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 (12) 2ft x 4ft panels, equaling 96 sqft of coverage.

Features:

• Cuts labor by over 60% and allows for a 1-person installation - simply "walk the tubing in the board";
• 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;
• Lays flat, can be walked on and helps to protect the pipe from damage during construction;
• EPS provides stable R-value and does not need to be adjusted for age;
• CFC and HCFC-Free.
