ThermaDrain combines a high quality closed cell, rigid board,  insulation with an adhered high impact styrene drainage panel that is incorporated onto its exterior face.

When installed within a masonry wall, ThermaDrain provides the wall with the required "R" value and forms a continuous unobstructed drainage path within the masonry wall.

ThermaDrain eliminates the need for a clean airspace in drainage walls. ThermaDrain is ideal for use in cavity wall and masonry veneer wall construction. Visit www.thermadrain.com for more information on this product.
