Roof Expansion Joint Material

Nystrom s roof bellows system is an effective flexible joint closure for a wide variety of standard and special applications.

Roof expansion joint material.

Joint sizes range from 1 to 2. Expansion joints in roofs require wood curbs around each roof area. In general the top surface of the curbs should be sloped away from the joint to shed condensation and moisture onto the roof. Expansion joint covers and sealants for the built environment.

The eej cover is 60 mil thick reinforced epdm bellows widely used in roof to roof and roof to wall cant applications. This aluminum roof cover is comprised of extruded aluminum components injection molded turn bar duroflex gaskets and a polyethylene vapor barrier. Waterproof fire rated trafficable sound attenuating insulating air wind seismic and watertight building expansion joints and precompressed hybrid sealants. Compression seals 15 expansion joint systems 45 fire barrier systems 4 material.

Each expand o flash cover is a combination of a flexible rubber membrane supported by a closed cell foam to form flexible bellows with two metal flanges adhesively and mechanically combined to the bellows by a patented bifurcation process. Each expand o flash cover is a combination of a flexible rubber membrane supported by a closed cell foam to form flexible bellows with two metal flanges adhesively and mechanically combined to the bellows by a patented bifurcation process. Expand o flash expansion joint covers are flexible weather proof exterior covers for expansion joint openings and are an effective flexible closure for a wide variety of standard and special applications. It is ideal for applications where exterior seals are used in walls and watertight transitions are critical.

The curbs should extend at least 8 or 10 if a cant is used above the adjacent roof. A roof expansion joint emseal roofjoint is a patented dual seal double flanged extruded thermoplastic rubber system for sealing expansion joints in roofs. Get support at every phase of your project. Expand o flash expansion joint covers are flexible weather proof exterior covers for expansion joint openings and are an effective flexible closure for a wide variety of standard and special applications.

Gaf everguard everguard extreme expansion joints are made of 60 mil thick reinforced tpo membrane and come in five standard sizes and two convenient styles to accommodate both roof to roof and roof to wall applications. Watertightness is achieved through positive integration with the roofing membrane and a purpose designed system for transitioning between the joint in the roof and joints in walls. Check out the interactive illustration of some applications and products. From the ground to the roof there is an emseal product available to handle your needs.
