Standard Sheet Sizes/Quality
Standard sheets of foam are cut slightly larger than the listed size to compensate for shrinkage during packaging, transit, and delivery. Sheets may contain rough edges.

The acoustics in my band rehearsal room was horrendous. After a lot of research I purchased 2” eggcrate and corner bass traps from Foam Factory and it made a big difference in sound. Quality product, great prices and fast shipping (arrived earlier than estimated). What more more can you ask for!
Great Store, tyvm

I ordered a 72" x 80" sheet of the 2 and a half inch eggshell foam. It's definitely higher quality than any old foam you might find in a box that something was shipped in. It made a big difference in the sound in my room, it helped cut out the ringing which helped improve the clarity of dialogue. It came in a much smaller package than I was anticipating and it only took about 20 minutes for it to uncompress. Quality product for the best price I found, I will recommend this site to others.
Quality foam

I bought 4 sheets of this egg crate foam to install on the walls and ceiling in my vocal booth. I am very satisfied with the material it was exactly as I expected. Fair price and the packaging was perfect.
Great product!
