With a goal of balancing breathability with water protection, Fortifiber’s new WeatherSmart Drainable weather-resistive barrier (WRB) uses patented technology to channel liquid away from the wall assembly with better than 95% efficiency. Matching drainage with a perm rating of 15 makes WeatherSmart Drainable useful behind most claddings, including fiber cement, brick, vinyl, and wood siding. The UV-stable material is made from spunbonded polypropylene fabric with a non-perforated breathable polymer layer and embossing for drainage efficiency. The cloth-like, non-woven material resists tears, abrasions, and punctures, and is also designed to provide a reliable air-infiltration barrier. Weather­Smart is priced in line with other premium housewraps. fortifiber.com
