Why choose HYDROFOAM® insulation?

Thanks to its 4′ x 4′, 2 1/2″-thick boards that use an overlapping interlock technology on all four sides, HYDROFOAM® radiant heat insulation makes it extremely easy to lock the boards in place, minimizing installation times. HYDROFOAM® also boasts a 360-degree multi-directional friction fit anchor system that allows radiant heat piping to be installed in any direction. This type of radiant heat insulation uses a high-density expanded polystyrene (EPS) that offers an R-10 insulation value.
