Trex RainEscape Under Deck Drainage System

100x100mm Post Flashing – Black


Trex RainEscape Post Flashing is used around 100x100mm Posts to prevent moisture penetration and damage. The Trex RainEscape post flash fits tightly around a wooden post and is slid down to provide a secure barrier where the wood post and deck frame meet. The post flashing can be fixed in place using the RainEscape butyl caulk and tape. It can also be trimmed down to size and covered by Trex decking boards if no post sleeve is used.

Trex RainEscape keeps outdoor living areas dry in rainy weather. This system does so without the appearance of unsightly downspouts or panels. It is an easy-to-install product that makes it simple to create stunning outdoor spaces. RainEscape keeps the area underneath a deck dry, so it’s possible to install TVs, speakers, ceiling fans, and more. Trex RainEscape is the perfect way to create an indoor environment underneath any deck. Don’t let dreary weather keep you from having fun outdoors!

TREX Changing The Way The World Lives Outdoors

The Trex company offer the most innovative, technologically advanced outdoor living products available today. As the first company to combine the durability of recycled plastic with the natural beauty of reclaimed timber in a high-performance decking product, Trex lead the way in applying this proprietary technology to a wide variety of outdoor applications for low-maintenance, luxurious outdoor living

Trex® eco-friendly composite decking boards are made from an innovative blend of 95% reclaimed timber and plastic—that’s almost the whole thing. And we’ve been this way for more than 20 years, well before green was a buzzword. Because in the end, all of us want to look out on our decks and know that we’ve done our part.

Trex composite decking boards don’t compromise on performance or reliability. They’re hassle-free and don’t require sanding, staining, or painting, which means less time working on your deck and more time relaxing outside. Your deck will look like new for years to come thanks to the protective outer shell on each Trex board, which can outlast harsh temperatures and inclement weather.

Since 1996 Trex has invented, defined and perfected the composite deck category, becoming the world’s largest manufacturer of timber-alternative decking products. Never content to settle, we continue to make strides in outdoor engineering, melding innovation with environmental responsibility and beautiful form with powerful function.

Formed in 1996 through the buyout of a division of Mobil Corporation, the company went public in 1999. Today Trex offer the industry’s widest array of high-performance composite products, which are available in more than 40 countries around the world.
