Shear Expansion Joints End Termination On Roofs

Developed by emseal over 20 years ago shear pockets are a loop of santoprene thermoplastic rubber welded to replace the center member or cells of an expansion joint extrusion.

Shear expansion joints end termination on roofs.

When other conditions prevail the. In general the top surface of the curbs should be sloped away from the joint to shed condensation and moisture onto the roof. The eej cover is 60 mil thick reinforced epdm bellows widely used in roof to roof and roof to wall cant applications. Expansion joints are found in many building components.

Standard details show that the roof struc ture under roof expansion joints is intended to be discontinuous. A roof expansion joint emseal roofjoint is a patented dual seal double flanged extruded thermoplastic rubber system for sealing expansion joints in roofs. Expansion joint s zero profile is no trip hazard on the roof and is not affected by normal roof. Flintedge expansion joint is a multi part assembly design to facilitate the horizontal and lateral movement of curbs or roof sections.

Expansion joints in roofs require wood curbs around each roof area. In addition to roof applications roofjoint can be effectively used for softscape plazas as well as split slab and hardscaped decks when drainage or other construction may be impeded by the expansion joint protruding above the structural deck elevation. Nystrom s roof bellows system is an effective flexible joint closure for a wide variety of standard and special applications. Expansion joints in buildings no longer in print.

No metal fasteners therefore no possibility of thermal bridging or additional thermal heat losses. Shear pocket technology enhances movement of deck and roof expansion joints. Get moisture protection from the top down with roof covers from construction specialties. Browse roof expansion joint and roof expansion joint covers today.

Flat expansion joint is laid down at the roof membrane level over insulation leaving no void space for condensation to form. The flat expansion joint end termination accommodates movement in all three directions there is no warping curling or wrinkling at the joint termination. An expansion joint accommodates the expansion and contraction of building materials due to ambient temperature changes. The curbs should extend at least 8 or 10 if a cant is used above the adjacent roof.

The building research advisory board of the national academy of sci ences nas 1974 published federal con struction council technical report no. 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. The purpose of an expansion joint is to prevent stress damage cracking tearing splitting. In these cases an additional expansion joint seal would be needed at the wearing course.
