APA certified sub floor

APA certified sub floor

APA certified sub floor

(OP)
Several decades back I had some "Mill" certified plywood go to h*ll on a small personal project. That was when I learned about the American Plywood Association, now the Engineered Wood Association, and the significance, and value of their approval mark.

My daughter is building a house, and the builder is using tongue and groove 3/4 inch AdvanTech subflooring (Aspen OSB) The contract said tongue and grove plywood, but that is kind of aside issue for the moment.

There are No APA markings on the AdvanTech. There is a Proud declarations of Sustainable forest practices, and TECO tested, TECO being a 3rd party testing company, not a mill and process inspecting outfit, as best I can tell.

Lowes and Home Depot have started selling it, with mostly positive reviews, most notably with praise for it's stability and water resistance, even compared to plywood. There are Many Similar positive reviews on some builders' bulletin boards, although it's use seems to be somewhat regional. Some builders say "no way."

- I'm interested in folks' first hand, or reliable second hand experiences with this product.

thanks

RE: APA certified sub floor

I have used Advantech on numerous floors. Commercial to residential. They worked well. I will say i had a problem with a rehab one but the contractor never dried in the building or protected the floor for a full season... that one looked bad and had raised edges, but come on!

I work with an architect that specifies that specific brand for their houses (townhome to mansion size). I figure they got a seminar and some fancy mugs but this has been going on for 10+ years so im guessing they have been performing ok.

Not an endorsement, just some experience.

The framers succeeded in punching two nice rectangular holes in one sheet with the forktruck, and then installed the perforated sheet right in the middle of a bedroom floor. Twice they nonchalantly covered it up with boards etc so the GC didn't see it for a few weeks. I'm not sure plywood would have faired any better.

No timber product can solve those type of issues! :)
