Abstract: Batt style insulation comprised of cellulosic and thermoplastic material and a method of making such insulation. A blend of cellulosic material and thermoplastic fibrous material, wherein the latter comprises between 3%-15% of the blend by weight, is formed by a method such as air-laying into a low density, high loft mat.

Abstract: The present invention relates to an apparatus and method and uses a thin, yet strong plastic film as the intermediate layer for the waterproofing material and the film has a plurality of perforations therein. The film is highly resistant to crack propagation, and acts as a barrier to crack propagation between adjacent asphalt layers, thus providing superior protection from the elements. The asphalt layers are interconnected with each other through the perforations in the polyester support layer. Because of the strength of the polyester film, only a very thin layer of polyester is necessary and this results in a substantial cost savings. As an alternative to coating, it is possible to extrude or laminate the asphalt onto the PET film. Also a layer of asphalt may be applied only to one side of said film and extruded through the perforations with heads on the columns so formed to attach the asphalt to the film.
