Waterproof fire rated trafficable sound attenuating insulating air wind seismic and watertight building expansion joints and precompressed hybrid sealants.

Ridge expansion joint roof.

Ridge covers should be designed to flex as the roof planes move together and away with expansion and contraction as shown in ridge details. Expansion joints in roofs require wood curbs around each roof area. In general the top surface of the curbs should be sloped away from the joint to shed condensation and moisture onto the roof. A roof expansion joint emseal roofjoint is a patented dual seal double flanged extruded thermoplastic rubber system for sealing expansion joints in roofs.

An adequate gap in the deck should be cut if necessary the trim should then be nailed to each end of the decking at 300mm centres. The position of the penetration should be well away from the low side of any sheet or step joint ridge capping or parapet flashing. 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. Penetrating the roof should be taken into consideration if it is subject to vibration heat expansion etc special attention is drawn to the need for an adequate drainage path at the front and sides of the penetrations.

Emseal s manufacturing plants are open and operating at full capacity. The force to disengage the ridge connection to the end dams and the end dam fixity to the panel should be examined to be sure the system can accommodate the forces encountered with panel movement in both directions.
