HYDROFOAM maximizes radiant heat insulation for residential and commercial projects by ensuring the heat is dispersed evenly throughout the entire floor area, providing home owners 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 HYDROFOAM. Installation is fast and easy compared to traditional radiant heat insulation which requires multiple steps to run radiant heat piping. The 1.2m x 1.2m boards come in thicknesses of 64mm and 102mm thick and easily installed with an overlapping interlock on all four sides, ensuring the boards are locked in place during installation. HydroFoam utilizes a 360° multi-directional friction fit anchor system thHydroFoam pipe placementat eliminates the need for wire mesh. Radiant heat piping is easily stepped into place in any direction required. 

HYDROFOAM 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 U 0.56 or 0.35 of insulation value.
