Wood I-Joist

Wood I-Joists

I-Joists are the ideal choice for high quality residential floor systems. They offer designers and builders consistent performance for the most demanding floor plans.

The longer length I-joists give designers the freedom to design more open space into their projects, reducing the need for supporting walls, columns, and beams.

Builders like I-joists because they allow multiple span installations without the need to lap joists over bearing walls or support beams-saving time and money. Webs are easily cut onsite for mechanical pass through. There are fewer pieces to handle, and the I-Joists can be cut and fastened with traditional framing tools and fasteners. Plus, they weigh much less than comparable conventional lumber.

Framers appreciate the extra-wide nailing flange; 2-1/2“ or 3-1/2“, compared to other manufacturers’ 1-1/2“ width.

I-Joists won’t warp, twist, or shrink, and offer more uniform dimensions than sawn lumber joists.

Allstate Builders uses I-Joists and Straight Laminated Columns.

Product Warranty

All I-joists are guaranteed to be free from manufacturer’s defects or errors in workmanship and material in accordance with our specifications. We further guarantee that these products when correctly installed, will meet or exceed their design specifications for the normal life of the structure.

All I-Joists are produced in accordance with American Plywood Association (APA) and Engineered Wood Association (EWS) Performance Rated I-joist Standard that was introduced in 1997. The APA/EWS standard provides a span rating system for I-joists used in residential construction. All APA Performance Rated I-joists, or PRIs have common load/span tables, uniform rules and guidelines for installation, and consistent engineering design values. Span ratings are stamped right on the product; making it easy to install properly, and for code officials to inspect. The stamp tells how far the joist will span at a given spacing for uniform load applications.
