Trus Joist® TJI® Engineered Wood I Joists

Manufactured by Weyerhaeuser and 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 warping, twisting, and shrinking that can lead to squeaky floors. TJI® joists are light in weight and come in long lengths, which makes them faster and easier to install than traditional framing and saves you both time and money.

For 14 straight years, TJI® joists have been recognized by readers of Builder Magazine as the “most-often-used engineered I-joist.” The results are from a survey of 10,800 builders, builder-developers and general contractors in the U.S.

TJI® joists are an excellent choice for high performance floor designs at a reduced cost.

International Beams (IB) I-Joists

IB I-Joists are light in weight and, therefore, easy to handle. They are strong and span long distances (up to 48 ft.), making them more labour and material cost efficient than solid lumber.

Manufactured to strict tolerances, IB I-Joists are more uniform in strength, stiffer and straighter than cut wood. They are more durable and dimensionally stable and resist splitting, warping, shrinking and twisting that can lead to squeaky floors.

IB I-Joists are the best choice when requiring superior performance under a tight budget.


Engineered Floor Decking

To make the most of engineered floors, Locke Truss recommends engineered sheathing or floor decking as well. By building you floor completely out of engineered components and structures, gives you the the ultimate protection against binding, shifting and warping, virtually eliminating the possibility of squeaks and other anomalies. This helps protect the client’s investment and your superior reputation as a quality builder.
