Protect your deck structure and add a whole new outdoor living area with the Trex RainEscape deck drainage system!

Trex RainEscape Wall Flashing seals the gap between your house and your deck boards, preventing rot and other structural damage. This self-adhesive wall flash is easy to install between your house - just use your first deck board to compress the flashing and then continue installing deck boards normally.

The Trex RainEscape deck drainage system is the perfect way to enhance a deck, creating dry space where you can run wiring for lighting or ceiling fans beneath your deck boards.

Trex RainEscape Wall Flash comes in 25-foot rolls that are 1 inch wide and 1/4-inch thick.

Please note: this system can only be used for new projects; it cannot be installed on an existing deck.
