![]() Best for 10 and 15 MIL vapor barrier films.Use with 10 MIL or thicker vapor barrier for best performance. Specification is provided by manufacturer and is subject to change without notice.īest for taping crawl space vapor barrier, moisture barrier, vapor retarder, vapor barrier for basement, vapor barrier insulation, crawl space moisture barrier. * All values, except when specified as a range, are typical values and may vary within industry tolerances. Vapor barrier sealing tape resists moisture, cold temperature and UV light and conforms to the following specification. This vapor barrier sealing tape is compatible with most polyethylene 10 MIL or thicker vapor barrier films, such as Husky Yellow Guard Vapor Barrier and. vapor barrier sealing tape is made from a cast polyethylene film coated with high tack natural rubber adhesive. Tape down all edges using PERMINATOR TAPE.This heavy duty 9 MIL 4 in. Clean all adhesion areas of dust, dirt and moisture. Cut a piece of the vapor barrier large enough to cover any damage by a minimum overlap of 6″ (152.4 mm) in all directions. In the event that PERMINATOR is damaged during or after installation, repairs must be made. It's highly durable, sticky, insulating, weather and water proof and designed to withstand the most demanding conditions. Wrap around and tape the collar onto the pipe and completely tape fingers to the bottom layer of PERMINATOR, as shown in figure 2. HIGH PERFORMANCE: Heavy duty, commercial grade white vapor barrier tape measures 4in wide x 180ft long and is 9mil thick.With a roofer’s knife or scissors, cut “fingers” half the width of the film. The length should be 1 ½ times the pipe circumference. Cut a piece of PERMINATOR a minimum of 12″ (304.8 mm).To further protect the concrete slab from external moisture sources, use a piece of vapor barrier and place a collar around these as well. Sealing Protrusion s … Cut a slit around pipes, ductwork, rebar and wire penetrations to place the initial layer of the vapor barrier. This will help protect the concrete slab from external moisture sources once the slab has been placed. This will sandwich PERMINATOR between the footing, vertical wall, and poured concrete floor (see illustration below). The most efficient installation method includes placing PERMINATOR on top of the footing and against the vertical wall. Sealing Seams/Attaching to Footing … All joints/seams in the vapor barrier application, both lateral and butt, should be overlapped 6″ (152.4 mm) and taped using PERMINATOR TAPE. Surface Preparation … The PERMINATOR TAPE area of adhesion should be free from dust, dirt, and moisture, to allow maximum adhesion of the pressure-sensitive tape. One box of tape will adhere approximately 10 rolls of PERMINATOR. PERMINATOR TAPE is offered in 4″ (101.6 mm) widths and roll lengths of 180′ (55 m), 12 rolls/carton. The ability of a material to retard the diffusion of water vapor is measured in units known as 'perms' or permeability. The older term 'vapor barrier' is still used even though 'vapor retarder' is more accurate. Maintains a watertight seal in all weather conditions. A vapor retarder is a material that reduces the rate at which water vapor can move through a material.Backing stabilized to resist the effects of UV exposure.PERMINATOR TAPE is for use in sealing vapor barrier seams and attachment to footings, protrusions, etc. PERMINATOR TAPE is a self-adhesive tape, used in conjunction with the application of PERMINATOR underslab vapor barrier.
