The invention is directed to a joint tape for finishing a joint between boards having a nonwoven substrate that does not swell substantially in the presence of water. The invention further provides a method of finishing a joint between boards having the steps of (i) applying a joint tape of the invention to a joint between boards by embedding the joint tape in a first coat of joint compound, (ii) applying a second coat of joint compound over the tape, wherein step (ii) is carried out before the joint tape and joint compound applied in step (i) have substantially dried, and optionally (iii) applying a third fill or finish coat of joint compound over the tape, wherein step (iii) is carried out before the joint tape and second coat have substantially dried.

Glass fiber products, including glass fiber mat and insulation products, are described. A glass fiber mat may include glass fibers and a binder. The binder may include cured products from a carbohydrate binder composition. The carbohydrate binder composition may include a carbohydrate, a nitrogen-containing compound, and a thickening agent. The carbohydrate binder composition may have a Brookfield viscosity of 7 to 50 centipoise at 20? C. as measured with a Brookfield viscometer using spindle 18 at 60 rpm. Glass fiber mats may include a component of a roofing shingle. Glass fiber mats may be a facer, battery separator, a filtration media, or a backing mat.

Soy protein and carbohydrate containing binder compositions are described. The binder compositions may include a carbohydrate, a nitrogen-containing compound, and a soy protein. The binder compositions may also optionally include thickening agents such as modified celluloses and polysaccharides.

A layered composite includes an insulation sheet and at least one scrim layer secured thereto. The at least one scrim layer may be embedded within the thickness of the insulation sheet, or bonded to a corresponding face of the insulation sheet, and have a tensile strength greater than that of the insulation sheet. As such, the scrim layer provides structural support to the insulation sheet as well as a trap for fibers or particles that may separate from the insulation sheet.

The invention is directed to a joint tape for finishing a joint between boards comprising a nonwoven substrate that does not swell substantially in the presence of water. The invention further provides a method of finishing a joint between boards comprising (i) applying a joint tape of the invention to a joint between boards by embedding the joint tape in a first coat of joint compound, (ii) applying a second coat of joint compound over the tape, wherein step (ii) is carried out before the joint tape and joint compound applied in step (i) have substantially dried, and optionally (iii) applying a third fill or finish coat of joint compound over the tape, wherein step (iii) is carried out before the joint tape and second coat have substantially dried.
