Designed to respond to the needs of building professionals and homeowners, UnderShield is easy to install to new or existing decks, and will maintain unobstructed air flow when properly installed. Panels can run parallel or perpendicular to the home, and an easy-to-use clip creates the desired pitch. UnderShield is dry by design, incorporating a special shield with channels that discreetly collect and drain precipitation away from under your deck, leaving the space beneath dry and comfortable.
