The model Coppo is a roofing sheet suitable for residential and rural applications on buildings, shelters, garages, bungalows and gazebo. This model has a ridge that allows connection between two opposite roof slopes. Installation of the Coppo roofing sheet is made using dedicated fixing accessories; screws for wooden or metal purlins, o’ring caps (which cover the sheet profile and provided with o’ring seal grant watertight on the screw holes) and screw covers (which protect the screw head from atmospheric agents). Sheets are lightweight, easy to transport and install, resistant to fire, shocks and chemical/atmospheric agents and able to give high thermal and acoustic insulation.
