Pvc Expansion Joint By Efforts Polymers (P) Ltd.

PVC Expansion Joint enable superior quality axial compression, axial extension and lateral deflection.

Also, the joints provide angular and torsion direction along with many other advantages.
EXPANSION JOINTS for roofs are designed to absorb the various movements when there are structural joints in place. Because of its shape, its central bulb can adapt to the various movements, while the two fins on the side constantly ensure excellent anchoring to bituminous or synthetic PVC felts. GDL bulb has two protective fins, while GDO bulb has as much as three fins, thereby ensuring greater protection. In some situations we recommend mechanically attaching the joints to the slab to ensure greater adhesion, especially with bituminous membranes. The joint can also be sealed directly on site with a normal hot air blower.

Provide excellent resilience to deterioration caused by the sun, ozone and other weather agents or chemicals normally found in the atmosphere. The elasticity of the material allows for excellent flexibility even at low temperatures, which ensures mechanical and physical properties are maintained over time. They are 100% compatible with SBS bituminous membranes and PVC prefabricated synthetic membranes. We recommend thoroughly cleaning the joint and the felt near the area where the profile will be glued. GDL and GDO joints can be used on roofs.
