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.
