tectum wall panels

[spiderman2812]

Hey guys, Any one ever hear of tectum wall panels? We're bulding a school an they had some extra 2'x4' sound panels well i guess they are the baffle part. I was going to build a frame and put 3" of mineral wool behind them. I checked the website and all they are are this special made front panel with 1" rigid fiberglass in them The nrc was .75. I got 24 panels for free you can't beat that ! What do you guys think I know there are some pros on here so i thought i would get your opinion. Thanks.

Sounds like you could use them to help trap bass or make a tight spot in the middle of a room. Can't beat free though man, that's cool.
