ThermaSlab combines subfloor, radiant heat, and gel-cushion isolation in a factory-finished unit. You frame once. The system is already inside.

ThermaSlab panels are currently in pilot production. We're working with a limited number of contractors and design teams on specification, first-install feedback, and early pricing.
No separate heating system. No separate underlayment. No separate finish floor. One unit.
Replaces standard OSB or plywood subfloor. No additional structural work required. Install once, done.
Hydronic tubing pre-routed in the panel. Connect to your boiler or heat pump, zone by zone. No messy staple-up, no aluminum plates.
Absorb impact, reduce footfall noise, add thermal inertia. Better acoustics in multifamily. More comfort in residential.
Hardwood or marble finish applied at the factory. No on-site finish work. No sanding, no sealer, no wait time.
The floor is the most underutilized surface in a building. It holds everything. It touches every room. And in new construction, it's still just plywood and hope.
ThermaSlab was built to change that. A single panel that replaces your subfloor, your radiant heating system, your underlayment, and your finish floor. Fewer decisions on the job site. Fewer failed handoffs between trades. A better result for everyone.
We sell to builders, wholesalers, and distribution partners who want a product that ships right, installs fast, and makes their buyers happy.
