I Joist Roof System

An introduction to best practices in the design of engineered roof systems.

I joist roof system.

I joists are used extensively in residential floor and roof framing. Build sturdy stable floors with wider flanges. I joists provide a high performance alternative to dimension lumber joists for floor and roof applications. Because i joists are straight and true it s easier for builders to avoid crowning and maintain a level framing surface.

We can offer cost saving flooring and roofing solutions to a range of public and private sector applications. I joists are quality materials used to build engineered roof systems timber floors and walls. Tji joists are lightweight and come in long lengths which makes them faster and easier to install than traditional framing and saves you both. Instead a wood i joist roof system is framed with either a central bearing wall or a structural ridge a beam that carries the roof load to posts.

The bottom half is carried by the exterior bearing walls. Complete instructions on placing second floor beams and for post and beam roof systems. The i joists can wrap twist shrink and consists of slow grown high grade white wood flanges. The load from the top half of the roof is carried by the bearing wall or structural ridge.

The dimensional stability of tji joists help them resist warping twisting and shrinking that can lead to squeaky floors. They can be trimmed on site and long lengths allow ceilings and floors to be designed with fewer pieces saving installation time. Shall be permitted to be used. Lp solidstart i joists are more versatile than open web floor trusses and more uniform and dimensionally stable than lumber.

Trus joist tji joists are a key part of making a high performance floor. I joists whether you are constructing a floor ceiling wall or roof the steico system provides a total building solution. 2 0 maximum cantilever roof truss span 2 0 maximum cantilever hip girder trusses truss roof trusses 13 0 maximum roof truss span. These are the right choice for both residential and non residential floor and roof joist construction.

For hip roofs with the hip trusses running parallel to the cantilevered floor joists the i joist reinforcement requirements for a span of 26 ft. 2nd floor joist 3. Post beam roof support 7.
