Expand o gard expansion joints are flexible waterproof closures for vertical building walls designed to accommodate movement between building components caused by thermal settlement wind flex and seismic forces. Joint sizes range from 1 to 2. Expansion joints in roofs require wood curbs around each roof area.

Aluminum 2 epdm 3 steel 2 finish. The curbs should extend at least 8 or 10 if a cant is used above the adjacent roof. Expansion joint systems 5 material. Our exterior joint systems provide superior aesthetics by hiding joint seams to maintain that crisp look.

Factory fabricated intersections are designed for maximum flexibility and are produced using special fabrication techniques to ensure watertight clean seam lines. Continuous flexible rubber membrane thermal and seismic movement curb mount installation roof 1 to 24 systems. 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.
