iLevel by Weyerhaeuser. ILevel Shear Brace has received ICC-ES 2009 IBC/IRC code compliance verification. Unlike steel prefabricated shear panels, Shear Brace can be field-trimmed allowing builders to customize the material to fit, despite uneven foundations and varying wall heights. The engineered panels can be used to create walls up to 20 feet high, including two-story structures. Shear Brace can be nailed and further simplifies work for trade contractors by providing pre-drilled chases and holes for wiring and lights. 888.453.8358. www.ilevel.com.
