TJI® Joists

The TJI® joist was developed about 45 years ago and it continues to be a great engineered wood product providing strength and consistency for high performance floor and roof structures. Their dimensional stability helps resist the warping, twisting, and shrinking that can lead to squeaky floors. Because they are lightweight and come in long lengths, they're easier to install than traditional framing. TJI® joists come in different sizes for specific load/span needs. Weyerhaeuser has also produced a new TJI® joist with Flak Jacket® protection. This new technology allows floors built with these joists compliance with 2012 IRC R501.3 and 2015 IRC R302.13.
