I’m not adept in acoustic room treatment or fiberglass but I’ve done my research to try and build my own acoustic panels as the country I live in does not have any readily available. Fiberglass was the only effective material available where I live, with only one retailer for a decent price. I opened the packaging today and expected the fiberglass to fold out like I’ve seen on the manufacturers YouTube channel but that wasn’t the case. It wasn’t as rigid as I thought it would be so I ended up stapling the edges of the insulation to the frame. It looks a bit off color also but I’m not sure if that is how it is supposed to be or if the quality isn’t good. I have a picture of the panel I stuffed. Not currently at the wood shop where I left them so if another picture is needed I can send tomorrow. Please take a look and give ur opinions please.

If you don't compress the fiberglass you should be OK
