Abstract
A fibrous insulation product comprising a plurality of randomly oriented glass fibers and a cross-linked formaldehyde-free binder composition at least partially coating the fibers is disclosed. The cross-linked formaldehyde-free binder composition is formed from an aqueous binder composition comprising 5.0% by weight to 37.0% by weight of at least one monomeric polyol having at least four hydroxyl groups and at least 50.0% by weight of a cross-linking agent comprising a polymeric polycarboxylic acid having at least two carboxylic acid groups, based on the total solids content of the aqueous binder composition. The glass fibers have an average fiber diameter in the range of 8 HT to 12 HT. The fibrous insulation product, after curing, has a density, when uncompressed, in the range of 0.30 pcf to 2.7 pcf.
