Radiant Floors Application Information Sheet (107KB PDF)

Radiant floor heating directs heat upward into the room. To ensure effective and energy efficient operation of the system, particularly for under-slab floor designs, including insulation is critical. Properly insulating radiant floor systems makes it possible to provide maximum comfort at minimum cost. Install STYROFOAM™ extruded polystyrene insulation under the slab to provide moisture protection and to prevent radiant floor heat from dissipating into the ground. STYROFOAM extruded polystyrene insulation features high compressive strength to satisfy a variety of loading situations, and superior moisture resistance to provide long-term R-value for radiant floor-under slab applications. It is tough and durable to withstand normal construction site handling and is easy to cut and install.

There is a STYROFOAM insulation solution for every Radiant Floor-Under Slab application:
