Done right, no. I built a glass box for my 2 12"s. It's less than 1/4" thick, sealed, and seeing about 800 rms and I'm having no problems. And to be perfectly honest I did a pretty shitty job on the glass work. If you take your time and get all the air bubbles out I think it would work fine, even with the w7.
