WHY TREX PROTECT?

IT’S THE MOST COST-EFFECTIVE WAY TO EXTEND THE LIFE OF YOUR DECK

Trex Protect Joist Tape and Beam Tape is a self-adhesive deck flashing tape designed to protect wooden joists and beams from moisture that can lead to rot, splitting and the loosening of deck screws and fasteners.

Trex Protect works on horizontal and vertical surfaces and is applied as a “cap” (vs. wrapping), which allows the wood to breathe. This butyl-based self-adhesive tape is superior to asphalt-based joist tape and beam tape because it won’t bleed, dry out as quickly, or curl up and hold water. As a result, it acts as a moisture barrier between wood and galvanized metal commonly used in construction hardware.

Trex Protect Joist and Beam Tape is available in two widths making it easy and convenient to apply to double beams and joists. Use 1-5/8” (4.13 cm) Joist Tape for joists and 3-1/8” (7.94 cm) Beam Tape on all double beams.

TREX PROTECT EXTENDS THE LIFE OF YOUR DECK

Today’s high-performance composite deck boards, like those of Trex, are warranted to last 25 years. But, research shows that the deck substructure can begin to spilt, rot and decay in as little as 8-10 years.

To protect an average size deck measuring 12’ x 24’ will require approximately 5 rolls of Trex Protect Joist Tape and one roll of Trex Protect Beam Tape. For less than a $100 investment, your deck substructure can last as long as the decking it supports.
