Under Concrete Insulation 300 S F

EcoFoil Ultra Under Concrete Barrier is constructed using a patented design, with a layer of pure aluminum bonded to and sandwiched between 2 layers of strong polyethylene bubbles. This breakthrough design is ideal for use underneath radiant heated floors. Laminating the reflective foil in between the sturdy bubble insulation ensures the life and performance of the foil by protecting it from corrosion and deterioration.Traditional foam sheet insulation can crack and break under pressure, and does not provide protection against thermal energy transfer, moisture vapor, or radon. EcoFoil Ultra Under Concrete Barrier is designed to block harmful ground elements from seeping up from below while reflecting heat from above back into your home or building - keeping your concrete dry and at a uniform temperature.All radiant barriers need at least a small amount of air spon both sides for the foil to reflect properly. Placing the foil layer in between the polyethylene bubbles creates both an insulator AND a radiant barrier, because the bubble layers provide R-value, as well as that air spwhich the foil needs to properly reflect radiant heat. Features: Patented Bubble/Foil/Bubble Design - 300 square foot roll (4 X 75) 57% Reflectivity, 43% Emissivity, 100% vapor and radon barrier Creates a thermal break between ground and slab, Moderates slab temperatures Strong 140 PSI compression rate, High 85 PSI puncture rate Designed specifically for use under concrete with radiant heating systems
