Wasnt what I was expecting but perfect for what I needed. I was trying to cover a bunch of pipes and electric and just ugly ceiling stuff and these worked perfectly because they have a little give. I will say though that I didnt glue them. I ran 2x4s doing the ceiling and stapled these in, then just painting over the staples. Oh, I also painted them with just white flat paint and you cant even tell theyre styrofoam now!
