Roof Expansion Joint Material

The curbs should extend at least 8 or 10 if a cant is used above the adjacent roof.

Roof expansion joint 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. Check out the interactive illustration of some applications and products. Joint sizes range from 1 to 2. 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.

Get support at every phase of your project. 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. Waterproof fire rated trafficable sound attenuating insulating air wind seismic and watertight building expansion joints and precompressed hybrid sealants. 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.

Nystrom s roof bellows system is an effective flexible joint closure for a wide variety of standard and special applications. From the ground to the roof there is an emseal product available to handle your needs. The eej cover is 60 mil thick reinforced epdm bellows widely used in roof to roof and roof to wall cant applications. It is ideal for applications where exterior seals are used in walls and watertight transitions are critical.

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.
