Flak Jacket protection from Weyerhaeuser

Weyerhaeuser's Trus Joist TJI joist line is now available with the company's Flak Jacket coating that enhances fire resistance. This new TJI joist option provides builders with a simple, cost-effective way to achieve one-hour floor/ceiling assemblies and to comply with the new 2012 IRC fire protection requirements.

For instance, in multi-family buildings, TJI joists with Flak Jacket protection provide a one-hour fire-rated assembly with only a single layer of gypsum and no expensive mineral wool. The product is durable and does not require special tools or training to use — builders can cut and drill the joists as usual, and use standard hangers for quick and smooth installation.
