Axiom Home Page Forums General Discussion Home Theater Looking for some feedback on HT room design.

Were you looking at the Delta-fl product? I know there are other options like dri-core but the Delta-fl was the most affordable one I found. 1/2 OSB is about $7 for a 4x8 sheet around here. I did spend about $100 in tapcons, and that's where all the labor is, drilling and screwing it all down.

We get robbed on stuff up here, although I was looking at the Delta FL and going with T&G 3/4" flooring to really stand up to the wear and tear a floor takes. I find 1/2" to weak and flexes to much unless I took the time to level the concrete.

If you screw thru the flooring doesn't that kind of give moisture a way to bypass the Delta FL and reach the back of the wood sub flooring? I thought it was to be set up as a "floating floor" like the dri-core stuff.

No this is not a floating system. The instructions tell you to put silicon on the tapcons before you screw them in. They also say to use low expansion foam around the edge if you are butting the floor up to an existing wall.

My concrete is pretty flat so I have no worries about using 1/2 inch. The instructions say you can use as skinny as 7/16 if you want to.

Thanks for the added info.
