Great floor

“I bought a few months ago for my new house flooring and I’m happy so that I did. Its dense construction reduces impact noise and those annoying gaps between trim and flooring by raising the subfloor .
Also increasing floor stability and minimizing flex between planks to make floors solid and comfortable under each step.Waterproof and protects from harmful moisture”

Super Easy installation

Oh, I really liked the Quietboard underlyament. It was very easy to work with and I thought the installation of it was far quicker than the last time we did it. Last time it took us maybe 6 hours and this time, not so long. Loving the quiet steps!!! It’s thicker than most of the others, and I think that’s what gives Quietboard the edge over the others.
