Above The Joist System

  • Systems installed above the joist provide 100% protection of the deck substructure from moisture penetration.
  • By comparison, an under-the-joist system allows water to run through the decking boards, over the joists and into the drainage system below.
  • When the joists get repeatedly wet, they will eventually rot.

​Easy Installation

Installing Trex RainEscape is an easy 3-step process:

  • Install downspouts and trough
  • Staple into place
  • Tape all joints and seams​

Installation requires only three tools:

  • Caulk gun
  • Staples
  • Scissors or a utility knife

Add Utilities And More​

  • Trex RainEscape creates a dry space beneath an elevated deck.
  • Once installed, homeowners can finish the space by adding utilities for a ceiling fan, Trex RainEscape Soffit Lights, TV, gas fireplace and more.
  • An under-the-joist system does not allow for the installation of utilities because the space below the joists is not dry.
