Key Features and Components of ZIP System ® Sheathing and Tape 1 High quality structural sheathing panel made of engineered wood delivers strength and durability. 2 Built-in vapor permeable water-resistive barrier eliminates the hassles of house wrap and felt. Engineered for enhanced drainage of bulk water and optimal permeability to allow water vapor to pass through and promote drying. 3 A continuous, rigid air barrier decreases unwanted air leakage for greater energy efficiency. 4 ZIP System ™ tape with a specially engineered, high performance acrylic adhesive bonds with ZIP System ® panels for a permanent protective seal. 1/2' & 5/8' ZIP System ® Roof & Wall Sheathing Performance Category Panel Size Panel Count Edge Profile PS2 Span Rating Code Evaluation Report Vapor Transmission of WRB Layer** 1/2 4' x 8' 70 T&T 32/16 Structural 1 ESR 1473 ESR 1474 12-16 perm ASTM E 96-00 Procedure B 5/8 4' x 8' 55 T&T T&G* 40/20 Structural 1 *Contact your Huber Sales Professional for availability in your area. **When used with ZIP System ™ tape Although all projects are unique, experience has shown that 1 roll of 3 3/4-inch ZIP System ® tape is needed for approximately 7 sheets of 4x8 ZIP System ® sheathing. This should only be considered a general 'rule of thumb' when ordering materials with the understanding that some jobs may require more or less depending on the specific project. UPDATED March 8, 2013 After this article was published, Martin Holladay conducted a test of eleven air-sealing tapes on a variety of materials. To read the results of Holladay's testing, see and. It’s hard to create a tight air barrier Building assembly components that work as a system to restrict air flow through the building envelope. Air barriers may or may not act as a vapor barrier. The air barrier can be on the exterior, the interior of the assembly, or both. Without using tapes, gaskets, caulk, or spray foam. In this blog, I’ll look at two of these categories — tapes and gaskets. I’ll be focusing on air-sealing products, so I’ll ignore flexible flashing tapes used for waterproofing. (I'll address duct sealing in.) [Author's note: since this blog was originally published, two U.S. Distributors have begun selling high-quality European construction tapes. While these tapes tend to cost more than tapes from U.S. Manufacturers, most builders who have tried them have been impressed with their performance. Moreover, European tape manufacturers (unlike U.S. Manufacturers) offer tapes that are vapor-permeable. The two distributors are of Olympia, Washington (distributor of several types of Siga tape, including Corvum, Rissan, Sicrall, and Wigluv tapes) and of Brooklyn, New York (distributor of Contega tape, Tescon tape, Unitape, Rapidcell tape, and Budax Top tape).] I’d like this blog to be a work in progress, so I strongly urge readers to post information on products that work well. A multitude of tapes To limit air leakage, builders use tapes to seal the seams of a variety of membranes and buildings products, including housewrap, polyethylene, OSB, and plywood. Tapes are also used to seal duct seams, to seal leaks around penetrations through air barriers — for example, to seal around plumbing vents — and to seal sheet goods Material, usually plywood or oriented strand board (OSB), but sometimes wooden boards, installed on the exterior of wall studs, rafters, or roof trusses; siding or roofing installed on the sheathing—sometimes over strapping to create a rainscreen. To a variety of materials, including concrete. RELATED ARTICLES Needless to say, no single tape works well in each of these applications, so builders need to familiarize themselves with a range of products. Sealing seams in housewrap or Tu-Tuf Lots of manufacturers make housewrap tape. Manufacturers include 3M (), Berry Plastics (, ), Dow (), DuPont Tyvek ( — formerly sold as “Contractors' Tape”), Johns Manville (), Typar (), and Venture (). Venture tapes are available from Maine architect Jesse Thompson has high praise for Dow Weathermate tape; according to Thompson, it has a “good and strong adhesive, and is readily available.” Most housewrap tapes work well to seal seams in Tu-Tuf ground covers.
