Joist tape is an essential component of a well-built deck! WiseWrap® JoistTape™ Butyl joist barrier tape Butyl is a self-sealing malleable polypropylene protective waterproof wood flashing membrane featuring a high-performance butyl hybrid self-adhering adhesive. It protects joists under the decking boards from premature wood rot, decay, and corrosion. JoistTape™ Butyl deck flash barrier features a high-performance butyl hybrid adhesive with a high strength nonslip polypropylene backing. Butyl joist barrier tape will self-seal around deck screws, nails and fasteners to prevent water infiltration, wood rot and lumber breakdown.
Butyl joist tape is less temperature-sensitive for installation with a low range approximately 25F. This extends the building season in colder climates or at elevation and allows it to start earlier. It maintains its stickiness at much lower temperatures than non-butyl barrier tape. Meaning, application of the tape can be done at colder temperatures. Easily apply to decking joists, around deck support posts and over ledger boards.
Water leakage through your decking boards can cause hidden damage unless your bearers and joists are covered. Even tiny cracks around screws can lead to timber rot. For a small cost, you can protect your deck substructure by applying flashing tape. JoistTape™ Butyl joist barrier can waterproof the tops of the deck joists, rim joists, bearers, and the ledger board. It will hold water out and self-seal around screw holes and metal fasteners to prevent corrosion and joist wood rot.
When this tape is applied to the top of decking joists, over ledger boards, and around support posts, it creates a waterproof seal that helps stop decay and wood rot. Rot is caused by moisture that stays in contact with treated and untreated lumber deck framing and the above decking material. When it blocks this moisture and prevents wood rot, the barrier tape will maximize the life of your brand new deck or restoration.
With our butyl rubber joist tape, it can be used on "damper" material. Such as if lumber is not kiln-dried or it is a dewy morning. Always prefer a clean and dry surface! It instantly adheres to most surfaces and has a high adhesion level. Butyl joist tape is less temperature-sensitive and maintains its stickiness at much lower temperatures than non-butyl barrier tape. Meaning, application of the tape can be done at colder temperatures. In addition, homeowners and builders appreciate how quickly they can repair with butyl seal tape.
Unique Non-Skid Surface: Beyond protection, our Joist Tape features a unique non-skid facer, providing grip in any weather for safer deck installations. UV resistance ensures durability even during extended periods of exposure, making it a reliable foundation for level decking.

Corrosive chemicals like alkaline copper quaternary (ACQ) and copper azole (CA), commonly used in pressure-treated wood, can corrode steel joist hangers and other metal hardware. Installing JoistTape™ Butyl barrier tape between metal and wood it creates a physical barrier that prevents the corrosion of the metal surface.
Q: How do I decide which width of JoistTape™ Butyl joist tape I need for my deck?
A: The answer is simple, it’s up to you or your contractor’s preference. Whereas some installers prefer only the top of the joist covered with the 1-5/8” width, others may want to wrap the joist top and sides with the 3-1/8” width. Also, the 3-1/8” width is perfect for double joists.
Q: Is JoistTape™ Butyl Joist Tape compatible with my deck surface material?
A: Yes, JoistTape™ Butyl Joist Tape works with naturally durable wood (e.g. redwood, cedar), pressure treated timber (e.g. southern yellow pine), exotic tropical hardwoods (e.g. ipe, teak, tigerwood), thermally modified wood, wood plastic composite (e.g. Trex, Monarch, TimberTech, Veranda), or plastic (e.g. polystyrene, PVC).
Q: Can I calculate how many lineal feet of JoistTape™ Butyl Joist Tape my deck needs?
A: Yes, you can calculate your deck square footage and estimate how much JoistTape™ Butyl Joist Tape it will need with the Coverage Calculator at the top of this page.

When protecting posts, WiseWrap® JoistTape™ Butyl Tape should be applied at the ground level with 2 to 3 inches (5 - 7,5cm) extending above the finished grade. For you to be able to determine the proper location on the post for product placement, you will need to insert the post in the hole, mark the post to indicate the grade level, and then take the wood post out of the hole. To decide what the proper length of tape to use; do the following: without removing the white release paper, wrap the material around the post, making sure that there is enough material for a minimum 1 inch overlap. Cut the JoistTape™ Butyl barrier tape to the correct length. Remove the release paper and wrap it around the post while firmly pressing it into place. To maximize adhesion, roll it on with a small hand roller. To help provide added protection against deep standing water around the post, a small bead of non-silicone caulk may be used at the top edge of the joist barrier tape.
