RDBP consists of a double layer of polyethylene bubbles, sandwiched
between a metalized aluminum sheet, and a white polyethylene surface.
It is ideal for many under-slab insulation applications, as the aluminum
surface is treated with a coating designed to protect it from corrosion.
Using RDBP in your construction project improves
the efficiency of radiant heating systems, and significantly reduces
heat-loss to the ground below. RDBP is also an approved
vapor barrier.
