What Is Ultra Under Concrete Insulation?
EcoFoil® Ultra Under Concrete Barrier is a patented product and a breakthrough in the Concrete Insulation industry. It is specifically designed for use as a thermal barrier under concrete. Ultra Under Concrete Barrier provides a superior radiant and vapor barrier as well as a thermal break. It is also an effective radon barrier if properly sealed with our sealant tape. The patented design consists of a sheet of 99% pure aluminum laminated between two layers of strong, compression resistant polyethylene bubbles. Laminating the Reflective Foil in between the sturdy bubble insulation ensures the integrity of the Foil by protecting it from corrosion and deterioration. This product boasts maximum thermal value while also providing excellent reflectivity, keeping your concrete dry and at a uniform temperature.
Where Is Ultra Under Concrete Insulation Used?
Under Concrete Slabs with Radiant Heat - Ultra Under Concrete Insulation performs superbly when used under concrete slabs with a radiant heating system. It will result in warmer floors and faster slab response times which will reduce the BTU consumption of the radiant heating system.

Under Concrete Slabs without Radiant Heat - Ultra Under Concrete Insulation can also be used under non-heated slabs and
will provide an effective vapor, radon and moisture barrier. It will
provide a thermal value but each application varies in terms of efficiency.
