Your home faces many potential hazards: fire, storm, pests. Yet, one of the most often overlooked elements can be the most destructive: water.
All it takes is a tiny gap and water can wreak havoc.
Trex RainEscape® Wall Flash minds that gap, so you don’t have to. This quarter-inch wall flash covers the tiny gap between your first deck board and your house — where big water damage can start.
How Does Wall Flash Stop Rot?
The first deck board is generally mounted slightly away from your house, leaving a small gap where water and ice can become trapped. Over time, this trapped water will cause your wood to rot.
If you live in an area with a freeze/thaw cycle, this protection is even more critical. The wall flash prevents ice build-up that can expand, contract and move the deck board over time.
How Should I Use the Wall Flash?
Wall flash is best used during the construction of a new deck. Easy-to-install, self-adhesive Trex RainEscape Wall Flash seals the space between your house and the deck to keep water out of the gap.
If you have a second-story deck, you could use the wall flash as part of our Trex RainEscape Deck Drainage System. When used together, you get more dry, usable space and protection from the damage caused by wood repeatedly getting wet. An over-joist drainage system not only completely covers and protects the entire wooden substructure; it also creates usable space beneath the deck.
Trex RainEscape® Wall Flash comes with a 20-year warranty from Trex, the world’s #1 composite decking brand. See how Trex RainEscape® Wall Flash protects in this video.
