Fire-Resistant Joists
TJI Joists are now available with a new fire-resistant solution called 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 fire protection code requirements. Flak Jacket protection helps solve the challenge of shifting code requirements while providing quality and cost efficiency, allowing buildings to achieve a one-hour, fire-rated assembly with just a single layer of gypsum and no expensive mineral wool.
