I am looking for a floor joist with no OSB in it. Plywood

Customer Question

I am looking for a floor joist with no OSB in it. Plywood throughout. Is there such a product on the market? I cannot seem to find one - they all contain OSB or some similar piece in the middle.
Thanks,
Leanne.

What depth and span are you looking for?

Ok. What are my options ? I am looking for solid wood joists but every time i search it comes up w osb or some strand board option
Expert:  walkereng replied 3 months ago.

In general, the webs of the engineered lumber I-Joists are made of OSB.

There are numerous APA publications that reference using plywood as a web material, but I do now think that is happening any longer.

What is your need to have plywood webs? Are these going to be exposed to weather?

Customer: replied 3 months ago.
I prefer them to osb. Also I believe wood has more fire retardant potential. Yes I was able to also locate the apa statement that plywood is used - but unable to locate an actual product

I can do a bit of research for you today and let you know what I find.

There are approximately 9 manufacturers of I-Joists that I can research.
