Abstract: A roofing system including a roof deck and a membrane assembly secured to the roof deck. The roof deck may be a flammable roof deck. The membrane assembly includes a roofing membrane and a fire resistant sheet, the fire resistant sheet, or a portion thereof, secured to the membrane. The fire resistant sheet includes a fabric substrate and a binder.

Abstract: A chemically coated roofing membrane assembly includes a membrane and a chemical coating on at least a portion of one surface of the membrane. In one or more embodiments, the chemical coating may be provided along the top surface of the membrane adjacent to a longitudinal edge of the membrane, and along the bottom surface of the membrane adjacent to a second longitudinal edge of the membrane. The chemical coating is cured, and may be formed from acrylic or urethane chemical compositions. The chemically coated roofing membrane eliminates the need for in-field priming of the membrane.

Abstract: A multi-layered membrane comprising a first layer that is substantially white in color; and a second layer including ground thermoset rubber.

Abstract: A method of transporting insulation panels to a location, the method comprising providing a plurality of insulation panels; placing a predetermined number of said insulation panels into stacks, said stacks including a top surface, lateral sides and a bottom surface; covering said stack with a heat shrinkable material, wherein said heat shrinkable material covers said top surface and said lateral sides, at least a portion of said material extending below the intersection between said bottom surface and said lateral sides; heating said heat shrinkable material, thereby shrinking said heat shrinkable material substantially flush against said lateral sides; loading a plurality of stacks on a vehicle; and moving said vehicle with said plurality of stocks to the location.

Abstract: A method for manufacturing polyurethane and polyisocyanurate foams comprising the steps of charging at least one blowing agent and a polyol component to an in-line continuous mixer, wherein the at least one blowing agent and the polyol component are continuously charged in separate streams advanced at predetermined flow rates chosen to bring about a desired ratio of blowing agent to polyol component within the in-line continuous mixer.

Abstract: A composite recovery board (10, 20, 30) comprises a foam core (11) having lower (12) and upper (13) surfaces, wherein the foam core is selected from the group consisting of polyisocyanurate and polyurethane materials and mixtures thereof; and a filler within said foam core selected from the group consisting of rubber-tire vents, EPDM scrap material, plastic chips, polyurethane scrap, polyisocyanurate scrap, scrap rubber from recycled tires, wood chips, fiberglass strands and mixtures thereof. A method of re-roofing a roof comprising applying composite boards (10, 20, 30) of the present invention to a roof deck and applying a weather protective layer over the composite boards. A continuous method of making composite recovery boards (10) of the present invention comprises is also provided.

Abstract: A method and apparatus for fabricating roofing crickets includes the steps of generating the dimensions of roofing cricket components, which when assembled, form the roofing cricket. Knowing the dimensions of each cricket component, a cutting assembly which utilizes a rotatable cutting saw and is controllable in an X-Y plane is controlled to cut each cricket component from a tapered insulation board. The cricket components can then be assembled into the roofing cricket.

Abstract: An apparatus for forming venting channels in a continuously-formed foam product includes a plurality of channel-forming plates which are removably attachable to the upper endless-type conveyor of a rigid foam laminating apparatus. The channel-forming plates provide a molding surface to form transverse channels in the foam product during the foaming operation. The channel-forming plates are easily removed for repair and/or replacement and include a centering bar which accurately positions each plate on the endless conveyor. The channel-forming plates are configured to form generally U-shaped channels in the upper surface of the continuously formed foam product to provide venting channels when the foam product is cut and used in roof insulation. The product and venting channels therein are sized to provide a continuous channel when a plurality of the foam panels are used as well as to facilitate attachment to standard trusses or joists.
