Engineered Floor Systems:

Trus Joist developed the wooden I-joist 50 years ago and Weyerhaeuser continues to build on that legacy. Engineered to provide strength and consistency, these joists are a key part of making a high-performance floor. The dimensional stability of Trus Joist TJI joists help them resist the warping, twisting, and shrinking that can lead to squeaky floors. TJI joists are light weight and come in long lengths, which makes them faster and easier to install than traditional framing and saves you both time and money.
