UnderShield vinyl ceiling system

CertainTeed’s UnderShield is a vinyl ceiling system that turns deck undersides into dry, aesthetically pleasing areas for entertaining or storage. UnderShield features 6-in. by 16-ft. vinyl panels and a concealed clip and grid system that can be quickly installed to deck joists to divert precipitation to the edge of the deck. The panels are available in two styles, chamfer or beaded, and three color choices: Colonial White, Sterling Gray and Savannah Wicker.
