Crete-Heat expanded polystyrene (EPS) floor insulation boards combine concrete insulation, vapor barrier and PEX tubing holding grid into a single product, which significantly simplifies installation of PEX tubing for radiant heating and snow melting applications in a concrete slab. No foamboard staplers/staples or wire ties needed.
Suitable for insulating slabs in basements, garages, warehouses, etc. - in below, at or above-grade installations (Note: below-grade installations will require a vapor barrier). Compatible with all types (A, B, C) and brands (Everhot, Uponor, Viega, Watts, Zurn, etc.) of PEX tubing. Also compatible with 1/2" PEX-AL-PEX.
Package includes (8) 2ft x 4ft panels, equaling 64 sqft of coverage.

  • Tongue & groove interlocking edges make installation easier - no glue or taping needed;
  • Knob design allows for spacing in precise 3" increments (3", 6", 9", etc.) - no chalkline needed;
