Ridge Expansion Joint Roof

Emseal s manufacturing plants are open and operating at full capacity.

Ridge expansion joint roof.

Expansion joint covers and sealants for the built environment. 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. 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.

The position of the penetration should be well away from the low side of any sheet or step joint ridge capping or parapet flashing. Ridge covers should be designed to flex as the roof planes move together and away with expansion and contraction as shown in ridge details. Waterproof fire rated trafficable sound attenuating insulating air wind seismic and watertight building expansion joints and precompressed hybrid sealants. The curbs should extend at least 8 or 10 if a cant is used above the adjacent roof.

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 e280 is used both to create expansion joints on large roofs over 50m2 and create rolls on any ridge details and is compatible with c5 closures. 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.
