20110072736 | DRAINAGE MEMBERS FOR FLAT ROOFS AND METHODS OF MAKING SAME - Processes of making slightly sloped roofing members/products ( | 03-31-2011 |
20110008629 | STRUCTURAL LAMINATES MADE WITH NOVEL FACING SHEETS - A laminated panel comprises at least one facer comprising a coating applied to a facer sheet to provide a coated facer surface, and a thermosetting plastic foam firmly adhered to the coated facer surface. In an example, non-limiting embodiment, the facer sheet comprises a nonwoven glass mat; the coating comprises a coating mixture comprising a mineral pigment and a dried latex; and the thermosetting plastic foam is comprised of an insulation material selected from the group consisting of polyurethane modified polyisocyanurate foam, polyurethane foam, and phenolic-formaldehyde foam. In an example variation, the nonwoven glass mat has the coating applied to two opposing flat surfaces thereof. | 01-13-2011 |
20100087114 | METHOD AND COMPOSITION FOR COATING MAT AND ARTICLES PRODUCED THEREWITH - A coated glass mat comprises a glass mat substrate having non-woven glass fibers and a coating which essentially uniformly penetrates the glass mat substrate to desired fractional thickness of the coated glass mat. The coating imparts a tensile strength to the coated glass mat which on average is at least 1.33 times greater than the tensile strength of the glass mat substrate without the coating. In example embodiments, penetration of the coating into the glass mat substrate preferably extends to a depth of from twenty five percent of a thickness of the coated glass mat to seventy five percent of the thickness of the coated glass mat. Moreover, a non-coated thickness of the coated glass mat is sufficiently thick for bonding purposes with, e.g., a gypsum slurry or other core materials such as thermoplastic or thermosetting plastics. The coating has a porosity in a range of from 1.3 CFM to 5.0 CFM, e.g., the coating comprises a coating blend which provides the coated glass mat with a porosity sufficient to allow water vapor to escape from a gypsum slurry when heated. The coating is preferably a coating blend comprised of water, latex binder, inorganic pigment, and inorganic binder. | 04-08-2010 |

20090038257 | Hip and ridge shingle, method and apparatus for making, and method of using same - A web of roofing material ( | 02-12-2009 |
20090023350 | Building construction felt paper with biocide/anti-microbial treatment - A nonwoven web has a weight sufficient for construction industry use and comprises at least forty percent (40%) recycled waste paper. At least one surface of the web bears a biocide, e.g., has a biocide applied thereto. Preferably the weight of the web is greater than fifteen pounds per thousand square feet (15-lbs/MSF). Preferably the biocide is zinc pyrithione. The web preferably bears at least 50-grams of biocide per thousand square feet per side of said web. One example use of the web is as builders felt, with other uses including as a facer for a laminate board and for asphalt-impregnated webs. The biocide-bearing nonwoven web is specifically directed to use in building construction. One example use of the web is as builders felt, with other uses including as a facer for a laminate board and for asphalt-impregnated webs. Because building construction products must be tough, but priced as low as possible, this web is made largely from recycled waste paper (as opposed to virgin cellulose fiber, as a cost-reducing measure), and optionally clarifier sludge. | 01-22-2009 |
