Roof expansion joint material.
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.
In general the top surface of the curbs should be sloped away from the joint to shed condensation and moisture onto the roof.
Nystrom s roof bellows system is an effective flexible joint closure for a wide variety of standard and special applications.
The waterproofing element of most other roof expansion joints is a looped membrane.
A roof expansion joint emseal roofjoint is a patented dual seal double flanged extruded thermoplastic rubber system for sealing expansion joints in roofs.
Emseal expansion joints and sealants seal the gaps throughout the building envelope.
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.
Expansion joint covers and sealants for the built environment.
From the ground to the roof there is an emseal product available to handle your needs.
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.
This aluminum roof cover is comprised of extruded aluminum components injection molded turn bar duroflex gaskets and a polyethylene vapor barrier.
The curbs should extend at least 8 or 10 if a cant is used above the adjacent roof.

Joint sizes range from 1 to 2.
Expansion joints in roofs require wood curbs around each roof area.
It is ideal for applications where exterior seals are used in walls and watertight transitions are critical.
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.
The eej cover is 60 mil thick reinforced epdm bellows widely used in roof to roof and roof to wall cant applications.
