Liner Butyl Tape
$20.00 – $130.00
If you are investing the time and money to install Dura Skrim Vapor or Vapor/Gas Barrier, make sure to use the real seam tape, DIY Seam Tape. Using anything less could be the same as leaving the seams unsealed. DIY Seam Tape is made of Polyethylene, same as you’re Barrier.
Liner Butyl Tape is Perfect for Encapsulation
Would you leave a window open all winter? No. You would close it and lock it and make sure it holds out the cold.
In the same way, your building encapsulation project will have seams where panels of Barrier meet. Each seam is a potential open window. Seal all seams using the best methods and the right products to ensure a complete building envelope.
Method: Water, water vapor, gases, etc., will find a easiest way in or out. A properly sealed seam is just as protective as the Barrier, not letting anything pass through. Double seal it. A proper seam should always have a 12” overlap of material. The first seal goes between the Barrier layers 3” to 4” from the edge of the lower Barrier. Use a continuous bead of Polyurethane Sealant (at least ¼” x ¼”) or a continuous strip of double sided Butyl Tape (at least ¾” by ¼”). Then, use 4” DIY Seam Tape to seal the edge exposed edge. (If you have access to both sides of the barrier – if you are hanging it vertically on framing or from a top support – use DIY Seam Tape on both sides to seal both exposed edges.)
The rubber adhesive of this Polyethylene tape is ideal for use with Polyethylene Barriers, it grabs fast, holds and seals tight, stays flexible, and can be removed, in one piece, with no residue. (DIY Seam Tape is an indoor/outdoor tape. The recommended temperature range is 32 F to 160F.)
