Rainshed Decking
Did you know that most composite decks have a wooden frame?
Even #1 grade pressure treated pine does not come with the protection it once had. Because of this, rot failure in decks occurs far more frequently than in the past. Rainshed Decking is a product that diverts water that normally comes through the decking, out the ends of the deck. This does not just allow for dry space below; the primary function of this technology is to keep dry the wooden frame of a deck.
Beginning in 2003— due to health concerns— the Environmental Protection Agency began working with wood preservative manufacturers to phase arsenic out of treated lumber. A multitude of different treatment methods have been used since, but none have been as effective at preventing rot as solutions containing arsenic. The common unavailability of old growth lumber has also led deck frames to be constructed with less than desirable material. Most composite deck frames use treated pine, meaning decks with plastic decking are still subject to rot failure.
Unlike other composite deck boards,
Rainshed Decking prevents rotting frames.
Keeping the frame dry eliminates many problems associated with wooden and traditional composite decks. Rainshed Decking is highly successful at preventing your wooden frame from getting wet, thus eliminating most risks for rot and unsightly algae, mold, and mildew. Other typical problems associated with wet, aged lumber— such as deteriorating fibers surrounding fasteners and deflecting (sagging) joists and stair stringers— are also prevented using Rainshed Decking. Letting these issues occur is how decks lose structural integrity over time. Rainshed Decking lets your frame last longer by keeping water off the frame.
Rainshed boards are solid, single component products that have water diversion channels formed into them. Boards are laid over one another in a fashion that hides these channels in the cracks between each board top. Rainshed Decking is fastened from underneath the deck board, meaning minimal exposed screw heads and no poor performing hidden fasteners. Rainshed Decking is the first and only fully solid water channeling deck board. No gaskets are required.
Smart deck boards require smart deck frames.
Proper water flow is achieved through a process called Frame Shaping. Without Frame Shaping, water stays in low areas of the deck caused by sagging and shrinking joists. The components involved with Frame Shaping raise parts of a deck board, creating a slight convex shape on the surface of the deck. This prevents water from pooling in the deck board by ensuring most waterflow at the front of the deck, thus minimizing the amount of water building up inside which overflows in the channel and gets the frame wet.
During heavy rainfall, a significant amount of water is also diverted through a diversion channel made from EPDM rubber or rigid vinyl located at the house to protect the ledger board.
Proper general upkeep (cleaning the channels) is required to prevent leaks due to blockage. Rainshed Decking is not a roofing product and should not be used for such.
Rainshed Decking and other related composite deck components are available in a variety of colors.
