good product

I am glad I opened the package and started calculating the layout of the panels in the given space rather than just taking them out and starting to cut on them. I discovered that the dimensions represented in the item information are not accurate or correct. The space that was constructed was laid out to standard construction dimensions with 16 1/2 inch centers for fastening to the wall studs. once I began laying out and measuring the panels, I discovered that they are not true 24 x 48 dimensions as represented in the product description. Both dimensions are less than what is stated and clearly will not fit standard construction dimensions, so I am left without the product that I needed and was planning on installing. Back to the drawing board but unfortunately, the expense has been incurred to construct the space that they are to fit in.

I ordered two boxes and thankfully the sizing was the same on both but both are smaller than advertised. They are 47.25 X 23.5 inches. This threw off my layout to fill the wall fully and left an unexpected gap on the side and the top. They also barely adhered to 3M stickers.

Really good quality and look great on my wall. I was sound proofing my upholstery studio and used these in combination with other measures and worked great

Not sure they work. Look okay though on the wall.s.
