- About MTI
Gravity CavityTM rainscreen drainage plane (draiange mat) is the economy alternative to our Sure CavityTM drainage plane (drainge mat) product. It works because it maintains a separation between the materials used for the veneer and the structural back-up wall. Gravity Cavity’s 1/8” deep channels are better than fiber-based mesh because they enable moisture that enters the building envelope to travel quickly straight down and out the bottom of the wall, and they don’t compress behind siding.
