Your floors are only as good as what's underneath them, and we stock the best: AdvanTech subflooring.

It's a step up from standard OSB and plywood. Builders have voted it #1 in quality every year since 2002, and once you use it you'll understand why.

Here's what makes it stand out:
- Moisture-resistant resins go all the way through the panel, so there's no swelling, warping, or delamination even after a rainy stretch on the job site
- Superior fastener holding power keeps floors flat, stiff, and quiet
- Precision tongue and groove panels fit together tight and install fast

Need 1 sheet for a small repair or 100 for a full build? We can handle either. Stop by the yard and we'll get you exactly what you need.
