Acoustisorb glued to masonite?

Hi everyone, First time poster here. Just wanted to ask a quick question. I bought myself some rockwool (acoustisorb 3) and I am about to build my panels, and was wondering what you guys thought about a possible way I had planned to do it. I was planning to cut the rockwool to size (1.2 x 600m x 50mm) and glue them directly to masonite sheets, then put fabric over them. I would then just hang them like a picture frame to the wall. The practicality of this is that masonite is cheap, lightweight and it saves time building frames etc. Just wondering what the possible issues of going about this way might be. Cheers.

Hi "Alfo". Please read the forum rules for posting (click here). You seem to be missing a couple of things! :) Your plan would work, but it does mean that there is no air gap behind your panel, so you are limited to only the thickness of the mineral wool. If you leave an air gap behind, then that extends the range of absorption down to lower frequencies: With a solid back, you would not get that extra effect. But apart from that detail, it would be fine. - Stuart -
