Henry Moistop PF® Flashing

The primary cause of water intrusion in a commercial or residential building is the lack of properly integrated flashing around windows, doors and other fenestrations. When the flashing fails, the cost of repairs and potential exposure to litigation can be staggering – particularly when water infiltration leads to problems with mold and mildew.

Moistop PF® is a critical element in the complete Moisture Control System for Walls pioneered by the Fortifiber Building Systems Group®. The product is engineered to answer the need for a mechanically- attached flashing material that offers a unique balance between extraordinary durability and cost-effectiveness. Moistop PF resists extreme jobsite abuse – such as heavy wind and rain – while effectively containing costs and protecting structures.

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 installs easily with a utility knife and hammer.
