Roof Expansion Joint Material

Expansion joints in roofs require wood curbs around each roof area.

Roof expansion joint material.

Check out the interactive illustration of some applications and products. Joint sizes range from 1 to 2. 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. Emseal expansion joints and sealants seal the gaps throughout the building envelope.

Get support at every phase of your project. This aluminum roof cover is comprised of extruded aluminum components injection molded turn bar duroflex gaskets and a polyethylene vapor barrier. In general the top surface of the curbs should be sloped away from the joint to shed condensation and moisture onto the roof. It is ideal for applications where exterior seals are used in walls and watertight transitions are critical.

A roof expansion joint emseal roofjoint is a patented dual seal double flanged extruded thermoplastic rubber system for sealing expansion joints in roofs. Nystrom s roof bellows system is an effective flexible joint closure for a wide variety of standard and special applications. The curbs should extend at least 8 or 10 if a cant is used above the adjacent roof. From the ground to the roof there is an emseal product available to handle your needs.

The waterproofing element of most other roof expansion joints is a looped membrane. Waterproof fire rated trafficable sound attenuating insulating air wind seismic and watertight building expansion joints and precompressed hybrid sealants. Expansion joint covers and sealants for the built environment.

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. The eej cover is 60 mil thick reinforced epdm bellows widely used in roof to roof and roof to wall cant applications. Compression seals 15 expansion joint systems 45 fire barrier systems 4 material. 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.
