I-Joists (PRI) are manufactured to specific dimensions commonly used in residential construction.

We offer a PRI 40, 60, and 80 series I-Joist in 9-1/2”, 11-7/8”, 14”, and 16” depths.  Also available is an 18" I-Joist that is a custom order but can be easily filled.  Newly added to our I-Joist family is the APA PRI 20 Series I-Joist, available in 9-1/2", & 11-7/8" with a 1-5/8" flange width.

Why use I-joist over solid sawn timbers?

I joist are more economical for the environment. I-Joist uses 50 percent less wood fiber than typical solid sawn 2x10’s or 2x12’s.

I-Joist also provides a stronger and quieter floor. This can be accomplished because each joist is made the same every time. Using solid sawn 2x10’s or 2x12’s every piece is not made the same which can be cupped, warped, and twisted. This makes for squeaky and un-even floors.  

The APA Mark of Quality

APA trademarks appear only on products manufactured by APA member mills. The mark signifies that panel quality is subject to verification through APA audit– a procedure designed to assure manufacture in conformance with APA performance standards or the standard shown in the mark.
