EcoFoil Under Slab Insulation is a patented breakthrough product in the concrete slab insulation industry. It is specifically designed for use as a thermal barrier under concrete and works superbly with radiant heated floors. The under slab insulation (1/4" to 5/16") thick, is manufactured with a single layer metalized reflective sheet laminated between two layers of strong polyethylene bubbles. EcoFoil Under Slab Insulation has an R-Value of 3.8 and a compression strength of 140 PSI. Our under slab insulation is thin and lightweight making it easy to conform to your grade and reduces any worry of leaving pockets or voids like traditional insulation. Unlike traditional bubble insulation, where the foil is exposed, our patented product is encapsulated. This was done for two main reasons; the integrity of the foil and the airspace it creates for effectiveness. If the foil surface comes into direct contact with certain acidic soils it can corrode the reflective properties of the insulation. This can also happen during the curing process of concrete. For this reason, standard radiant barriers or bubble insulation are not an appropriate insulation for an underground application. It is also important to maintain an airspace on one side of the insulation in order for it to be reflective. By laminating the reflective metalized sheet in between two layers of our sturdy bubble insulation we have ensured the integrity of the foil by protecting it from corrosion and deterioration. We are also maintaining an air space by placing the foil in between the bubble layers. Most importantly, EcoFoil Under Slab Insulation reflects 57% of the radiant heat back up towards the surface, whereas without under concrete insulation, this heat would travel down and be lost in the soil. Additional benefits are that the under slab insulation provides a vapor and radon barrier. The seams of under slab insulation must be taped together so when finished the insulation acts like one sheet. Just like the name implies, this insulation can be used under any concrete slab to reflect 57% of radiant heat. This includes new construction and remodeling applications. EcoFoil Under Slab Insulation is the perfect product to use with a radiant heating system. It will make your heating system more efficient by reflecting 57% of the radiant heat, creating shorter run times and less cycles throughout the day. Another use is on top of an existing slab before you put down carpet pad and carpet.
