Ultra Under Concrete Barrier is a breakthrough in the Concrete
Insulation market specifically designed for use in under concrete
applications. Ultra Under Concrete Barrier provides a superior radiant
and vapor barrier as well as a thermal break. The patented design
consists of a sheet of 99% pure aluminum laminated between two layers
of strong 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.
