Keene's CAV-AIR-ATOR is a full-wall drainage and ventilation mat for full brick or stone masonry walls.
- Protects against moisture issues and maintains an unobstructed air space for drainage and ventilation
- Fills the air-gap between a brick and veneer and the back-up wall
- Prevents mortar drippings from falling in the cavity, clinging to wall ties or blocking weep holes during construction
- Extremely light and flexible so it can rest on top of brick ties
