An electrical insulating sheet is disclosed. The sheet includes 50-99% D glass flakes and 1-50% additives. Optional ingredients include a bonding agent, porosity control agent, and reinforcing agent(s) to enhance tensile strength.

A hip and ridge shingle includes a base sheet having colored granules adhered to the top surface. A chip is adhered to the base at the trailing edge of the base sheet. A sealant bead is provided parallel to and adjacent the leading edge of base sheet.

A baffle adapted to be rolled with a ridge vent is comprised of an L-shaped configuration having first and second legs. The first leg is adapted to extend under the ridge vent. The second leg is adapted to be oriented at an angle relative to the first leg and some distance from the ridge vent when the baffle and the ridge vent are installed. The first leg is also adapted to be rolled. The second leg is adapted to collapse when the first leg is rolled. The invention is also directed towards a ridge vent in combination with the baffle and a method for forming the baffle.

Rollable baffle and ridge vent

A fire resistant thermosetting resin composite formulation comprising an effective amount of a flame suppressant additive. The thermosetting resin used in the formulation can be a polyester resin. The flame suppressant additive is a polyvinyl chloride powder which may be obtained as a reaction product of an emulsion polymerization, or alternatively, it may be obtained from recycled products containing significant amounts of polyvinyl chloride. The additive can be used in an amount of from 1% by weight to about 75% by weight based on the amount of an inorganic filler material that may be present in the formulation.

A system is provided for forming a continuous mineral fiber wool tow and cutting the tow into discrete lengths. The system comprises a conveying apparatus for pulling a mineral fiber wool tow from a mineral fiber pack at a first location and transporting the tow to a chopping station. A chopping apparatus is positioned at the chopping station for chopping the tow into discrete lengths. The conveying apparatus further receives the discrete lengths at the chopping station and transports the discrete lengths to a collecting station. The conveying apparatus further includes a collection device located at the collecting station for receiving the discrete lengths of mineral fiber wool material and collecting the discrete lengths for subsequent use.

System for forming and cutting a mineral fiber tow

An irregularly shaped glass fiber is provided which enjoys improved resiliency, and openness in pack structures. Wool packs and other wool portions having such irregularly shaped fibers may be processed directly through needling to form a non-woven material without intervening steps such as carding or blending of fibers which accompany conventional glass fiber processing operations. In a further aspect of the invention, a non-woven material including irregularly shaped fibers in a generally continuous wool tow is produced by 'unwinding' a fiberglass wool pack collected by a direct forming method. Product applications include simplified, lower cost processing, and new uses of the irregularly shaped fibers produced by rotary fiberization in filtration elements, sorbants, gaskets, packings, shingles, composite structural elements, furnishings, textiles, yarns, and blown-in insulation systems.

A facer sheet is provided which is adapted to receive a prefoam mixture during a structural laminate forming process. The facer sheet comprises a first predominantly glass fiber mat having first and second outer surfaces and a polymeric material applied to the first outer surface of the mat. The polymeric material acts as a substantially impervious barrier to the liquid prefoam mixture received at the second outer surface of the mat during the structural laminate forming process.

A facer sheet is provided which is adapted to receive a prefoam mixture during a structural laminate forming process. The racer sheet comprises a first predominantly glass fiber mat having first and second outer surfaces and a polymeric material applied to the first outer surface of the mat. The polymeric material acts as a substantially impervious barrier to the liquid prefoam mixture received at the second outer surface of the mat during the structural laminate forming process.

Method for producing non-woven material from irregularly shaped glass

A foam facer mat incorporates a natural short wood pulp fibers to provide dimensional stability to foam insulation for roof insulation. The facer mat also employs chopped glass fibers with the wood pulp.

Fibrous mat with cellulose fibers having a specified Canadian Standard

A glass fibrous mat is disclosed which includes a blend of fibers comprising approximately 70-90%, by weight 6.5-13.0 micron in diameter wool fiber and approximately 10-30%, by weight, 7.5-13.5 micron in diameter, 1/8 to 1/2 inch in length textile glass fibers bonded together with a resin, binder material comprising a melamine cross-linked styrene-butadiene resin. The glass mat has been found to be highly satisfactory for use as an interlayer for compressible vinyl floor coverings.
