Abstract: The present invention relates to a method for improving the thermal performance of fibrous glass insulation in the admix recycling of the insulation, which includes the use of corrugated hose in the recycling process.

Abstract: A method for adhering together lanes of a compressible product includes inserting a wedge device between two separate lanes of a compressible product to split apart at least a portion of the lanes of product, advancing either the wedge device or the separate lanes of the compressible product to move the wedge device and lanes relative to one another, applying an adhesive onto an inside wall of one or both of the lanes of compressible product while at least a portion of the lanes are split, and contacting the inside walls of the lanes to form a single adhered product.

Abstract: A method of insulating ducts is described including laminating a reinforcement fabric to a fibrous insulation board, lifting at least a portion of the reinforcement fabric from the fibrous insulation board, applying a first layer of a mastic coating to the fibrous insulation board, embedding the reinforcement fabric into the first layer of mastic coating, and applying a second layer of the mastic coating to the outside surface of the reinforcement fabric. The reinforcement fabric is laminated to the fibrous insulation board using an adhesive material.

Abstract: Water resistant fibrous air duct insulation products and methods for making such products. The products may include a duct board or a duct tube including a plurality of layers of resin-bonded fibrous mat. The duct board or tube is preferably rendered water-repellent at the air stream surface by incorporating a hydrophobic agent into the resin of at least one of the layers adjacent the air stream surface.

Abstract: Flame-resistant insulation may be prepared by coating a glass fiber substrate, such as a fiberglass board, with an aqueous dispersion of vermiculite and expandable graphite. The insulation may also be pre-coated with a vermiculite dispersion prior to coating with a vermiculite/expandable graphite coating, and the vermiculite/expandable graphite coating may be covered with an FSK facing, or with a gypsum or portland cement layer. The resulting coated insulation board has superior flame resistance, and may be used as a component of a building or in vehicles.

Abstract: Water-resistant fibrous air duct insulation products and methods for making such products. The products may include a duct board or a duct tube including a first layer of resin-bonded fibrous mat having a second layer of durable, preferably non-woven, facing material adhered thereto, wherein the facing material defines the air stream surface for the board or tube. The duct board or tube is preferably rendered water-repellent at the air stream surface by incorporating a hydrophobic agent into the adhesive used to adhere the second layer to the first layer.

Abstract: A device and system for securing adjacent segments of duct work formed from fibrous glass duct board insulation and the like is disclosed. The device comprises a corner member having two legs disposed at approximately right angles, each of said legs having oppositely facing and substantially parallel adjacent channels disposed therein to accommodate portions of opposed edges of adjacent segments of duct work. The system includes a plurality of corner members each having two legs disposed at approximately right angles, said legs having substantially parallel and oppositely facing adjacent channels disposed therein to accommodate at least a portion of the opposed edges of adjacent segments of duct work.

Abstract: Encapsulated glass fiber insulation includes a non-woven covering material over the top surface of a mineral fiber core, with the formed covering material extending adjacent the side surfaces. The covering material is greater in width than the sum of the widths of the top and two side surfaces, so that the edges of the formed covering material extend beyond the mineral fiber core.
