"Extract" fiberglass is one of the most widely used paint overspray collection media due to its cost effectiveness and versatility. Our fiberglass is 2" thick and is specifically formulated for high paint holding capacity. Fiberglass stores compactly so that a 300 foot roll only has a 24" diameter. Extract fiberglass is available in 300' bulk rolls only, minimum order of 6,000 square feet for multiple sizes.
