Abstract: A promoted membrane suitable for use in single-ply roofing applications is disclosed. The membrane comprises EPDM rubber and 0.1 to 10 wt. % of an adhesion promoter. The promoter comprises a polyester resin having a hydroxyl number within the range of 28 to 250 mg KOH/g, a content of terephthalate recurring units within the range of 40 to 65 wt. % based on the amount of polyester resin, and a glass-transition temperature within the range of 40° C. to 80° C. Roofing systems comprising the promoted EPDM membranes are also disclosed. Compared with an unpromoted membrane, the promoted membranes provide a substantial and unexpected boost in peel strength such that the roofing systems resist weather-induced failure of the bond between the roofing membrane and the roof substrate. The invention helps roofers minimize or limit the aggravation and cost of warranty claims from customers whose buildings and contents may otherwise be damaged or destroyed by exposure to wind and/or rain.

Abstract: During installation of a single-ply roofing membrane, the surface of the membrane can be protected from dirt, scratches and scrapes by a protective sheet which also provides other beneficial attributes that aid an installer. A roof laminate includes a roof membrane and a protective sheet is removably affixed thereto. The sheet includes at least a first layer directly secured to a second layer. The first layer provides at least one of UV protection, anti-slip, and anti-glare to the roof laminate and so aids the installer in at least one of those respects. The second layer is removably affixed to the roof membrane.

Abstract: A roof structure comprises a roof membrane and a roof substrate. A first surface of the roof membrane is adhered to the roof substrate by a two component adhesive, the adhesive being capable of adhering the first surface of the roof membrane to the roof substrate 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.

Abstract: A PVC-based cover strip designed to bond to non-PVC materials as well as PVC materials includes a PVC layer coated with a barrier effective to prevent migration of plasticizers from the PVC layer. The barrier layer, in turn, is coated with a primer and subsequently a pressure-sensitive adhesive. The barrier layer is generally a polar polymer, such as acrylonitrile rubber which resists migration of phthalate plasticizers. The pressure-sensitive adhesive layer is a pressure-sensitive adhesive suitable for use in roofing applications.

Abstract: A method of making an enhanced membrane suitable for use in single-ply roofing applications is disclosed. The method comprises mixing a masterbatch comprising an EPDM rubber and combining the masterbatch with a curing package to form a final batch. An adhesion promoter is incorporated in either the masterbatch or the final batch. The method further includes forming a sheet from the final batch and vulcanizing the sheet.

Abstract: A roofing board, such as a polyiso insulation board, includes first and second surfaces, where the first surface is lighter in color than the second surface. This allows the roofing installer to choose which of the surfaces to expose to the atmosphere, the lighter surface being cooler than the darker surface. The lighter surface may have a solar reflectance greater than the darker surface. A roofing membrane is then adhered or otherwise attached to the exposed surface.

Abstract: A fire-resistant polymeric membrane includes a polymer layer such as PVC, TPO, or EPDM affixed to a carbon fiber composite. The carbon fiber composite includes one or two layers of non-woven carbon fibers and at least one of an inert fiber mat or a metal foil layer, wherein the metal foil layer has a melting temperature of at least about 660° C. The present invention also provides an underlayment, wherein the underlayment is formed from one or more fibrous carbon layers affixed to at least one of an inert fiber mat or a metal foil having a melting temperature greater than 660° C.
