The primary cause of water intrusion into a commercial or residentialbuilding is the lack of properly integrated flashing around windows,doors and other fenestrations. The cost of these repairs and potentialexposure to litigation can be staggering, particularly when water leakageleads to problems with mold and mildew.

To prevent water leaks, windows must be installed with a sealant that iscompatible with all the different components that must work together.

This has been validated throughextensive third party ASTM testing,as well as field verification ofindividual system components by theFortifiber Building Systems Group®.The results of these tests leave nodoubt that the proper selection and installation ofsealant and flashing are essential to theelimination of water leaks through windows anddoors.

Completely Compatible, Moisture Resistant SealantMoistop Sealant is a quality sealant that is designed to be compatible with virtually allbuilding materials, as well as wood, vinyl and aluminum flanges, Jumbo Tex®

building paper, PlyDry®, WeatherSmart® and all Fortifiber flashings. It is the mostlogical choice for window and door installations and a variety of other buildingapplications. Moistop Sealant delivers excellent adhesion, compatibility, durabilityand moisture resistance to prevent water leaks and the expensive callbacks they cause.It is also suitable for use in construction joints up to one half inch in width.

Exceeding ASTM C-920 and AAMA 808.3-92 (Exterior Perimeter SealingCompounds) standards, Moistop Sealant makes it easy to get extraordinary resultsfrom an ordinary caulking gun. A continuous bead on the window nail flange giveslong lasting protection against moisture infiltration. And even though MoistopSealant is tough enough to repair torn vapor barriers, it is smooth enough to takepaint in visible application areas.

Part of a Complete Moisture Control SolutionMoistop Sealant, combined with the extensive line of Fortifiber flashing products –integrated with a Jumbo Tex, PlyDry or WeatherSmart weather-resistive barrier –forms a comprehensive weatherization system that protects homes and buildingsagainst moisture intrusion problems. Designed through the use of building scienceand perfected in the field, this is the only complete moisture control system availablein the industry from a single source.
