TJI joists are lightweight and come in long lengths, which makes them faster and easier to install than traditional framing, and saves you both.

I- Joist Basics I-joists are strong, lightweight, I shaped engineered wood structural members that meet demanding performance standards. I-joists are comprised of top and bottom flanges, which resist bending, united with webs, which provide outstanding shear resistance. An I- Joist is an engineered wood joist , designed to eliminate the problems that occur when using traditional timber joists. The joists are shaped like an “I” and are lightweight, but strong.

It shows the standard span tables for TJI ’s. The tables look overwhelming but they are actually pretty simple to use. I-joists are prefabricated I-shaped structural members that are designed for residential and commercial floor and roof rafter applications.

Their lightweight construction, ease of handling, strength, and ability to span longer distances result in lower overall labor and material costs. At Donaldson Timber Engineering, we design all of our I- joist flooring systems using Finnjoist. I-joists are the most common way to structurally frame an upper floor in a residential building.

I-joists are also commonly used in flat roofs for both residential and commercial buildings. Even more of a savings if you have to return much twisted 2X stock. A deep joist at is usually cheaper than shallower joists at o. I allways glue the sheathing. Red-I joists are manufactured using high-quality, engineered wood—including LVL flanges and RedBuilt’s proprietary OSB web. In addition to the standard parallel flange configuration, some series are available with tapered profiles for added design flexibility.

Trus Joist developed the wooden I- joist 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.
