ThermaFlo®

ThermaFlo^® - Protection, Drainage & Insulation

ThermaFlo combines the excellent thermal protection of Styrofoam™ Brand Insulation, superior drainage capability and protection to the waterproofing membrane - all in a single product. This 3 in 1, multi-purpose product is particularly well suited to below grade vertical foundation walls. ThermaFlo panels are 2 ft. x 8 ft. DuPont™ Styrofoam™ extruded polystyrene foam insulation with horizontal and vertical drainage channels on one side, covered by spun-bonded polyester fabric. Tongue and groove edges along all sides allow each board to be interlocked during installation, creating a continuous thermal and drainage barrier.

The advantage of ThermaFlo on a foundation wall is that it cuts labor in half, when compared to the installation of a separate protection layer and drainage composite. The thermal protection is an added benefit.
