Heat-Sheet Cost Comparison
Heat-Sheet vs Pink Foam Board: Look Beyond the Price per Panel
At first glance, standard pink foam-board insulation may appear to be the less expensive choice. But the insulation is only one part of the full installation. Let's look further...
Where Heat-Sheet Can Save
Potentially Eliminate the Separate Vapor Barrier
Depending on the Heat-Sheet product selected, panel thickness, application, and local building requirements, an additional vapor barrier or vapor retarder may not be required.
(Always confirm vapor-barrier requirements with the local building official before beginning installation.)
No Long Rows of Panels to Tape Together
Heat-Sheet panels interlock to create a stable installation surface. Instead of laying that foam and then spending time taping joint and joint, workers can connect the panels with the simple interlocking system and continue along the floor.
Walk the PEX into place
The formed nodules hold the radiant tubing (PEX Pipes) at a consistent spacing while allowing the installer to press the PEX into place while standing. Pretty nice on your back!
One-Worker-Friendly Installation
Heat-Sheet panels measure approximately 2 feet by 4 feet, making them manageable for a single person. Once the panels are in place, one worker can begin walking the tubing into the grid without needing another person to hold the PEX while it is stapled. While crew requirements vary by size and layout, Heat-Sheet can help an installer complete more of the installation with fewer people, OR allow a DIY installer to make meaningful progress without waiting for additional help.
What's Happening in Cottonwood?
Extreme Panel's demonstration house brings building techniques into the real world. As a sponsor, HUG Hydronics is providing Heat-Sheet, PEX, and the in-floor heating distribution system for the project.
Fellow EP Summit sponsor BUILD Show Network is documenting the process with cameras, interviews, and a closer look at each step of the process, leading up to the January 2027 Summit.
See the build come together.
Take a closer look at the project, then explore what radiant in-floor heating could look like in your own home, shop, or garage.

What HUG Hydronics Brings to the Project.
- Start below the slab
- Heat-Sheet insulation provides the foundation for the project's radiant floor.
- Put warmth underfoot
- PEX loops carry heated fluid through the floor, turning the slab into part of the heating system.
- Bring it together with HUG Hydronics
- The HUG Hydronics system brings pumps and controls into a compact system simplifying the mechanical setup that serves the floor.
No. The Wizard is designed to walk you through the basics in plain language. Homeowners and building professionals can use it to explore what their project may need.
HUG Hydronics is sponsoring Extreme Panel's project by providing its in-floor heating materials and system. BUILD Show Network is a fellow EP Summit sponsor documenting the demonstration house. The summit is planned for January 2027.
Yes. Call HUG Hydronics at 218-587-5001 or email sales@hugllc.com. Additionally, completing the HUG Wizard is a useful first step toward discussing your program.
Nope, and we love Extreme Panel's way of building, however this project showcases only one type of application of HUG's system. HUG Hydronics can also be used in other homes, shops, garages, and ag buildings where radiant floor heating is appropriate.
Have your floor plan or approximate dimensions handy, along with basic details about your insulation, ceiling heights, and windows. Think about which spaces you'd like to control with separate thermostats. The Wizard will guide you through the planning process, and HUG's team can help review your project's needs.
