Abstract: An injection molded shower stall assembly or bathtub assembly particularly for use in a recreational vehicle includes an injection molded tub or shower base, which includes an integrally formed drainpipe which is externally threaded and adapted to easily and permanently be connected to plumbing for the recreational vehicle. Injection molded walls are formed to surround either the shower stall or tub. The injection molded walls have lower edges that interfit with edges of the tub or shower stall in a way which prevents water from flowing behind the preformed walls and holds the lower edges of the preformed walls in position, eliminating the need for any type of penetrating fastener along the base of the walls. The walls are formed in multiple sections that fit one on top of the other, with interfitting lower and upper edges, again to reduce the need for penetrating fasteners and to hold the sections in position.

Abstract: A method of roofing an occupancy structure comprising providing a roofing membrane that comprises at least one thermoplastic membrane layer, bonding the roofing membrane to the roof of an occupancy structure, where the occupancy structure includes a roof member that is at least partially constructed of a plastic material and extends above the roofing membrane when the roofing membrane is applied to the occupancy structure. A substantially solid hot melt thermoplastic sealant is heated to enable the substantially solid hot melt thermoplastic sealant to flow and a layer of the substantially solid hot melt thermoplastic sealant is applied to an exterior surface of the thermoplastic membrane layer and a plastic portion of the roof member to seal the joint between the roofing membrane and the roof member.

Abstract: A custom shutter includes a central body portion and first and second end caps. The central body portion includes two stiles and a central portion all of which are formed integrally as one piece. The top and bottom end caps include first and second legs and a central connecting body portion. The legs are designed to be inserted within the hollow interior of the stiles with the top edges of the stiles resting against the stepped portions of said end cap and wherein an inner surface of said end cap covers any exposed edge of the central portion of the shutter body.

Abstract: A roof system for a mobile occupancy structure having a roof substrate and a roof member mounted to the mobile occupancy structure may include a roof membrane having at least one thermoplastic vulcanizate (TPV) membrane layer affixed to the roof substrate. The roof system may also include a sealant disposed about or adjacent the roof member with the sealant being adhered to the TPV membrane layer. The TPV membrane layer includes a TPV polymer bonding additive and the sealant includes a sealant polymer bonding additive with the TPV polymer bonding additive and sealant polymer bonding additive interacting to promote adhesion of the sealant with the TPV membrane layer. The sealant may be a substantially solid sealant having at least approximately 90% solids by weight prior to being applied about the roof member.

Abstract: A wall system and method of manufacturing a wall for a manufactured building is disclosed including gluing a wallboard to a frame made from perimeter plates and stud members. After the wallboard is glued to the frame, an elongate rigid rail member is removably attached to the board to hold the board and frame together during glue set up and curing. The rail member is removed after the glue has cured.

Abstract: Apparatus for producing methane and other products by processing a slurry of biodegradable waste materials including two tanks containing waste material which are connected to allow fluid flow communication between slurry in each tank, each tank being airtight with respect to the ambient, one of said tanks containing a cathode and the other tank containing an anode to aid in the growth of methane producing bacteria, the tanks provided with movable hoods for collecting gas.
