DC14 Drainage Mat was designed following rain screen principles to allow ample space for drainage and drying between exterior wall cladding and wall sheathing. With drainage channels on both sides, it permits easy drainage for water and allows air movement between the cladding and sheathing to help keep the wall dry. It is ideal behind exterior claddings that are closely attached to the wall sheathing, such as traditional stucco, stone, thin brick veneer, and siding. Because DC14 is made of extruded polystyrene (XPS), it does not absorb moisture and is not a food source for mold.

● Allows air movement for drying
● Drainage channels on both sides
● Lightweight
● Easy to handle and cut
● Compatible with stucco, stone, fiber cement, wood and vinyl claddings
● Does not absorb moisture
● Virtually unrestricted drainage and drying

3 DC14 Drainage Mat was evaluated in accordance with the ICC-ES Acceptance Criteria for Foam Plastic Sheathing Panels Used as Water-Resistive Barriers (AC71). The product was installed over wood sheathing as an alternative to building paper or housewrap. All horizontal and vertical seams were sealed with GreenGuard ® Contractor Tape and the interface between the window frame and the DC14 was sealed using GreenGuard ® Self-Adhering Flashing. All other wall penetrations were sealed using either spray foam, caulk, adhesive tape or self-adhering flashing membrane. Refer to ICC-ES Evaluation Report No. ESR-2136 for details regarding the use of other GreenGuard Fanfold Underlayments as water-resistive barriers.
