Perpendicular Roof Expansion Joint

Perpendicular and parallel to the joint in the horizontal roof plane and perpendicular to the roof in the vertical plane.

Perpendicular roof expansion joint.

The waterproofing element of most other roof expansion joints is a looped membrane. This is better than putting horizontal colorseal in a curb and terminating the roof membrane on the curb because that approach lacks a positive roof membrane integration. In general the top surface of the curbs should be sloped away from the joint to shed condensation and moisture onto the roof. Standing seam roofs are more flexible in the direction perpendicular to the ribs as compared to the direction of the ribs.

The curbs should extend at least 8 or 10 if a cant is used above the adjacent roof. Browse roof expansion joint and roof expansion joint covers today. The roof manufacturer s recommendations should be consulted and followed relative to the distances between expansion joints. Expansion joints in roofs require wood curbs around each roof area.

A roof expansion joint emseal roofjoint is a patented dual seal double flanged extruded thermoplastic rubber system for sealing expansion joints in roofs. 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. Because like with our fp systems for plaza decks the roofjoint flanges ensure a static positive integration of the expansion joint to the roof membrane. 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.

Thus expansion joints can be spaced at greater distances than those perpendicu lar to the ribs. They are designed to accommodate the free movement of building elements without damage to the roofing system.
