windows and blinds on the interior, to EMF free zones in the bedrooms, heated floors, sound-proof walls, and close monitoring systems with cameras in the public areas and microphones in the bedrooms to conserve privacy in their private places. The remodel was extensive – every single wall and floor was moved except for the stone living room; even the stairwell was moved. There is huge demand for houses like these. Four months in, a young woman that I teach skiing to was having some behavior issues and came and spent time at the Yellow House. Now her father is willing to foot the bill for a second one; and that’s only four months in. He is like so many parents we encounter. They make it through those teenage years and then their child is in their 20’s and all of a sudden their parent’s are like, ‘Now what do I do? They’re adults and they’re going to outlive me.’ We haven’t even really finished the Yellow House yet but we’re already in plans for a second because there is so much need. We must figure out how to care for this group of people who are physically healthy but need assistance mentally. These folks are going to live to be 80 or 90 just like everybody else. Warmboard is great. We have it in our ADU as well as the main house and I love the theory behind it. It just makes sense to heat where your feet are and you are, and not to blow hot air into a room and into the ceiling. It also provides some insulation, because there are lots of people that like to jump as part of their ‘stimming' (self-stimulation) and it helps with the sound so that it doesn’t sound like a beating drum when you’re jumping on the second level. Warmboard has been really responsive and comfortable. It’s fun when people who aren’t used to heated floors, or Warmboard, stay in the house and they say, ‘Oh, this is really nice.’ It’s just been wonderful.”

Jim Pidcock
High Mark Development

“Every person who is on the autism spectrum has a unique set of experiences, and so we have to cater to that and try to minimize the effects of the sensory issues. We did a lot of research with EMF (electromagnetic frequencies) and minimizing electric current running through the house through different types of systems. The heating is a big deal with that, so while it may just be coincidence that Warmboard is helpful negating some of the sensory issues, that’s important to point out. That was part of the process, sitting down as a design team and concluding that Warmboard was really going to help negate some of these potential sensory issues. Also, we do a lot of radiant in-floor heating in this part of the country, and its pretty easily sold in terms of the concept. We are at a higher altitude and generally our winters are colder than in other parts of the country. Once people get used to it, they kind of get spoiled to it. That was certainly one of the factors. Another thing that probably had a lot to do with our decision was the ease of installation. While a couple of my contractors were familiar with Warmboard, others were not, but the installation kit made it easy for everyone. They thought it was going to take much longer than it did, and it actually took less time than anticipated. That was definitely helpful. The design process went well, and what we ordered is what showed up. The plans were well thought out, the product works well and we were able to tailor everything to our specific project. I think that’s a huge deal. With a forced hot air heating system, if you’re going to keep a house warm, you’ve really got to run the thing a lot - especially in this climate. If it gets down to low temperatures, twenties and teens and zeroes, and less, the heating system is going to be running a tremendous amount of the time. The radiant heat allows for less movement and less sensitivity to it. And I know in the future we’ll be using your product again regardless of whether it’s a house that involves people with autism or just a run of the mill project. The design and considerations of the Yellow House are for a very specific clientele, and while we build for anyone, this project is… I don’t want to call it unique, but it’s certainly rare. That being said, there is a high prevalence of people on the autism spectrum, and every year there are more and more people, so as we get into the future houses such as this one are going to become more common.”

