ABSTRACT:
Disclosed is a rigid, thermoplastic foam board useful in below-grade residential and commercial insulating and drainage applications. The board defines a plurality of oriented channels extending therein along the board. The channel extends into the board through a relatively narrow first opening at the face into a relatively wide first zone. The channel then further extends into the board from the first zone through a relatively narrow second opening into a second zone. The board provides superior water drainage, and protects a below-grade building wall from excessive moisture. Further disclosed is a method for using the foam board in below-grade applications.
