Grid Style Acoustic Foam Panels - Acoustic Foam Room Kits

They work exactly as described. Put them on the ceiling of my studio. One suggestion would be to incorporate a thin backing for the panels for overhead mounting. Imagine how fast this could be installed if there was a rigid enough back to tag to the wall instead of using alternative spray adhesives or glue based product. Tacks can work but they need to be long enough to hold into the wall without smashing the foam around it warping the pattern. I used tacks double back tape and a few cuss words to get em up, it was a pain but I’m glad they are there!
