Abstract: An insulation product is disclosed that includes a plurality of glass fibers and a cross-linked formaldehyde-free binder composition at least partially coating the glass fibers. The glass fibers have an average fiber diameter in the range of 8 HT (2.03 ?m) to 15 HT (3.81 ?m). The insulation product is structured such that at least 30% by weight of the glass fibers in the insulation product are oriented within +/?15° of a common plane defined by a length and width of the insulation product. The insulation product has a density, when uncompressed, between 0.2 pcf and 1.6 pcf.

Abstract: An insulation product with an improved material efficiency is disclosed comprising a plurality of glass fibers and a cross-linked formaldehyde-free binder composition at least partially coating the glass fibers. The glass fibers have an average fiber diameter in the range of 8 HT (2.03 ?m) to 15 HT (3.81 ?m). At a density (x) between 0.2 pcf and 1.6 pcf, the insulation product may achieve a material efficiency (y), expressed as R·ft2/lb, that meets or exceeds a value (y) that satisfies Formula (VII): y=40.1916068x2?120.5813540x+129.628397??Formula (VII) .

Abstract: An insulation product is disclosed comprising a plurality of glass fibers; and a cross-linked formaldehyde-free binder composition at least partially coating the glass fibers. The glass fibers have an average fiber diameter in the range of 8 HT (2.03 ?m) to 15 HT (3.81 ?m). At a density (x) between 0.3 pcf and 1.6 pcf, the insulation product may achieve a thermal conductivity (y) less than or equal to that which satisfies Formula (III): y=0.116x2?0.3002x+0.4219.
