TJI® joist, the number one brand in the industry, is available with a new fire-resistant solution called TJI® Joists with Flak Jacket™ protection. Flak Jacket protection is a proprietary, patent-pending coating that enhances the fire resistance of TJI Joists and enables them to meet both single and multi-family fire protection code requirements. Flak Jacket protection helps solve the challenge of shifting code requirements while providing all the quality and cost-efficiency you expect of Trus Joist engineered lumber products.
Achieve a one-hour fire-rated assembly with just a single layer of gypsum and no expensive mineral wool. New TJI Joists with Flak Jacket protection save you time, maximize labor, reduce costs and complexity, and enable faster, more efficient construction.
Like all TJI Joists, no special tools, training or handling are required; you can cut and drill the joists as usual and use standard hangers for quick and smooth installation. TJI Joists with Flak Jacket protection deliver Weyerhaeuser quality and reliability backed by our service and support.
