Ledger Tape Locks Out Moisture

Trex Seal Ledger Tape is an 11-inch-wide aluminum-lined butyl tape engineered for use on the ledger board of a deck. Deck ledger boards are a primary source of deck failures due to moisture. Due to a gap between the house and the deck, water can seep down onto the ledger board, where it can collect and penetrate the wood, eventually leading to decay. The tape, especially when used as part of a Trex RainEscape system installation, supports the flashing. It is reinforced with an aluminum liner and covers the entire surface of the ledger board, creating a seamless seal over any gaps between the ledger and deck substructure for optimal protection against moisture and water penetration.