Steve Novy
Green Line Architects

“We like the idea of using radiant heating in the floor. It’s an efficient system, as compared to other heating options, because you’re heating the floor itself and the space people are occupying. Because this was a remodel, we also liked that we didn’t have to tear out the floor, we could simply install Warmboard on the existing sheathing. It was pretty straightforward and added some strength and additional structure to the floor. We felt this was a much better alternative to a Staple-Up kind of condition because we know that Warmboard allows for a better distribution of heat over the entire service. Also with Staple-Up it’s hard to get access either from the floor joists or the room below. And comparing it to radiant tubes being put into a gypsum concrete or lightweight concrete slab, here we didn’t have to factor in additional loading from the slab, so that was nice. We didn’t have to think about the extra weight concrete would add to what is essentially a turn of the century structure. Plus the ability to get an efficient in-floor heating system that’s hydronic; I think that’s the ideal scenario for us. We get better zoning with hydronic, and in addition to the points mentioned earlier about heating the space that people are occupying, with forced air you get stratification and other issues. Not to mention the fact that we didn’t have to put in a lot of ductwork. We paired the radiant in-floor heating system with an HRV, and the HRV ducting is simple, just six inch solid and flex ducts which are easy to route in an existing structure. I like the concept of Warmboard and I’ve been trying to find a good project for it. Now that we’ve done a successful installation we’ll certainly recommend it again. I’d like to follow up with the contractor and see what the costs are but I believe it’s going to be very comparable to other types of radiant systems, especially in remodel situations. As you know, this is a unique project. And it’s a fascinating to see how the needs of people with autism differ from a more typical kind of project we are involved in. We learned a great deal and will continue to learn as we evaluate how the Yellow House performs. I’m just happy that we’ve been able to use good mechanical and electrical systems that meet their needs. We also looked into a lot of other things such as the durability of products and the ease of cleaning various surfaces, and Warmboard fit well into that entire spec scenario. There was a side benefit to the aluminum in Warmboard. We were thinking we might have to shield between floors, but decided it was unnecessary because we already have an aluminum layer as part of Warmboard, so that’s kind of a neat thing. We’re very excited about getting to use the product and will certainly be recommending it in the future. We’ll also be evaluating the performance over time so we should check back in a year or so and see how everything’s working. We are looking forward to doing more projects like this to be honest with you.”


Sobek Architects, Wisconsin

In this Warmboard Works we hear from Marc Leveque of Sobek Architects speak about his thoughts on Warmboard and its competitors. Marc is a seasoned architect who has amassed a wealth of knowledge on building materials from his 40 years in the industry.

“I wanted to let you know that people’s reaction to it is REALLY impressive. That’s the truth.  No negative on it at all. So good product, and good for you guys, I’m glad you make such a nice thing. I want my clients happy and your product really brings that about every single time.

I always recommend Warmboard to my customers because it’s a replacement product. With Warmboard you can substitute it for the subfloor, which keeps costs down. That appeals to me. When you use cement floors they go on over the subfloor, which is a redundancy. And then you still have to adjust your framing, stud wall heights, and the list goes on. With Warmboard, those extra considerations are non-existent.

Warmboard is, in a kind and decent way, a boring product. It’s perfect; you don’t even know it’s there. That’s why I love it. You install it, no other structural parts are needed, and it solves several problems. That to me is the selling point. Every other product that you get in the market is an add-on, costs are always rising and everybody is pricing their way out of the market.

Warmboard did nothing to enhance or take away from our projects. Most people would think that’s not very nice to say, but it’s a mega compliment. Warmboard didn’t get in the way. It solved a lot of problems without making an architectural statement.

When you have a garage door with all sorts of square boxes in the garage door it makes an architectural statement. When you have a flat skylight in your roof, that’s architecturally neutral. Warmboard is architecturally neutral which makes it easy for me to work around. I’m not interested in changing the shape of my roof, or changing the shape of my floor. That’s what makes it perfect, because it’s not in the way.

Warmboard is one of the best products I’ve ever seen, and I’ve been doing this stuff for over 40 years. Everything on the product is so elegant. It’s so out of the way that you don’t notice it; that’s how good it is.

I had a client that said ‘I want a house that is so great that every boat on the lake stops to look at it.’ And I said that’s a nice dynamic, try this…how about that they drive by and it’s so perfect they don’t notice it, but they come back because they know they have seen something wonderful. Warmboard is that. People walk in, they’re comfortable, they’re happy, they love the house. And Warmboard is a part of that, but it’s so inconspicuous that you don’t notice it. That’s what makes it a winner.

I keep samples of Warmboard in my office. When I show clients what it is, and how great it is they say, ‘I’ve gotta have that.’ Everybody that I know of that has it loves it and there is no way they would ever change it. I have clients tell me ‘it’s like walking on a beach’, and ‘go ahead and try to take it away from me!’"
