TYPAR’s new Flashing and Sheathing Tape (F.A.S.T.) may have been engineered to seam sheathing boards and flash windows, but did you know it can actually be used for much more?
The same aggressive, all-weather adhesive and tough, conformable backing that make it reliable at window and door details happen to line up with a handful of other jobsite scenarios—including those that have nothing to do with flashing.
Ask the contractors who’ve put F.A.S.T. to work, and you’ll quickly learn that it’s one dependable roll that can do the job of four.
Here are three additional applications where F.A.S.T. does more than its name suggests.
On drainable weather-resistive barriers like TYPAR® DrainableWrap™ and DrainableWrap™ Commercial, the raised orange meltshot fibers that create the drainage gap are also the reason crews typically reach for a double-sided seaming tape or a bead of sealant to lock down seams and laps. F.A.S.T. gives crews a simpler, single-sided option: its aggressive, all-weather adhesive bonds directly over those meltshot fibers—something a standard single-sided tape isn’t designed to do.
F.A.S.T. can also be used as a reliable field-repair for any weather-resistive barrier, TYPAR or otherwise. Nicks, cuts, punctures, or fastener tears that happen during construction can be patched on the spot, restoring the airtight, watertight performance the envelope was designed to deliver. No specialty patch kit, no second product.
Framing lumber takes a beating from moisture long before the finished deck ever sees a piece of furniture. Protecting joists, beams, and ledger boards from water intrusion is critical to preventing rot, and it’s exactly the kind of job F.A.S.T.’s tough, weather-resistant construction was built for.
While there is a dedicated category of joist tape products on the market today, each solving a single problem, F.A.S.T. gives builders and remodelers a way to consolidate their tools into a single product. If you’re already running F.A.S.T. for flashing and sheathing, the same roll can handle your deck and joist protection—no separate specialty tape required. That means one trusted product working across both your wall and deck assemblies, backed by the TYPAR Weather Protection System you already rely on. Fewer products to manage on the truck and one consistent standard of performance from the envelope to the deck framing? That’s a win-win.
Most building wraps, flashings, and adhesives are rated to roughly 180° F, but metal siding is an exceptional thermal conductor. Under direct solar exposure, behind-the-panel temperatures can easily climb past 200° F, putting standard-rated tapes at risk of adhesion failure. But F.A.S.T. can handle the heat. It is rated for installation and performance in temperatures up to 240° F, well above the 180° F ceiling typical of competitive products.
A few cladding conditions that drive backside temperatures to their highest include:
In any of these scenarios, F.A.S.T.’s 240° F rating gives installers confidence that the tape will hold its bond long after the metal panel goes up and the sun starts doing its work.
F.A.S.T. was built to flash and seal. But its aggressive adhesive, durability, and high-temperature performance make it a legitimate multi-tool for the jobsite. Whether you’re seaming over DrainableWrap’s meltshot fibers, protecting a deck’s framing, or installing behind heat-soaked metal siding, F.A.S.T. is engineered to keep up.
