Corner and edge joint fittings are used to facilitate and speed up the laying of the membranes near the corners and edges of the roof. Their use provides excellent waterproofing and a good aesthetic result. They are available in various materials, sizes and formats to best solve the problems encountered on site. Tapered joints are used to connect waterproofing near cables of various installations, such as antennas, air conditioners, photovoltaic panels, etc. The elastic material with which they are produced ensures long-term watertightness. They have excellent resistance to deterioration caused by the sun, ozone andother atmospheric or chemical agents normally present. The elasticity of the raw material with which they are produced allows for excellent flexibility even at low temperatures, enabling the mechanical and physical characteristics to remain unchanged for a long time. They are fully compatible with prefabricated TPO synthetic membranes. Thorough cleaning of the fitting and the synthetic membrane is recommended near the area where they are connected to the joint fittings.
