Abstract: An adhesive is applied to a material under compression such that the adhesive penetrates the material when the material is a porous material (e.g., a fiberglass batt). Upon release from being compressed, the material returns to nearly its original size and shape and some of the adhesive penetrates into the material a given distance. Many mats of the material bearing the adhesive at selected locations can be placed on a common carrier for easy dispensing using a dispenser. The common carrier can be refurbished for reuse.

Abstract: A method of making a multilayered insulation product includes applying a retention layer to a first fibrous insulation layer, where the retention layer is porous to enable liquids to pass therethrough, applying a hardenable liquid to the retention layer, where some of the liquid passes through the retention layer and contacts the first insulation layer, and hardening the liquid to bond the retention layer to the first insulation layer. A second fibrous insulation layer can be applied to the retention layer after the liquid is applied to the retention layer, in which case the hardening of the liquid bonds the retention layer to the second insulation layer.
