Title:
FIRE-RATED STRUCTURAL OSB PANELS WITH OVERLAID WATER-RESISTANT BARRIER
Document Type and Number:
WIPO Patent Application WO/2022/072710
Kind Code:
A3
Abstract:
A wood or engineered wood structural panel, such as, but not limited to, OSB ( "oriented strand board ") or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.
