<p>The roofing system uses a waterproof membrane incorporating bonded insulation as a bottom layer. This has been pre-formed to fit over the roof trusses and is help in place by pressed steel fixing brackets which have been designed to lock securely on to the two rolled steel roof battens. These battens can be rolled as a one piece section. The outer cladding is laid onto these battens in a unique arrangement and held in place with special locking clips. A variety of different clips have been designed to accommodate all cladding currently available.</p> |
