Trex Seal Sub-Ledger Tape fights ledger failure

Trex Seal Sub-Ledger Tape is 22” butyl-based tape that creates a moisture barrier between a deck ledger and the house. Waterproofing the ledger board is a critical step in preventing moisture damage and ensuring the structural integrity of a deck over time.


Inspired by the success of its Seal Ledger Tape, the new sub-ledger offering features similar performance features and benefits in a wider product designed for this specific application. Reinforced with an aluminum liner, the 22”-wide, self-adhering, butyl-based tape fully covers the back of the ledger board and integrates with the house wrap to provide a continuous seal for optimal protection against moisture and water penetration. It also creates a water-tight seal around ledger fasteners.


It is designed for easy application with a convenient triple-release liner that allows installers to bend and set it in place without it flexing back like other flashing tapes. Its width replaces the need to use multiple strips of tape.
