Today’s high-performance composite deck boards, like those from Trex, are warranted to last for 25 years or longer.
But what about the substructure material underneath?If the posts and beams that support the deck are made of wood, they are likely to deteriorate long before the decking warranty elapses.
Now, there is a simple and cost-effective solution to combatting the damaging effects of nature and time.Trex Protect Joist and Beam Tape is a self-adhesive butyl tape designed to protect wooden joists and beams from moisture that can lead to rot, wood decay and the loosening of deck screws and fasteners.
Trex Protect works by shielding the tops of joists, rim joists, ledger boards and beams from moisture.It also acts as a barrier between wood and galvanized metal commonly used in construction hardware such as joist hangers.
Additionally, Trex Protect seals deck fasteners and helps deck screws hold longer and stronger by preventing moisture penetration and defending against splitting that can result from seasonal freezing and thawing.
Available in two widths 4.13cm for joists and 7.94cm for beams – Trex Protect works on horizontal and vertical surfaces and is applied as a ‘cap’ (vs. wrapping), which allows the wood to breathe.
