Moistop PF® is the solution of choice when building requirements call for a mechanically-attached flashing product that is unaffected by substrates or job site conditions. Manufactured from a multi-layer composite employing heavy-duty polypropylene woven fabric, and coated on both sides with ultraviolet-resistant polypropylene, the product resists cracking and curling – both before and after installation. Moistop PF’s unique construction makes it ideal for installation over OSB or plywood, making it easy to integrate with a weather-resistive barrier. It can be used on all types of windows, including wood, vinyl and aluminum casing – as well as doors. The product is available in pre-cut widths of 6, 9, 12 and 18 inches, and installs easily with a utility knife and hammer. Part of the Fortifiber® 1-2-3 moisture control system, Moistop PF is designed to withstand the rigors of the jobsite and the elements and is backed by a 15-year warranty.
