What is Trex Protect?
Trex Protect is a non-skid, self-adhesive deck flashing tape that is designed to shield the tops of joists, rim joists, beams and ledger board from moisture that can lead to the development of rot and wood decay 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 Tape and Beam Tape have a non-skid surface making it easier and safer to walk across during construction. Available in two widths – 1-5/8” (4.13 cm) for joists and 3-1/8” (7.94 cm) for beams, Trex Protect is a simple and cost-effective solution to combatting the damaging effects of both Mother Nature and Father Time.
