A fibrous papermaking felt for carrying a paper web through a paper making process includes a resilient layer of glass fibers and a fabric backing layer.

Papermaking felts from irregular fibers

This invention produces three-dimensional shapes such as window lineals by first lining a foam die with a continuously moving reinforcing veil. Once the veil is in the foam die, a foam is blown into the die. The foam expands in the die forcing the veil against the die wall. The veil is selected so that the foam never fully penetrates the veil, but adheres to it. The material exiting the foam die is now properly shaped to enter the curing die. Resin is then injected onto the foam core where it penetrates the veil, is cured in the heated curing die and exits as a finished product of a plastic skin adhered to a foam core with a veil sandwiched therebetween.

Method for making shaped members using a foam froth

A roof includes a roof deck and a plurality of roofing shingles where the roofing shingles have the appearance of a wooden shake shingle and comprise organic, resinous material in, preferably a plastic material, an amount within the range of from about 16 to about 24 percent by weight, and a filler material in an amount within the range of from about 76 to about 84 percent by weight. The roof provides a Class A fire barrier when tested according to ASTM test E108-93 for flame spread, burning brand and intermittent flame.
