Roof expansion joints

Aluminium or stainless-steel roof joints are designed to protect the joints and to ensure their watertightness even during large seismic movements. They can absorb large three-dimensional movements and they, thus, ensure the free movement of structures while providing a watertight roof. This prevents structures from colliding and ensures the durability of the structures and the safety of everyone. Our range also includes a special nitrile expansion joint to be connected directly to the general bituminous sheet waterproofing system. All our roof joints are compatible with our VEDAFEU fire protection systems.
