Manufacturing Tolerances
Products may carry a size tolerance depending on the style and job. Please see our Tolerance Table.

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. Any yellowing/discoloration present is a byproduct of exposure to light during production and manufacturing and does not represent a flaw, damage, or defect in the material.

Good Stuff

This was nicer material than I was expecting. Its really soft and cuts well, the actual size for my 'full size' sheets was about 77'' x 83''. Its considerably nicer than the existing foam I was salvaging from my last project. I specifically bought full size sheets of the 1.5'' 'acoustic' eggshell charcoal foam.

Excellent. Not one single complaint. I will definitely be shopping with Foam Factory again.

Ordered a total of 5 pieces and they all came in a nice vacuum sealed bag nicely packaged. Let them fluff out for a couple days and they were literally perfect. Nice and thick, very very few tiny defects if any at all on most pieces, and easy to resize with a sharp razor. Best way to cover entire walls with acoustic foam 10/10 would recommend. Only thing is to make sure you have a proper method of hanging them as they are heavier then the overpriced 1’x1’ panels on Amazon. I used a combination of a staple gun along the top and heavy duty spray tack/glue for most of the rest. When using spray tack first coat the wall and back of foam and let dry then apply second coat as you’re hanging it up since it doesn’t have a lot of grip on the first coat but second coat seems to stick very well
Great Foam for sound insulation

Used it on a boat engine cushion lid to reduce sound coming from motor.
