1DO I INSTALL ZIP SYSTEM SHEATHING LIKE REGULAR SHEATHING?
Yes. Install the ZIP System sheathing like regular structural sheathing. The panels can be installed horizontally or vertically, and the green Stormex water-resistive barrier should face the outside of the house. For ease of installation, a fastening guide for internal fastening is pre-printed on the panels for horizontal and vertical installation. Note: Tighter o.c. fastening may be required by design documents, or local code jurisdictions. Refer to local code, design documents or local jurisdictions for perimeter fastening requirements.
2Can I Cut and Install ZIP System Sheathing Like Traditional OSB and Plywood?
Yes. You can cut ZIP System sheathing panels just like conventional OSB or plywood. The protective moisture barrier is built into the panels; it won’t crack or break off with cutting.
3How Many Rolls of Tape Do I Need?
Although all projects are unique, experience has shown that 1-roll of tape is needed for approximately 7-sheets of 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 specific project.
4Do I Need to Tape All of the Seams Between the ZIP System Sheathing Panels?
Yes, in order for ZIP System sheathing to function as a roofing underlayment when used on the roof or as a water-resistive barrier and air barrier on the walls, all panel seams must be taped with ZIP System Tape.
5Can Tapes Other Than ZIP System Tape Be Used to Seal the Seams Between the Panels?
No. Only ZIP System Tape should be used with ZIP System sheathing. ZIP System Tape is specially formulated to work with the ZIP System sheathing. ZIP System tape is the only tape that is code-recognized for use with ZIP System Sheathing.
6Can ZIP System Tape Be Installed in Cold Temperatures?
ZIP System tape should not be installed when the temperature of the tape is below 20 degrees Fahrenheit (-6.7 degrees Celsius.
7Can I Use Staples to Fasten Panels?
If the authority having jurisdiction (building official, building code, architect or engineer) allows the use of staples to install typical wood structural sheathing on the roof or wall, then yes, staples are acceptable to be used to install ZIP System sheathing.
8Can ZIP System Tape Be Installed in the Rain?
The surface of the ZIP System sheathing shoud be dry to the touch with not standing water or frost prior to tape installation.
9How Do I Install ZIP System Tape?
The ZIP System tape gun or ZIP System tape roller are specially designed for ease of tape application and can be purchased at your ZIP System wall retail locations. The gun and roller not only makes tape application fast and easy, it also provide a high quality tape seal.
10What fasteners should I use on ZIP System panels if I am installing a metal roof?
Metal roof coverings may be applied to ZIP System sheathing provided roof covering manufacturer's installation instructions are followed. Fasteners used to secure the ZIP System sheathing panels to supporting framing must be compatible with the specific metal roof covering used. Galvanized fasteners shall be used with galvanized roof coverings, aluminum-zinc coated fasteners shall be used with aluminum-zinc coated roof coverings, and three hundred series stainless steel fasteners shall be used with copper roofs. Stainless steel fasteners are acceptable with all metal roof types. In addition, metal roof flashing shall also be made of a material compatible with the specific metal roof covering used.
11Do Fastener Heads Need to Be Taped Over?
Overdriven fasteners do not necessarily void the ZIP System® sheathing warranty. However, when a fastener misses the framing and results in a “shiner” or if a fastener penetrates roughly half way or more through the panel, steps must be taken to seal these penetrations. Shiners should be removed and holes should be covered with ZIP System™ tape or ZIP System™ liquid flash. Fasteners that penetrate roughly half way or more through the panel should also be covered with tape or liquid flash.
