Abstract:
PROBLEM TO BE SOLVED: To provide a membrane roof which can keep a white roofing membrane clean during installation of a new membrane roof.SOLUTION: A roofing laminate 10 includes a roofing membrane 12, preferably a white roofing membrane, which is covered with a protective sheet 14. The protective sheet is tinted so that it has a coloration distinguishable from the roofing laminate. The roofing laminate is applied to a roof surface and the release liner protects the outer surface of the roofing membrane from scrapes and dirt during installation. Once the roof is installed the protective sheets are removed from all of the roofing membrane sheets, exposing a clean surface.
Abstract:
A roof structure (1 0) comprises a roof membrane (16) and a roof substrate (1 2). A first surface of the roof membrane (16) is adhered to the roof substrate (12) by a two component adhesive, the adhesive being capable of adhering the first surface of the roof membrane (16) to the roof substrate (12) without the use of a high VOC solvent. The two component adhesive includes a Michael donor and a Michael acceptor, and the Michael donor and the Michael acceptor react to form an adhesive film (24).
Abstract:
A roofing board, such as a polyiso insulation board (10), includes first and second surfaces (1 1, 12), where the first surface (1 1 ) is lighter in color than the second surface (12). This allows the roofing installer to choose which of the surfaces (1 1, 12) to expose to the atmosphere, the lighter surface (1 1 ) being cooler than the darker surface (12). The lighter surface (1 1 ) may have a solar reflectance greater than the darker surface (12). A roofing membrane (14) is then adhered or otherwise attached to the exposed surface.
Abstract:
A wall structure (10) formed from multipurpose laminated foam boards (18). The foam boards (18) include a thin dense outboard layer (40) and a thick less dense inboard layer (42). Further, the boards (18) include an integral self-sealing water barrier layer (48) on the outer surface of the board (18), which allows the board (18) to be nailed or screwed directly to the wall studs (12).
Abstract:
A roof system (10) designed to retain water during storms and release it slowly over a period of time includes a polymeric water impervious membrane (15) covered with a drainage board (16) in turn covered with a water retention mat (18). The water retention mat (18) and drainage board (16) are held in position by ballast (20), preferably gravel. The mat (18) is designed to retain at least about 25% of a one-inch per hour rainfall and release it gradually over 2 to 3 hours, thereby reducing rain runoff during storms and reducing the load on a storm sewer system.
Abstract:
A power transmission belt (10) is provided with a peroxide-cured, polybutadiene-based elastomeric composition. The elastomeric composition includes 100 parts of a rubber derived from 50 to 100 parts by weight of polybutadiene rubber; 0 to 50 parts by weight of at least one other rubber; about 1 to about 20 parts by weight per 100 parts by weight of total rubber (phr) of a type I coagent; about 1 to about 20 phr of a type II coagent; and about 0.1 to about 10 phr of a peroxide curing agent.
