HydroFoamTM maximizes radiant heat insulation for residential, and commercial construction projects by ensuring the heat is dispersed evenly throughout the entire floor area, providing building occupants with a more comfortable living and working environment. 

NUDURA has brought innovation to the market with our line of Insulated Concrete Forms and that innovation continues with HydroFoamTM. Installation is fast and easy compared to traditional radiant heat insulation which requires multiple steps to run radiant heat piping - Watch the radiant heat installation Video. The 4’ x 4’ (1.2 m x 1.2 m) boards are 2 1/2“ (64 mm) thick and easily installed with an overlapping interlock on all four sides, ensuring the boards are locked in place during installation. HydroFoamTM utilizes a 360° multi-directional friction fit anchor system that eliminates the need for wire mesh. Radiant heat piping is easily stepped into place in any direction required.

HydroFoamTM offers installers a lightweight high density expanded polystyrene (EPS) radiant heat insulation product that increases installation speeds, is easily cut to meet any angle or radius while providing R-10 of insulation value.
