Abstract: A fibrous insulation product having a plurality of randomly oriented glass fibers and a binder composition that holds the glass fibers together is disclosed. The fibrous insulation product has an R-value in the range of 10 to 54 and, after curing, has a density, when uncompressed, in the range of 0.30 pcf to 2.7 pcf. Furthermore, the fibrous insulation product includes glass fibers that, prior to the application of the binder composition, have an average fiber diameter in the range of 15 HT to 19 HT and a quantity of binder that is in the range of 2% to 10% by weight of the fibrous insulation product. The fibrous insulation product also has an average fiber diameter to density ratio (Fd/D) of less than or equal to 40 and a comfort factor less than or equal to 3.417(Fd/D)+60.

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.
