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 3/4" PEX-AL-PEX.
Package includes (8) 2ft x 4ft panels, equaling 64 sqft of coverage.
Features: - Cuts radiant heat installation time by 2/3
- Designed to hold PEX tube securely in place with wider and deeper fastener
- are less susceptible to damage from foot or equipment traffic
- Lay flat and use tongue & groove system to interlock
- UV protected packaging for outdoor storage and are less susceptible to damage from foot or equipment traffic

Ask a Question
are these suitable to use under a driveway with 6 inches of concrete?
I worry they may compress causing the concrete to cure un level.
It's a 2lb/cubic ft density foam, specifically intended for concrete pours with radiant floor heat. It's used for residential and commercial projects. If the gravel underlayment is level and well compacted, there's no reason for any significant compression unless the driveway is used by heavy machinery or delivery trucks. The board will compress by 10% if 3,600 lbs of weight is applied to 1 sqft of area.

Can we put on a concrete slab and then flooring on top of the heat panels?
These panels are not a structurally solid substrate for any kind of floor installation. These are intended for use under the concrete slab only.
