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.
