It is AAMA 711-13 compliant and its 11” width replaces the need to use multiple strips of tape, saving valuable time on the job site.

Reinforced with an aluminum liner, the 11”-wide tape covers the entire surface of the ledger board and creates a seamless seal over any gaps between the ledger and deck substructure for optimal protection against moisture and water penetration.ĭesigned specifically for deck applications, both in its function and size, Trex Seal features a convenient 5.5” double-release liner that allows installers to bend and set it in place without it flexing back like other flashing tapes. Trex Seal, when used as part of a Trex RainEscape system installation, takes ledger flashing to a whole new level by combining the best performance features of metal and tape flashing in one easy-to-use product. For waterproofing, flashing tape is substantially better since it is self-adhering and creates a tight seal on boards and around hardware. However, because traditional metal flashing attaches to the home using nails or screws, water can still seep into screw holes and penetrate the wood, causing it to rot and the screws to rust. Protecting the ledger boardwith proper flashing is critical for ensuring the structural integrity and longevity of a deck. Additionally, the natural expansion and contraction of wood over time can cause the ledger board to weaken, split and deteriorate. In most deck installations, there is a small gap left between the house and the deck that allows water to seep down and onto the ledger board, where it can collect and penetrate the wood, eventually leading to decay. “They were also unanimous in their feedback regarding the cause of ledger board failure – moisture.”Įasily one of wood’s worst enemies, moisture is a recurring theme across ledger board failures. “We surveyed professional deck builders and in almost every case they cited the ledger board as the primary source of deck failures,” said Dave Kile, founder of Trex ® RainEscape ®, which manufactures Trex RainEscape and Trex Seal products. With this in mind, the makers of Trex® RainEscape® have introduced Trex® Seal™ Ledger Tape, an 11”-wide aluminum-lined butyl tape specifically engineered for use on the ledger board of a deck.

If not correctly installed and protected, this single element can be the downfall of a deck’s structure. Englewood, CO., – Ask any contractor where a deck is most likely to fail and, chances are, they’ll point to the ledger board.
