Barrier & LP Talk III-A Walls with Engineers, Architects
Barrier National Sales Manager
The U349 wall assembly is an exterior, wood-stud limited load bearing wall rated two hours for interior fire exposure. It features two layers of Type X gypsum on the interior face, 2x4 or 2x6 fire-retardant treated wood studs and FlameBlock 2-sided (coated on both faces of the OSB) on the exterior. The two-sided FlameBlock product replaces two layers of Type X gypsum on the exterior face of the wall (see GA WP 4136 for a representative two-hour assembly featuring four layers of Type X gypsum) and offers both structural strength and fire protection in a single panel.
The early May meetings were hosted by Cates Engineering, which has studied the use of wood-frame construction in multi-story residential, commercial and mixed-use construction for several years. Cates has, in fact, produced a packet that details structural engineering concerns around five-story wood construction. Developers and architects looking to capitalize on the use of the U349 wall assembly to shave construction costs and time, and/or allow for a larger footprint or additional height on suitable Type III-A construction, are encouraged to contact Barrier for more information and a referral to Cates Engineering.
Barrier will also be participating with LP in the Hospitality Design Expo in
Two-sided FlameBlock is being used on the exterior walls of this Type III-A mixed use building.
The U349 wall – with two-sided FlameBlock -- has been specified in a 400,000 square-foot student housing complex on the East Coast; keep an eye on our blog for details about this project as it gets built this summer!
