PM FIRST- AND GRAT-ROLLE STANDARD (STANDARD RIDGE AND ARRIS ROLLS)
Ridge and arris roll
PM STANDARD RIDGE AND ARRIS ROLL is a simple, fast solution for safe roof ventilation. It fulfils the regulations of the German Roofing Association, which require safe, permanent roofing ventilation to prevent damage caused by moisture.
Despite the open surface, PM STANDARD RIDGE AND ARRIS ROLL remains sealed, offering excellent protection against moisture penetration. PM STANDARD RIDGE AND ARRIS ROLL stands out with its flexibility and ease of finishing and can be attached to the centre of the ridge batten with a stapler or with nails.
The roll is highly flexible and lays independently on the top row of roofing tiles. An additional seam ensures the aluminium and mesh materials are bonded together at all times. It offers excellent breathability in the centre section and is highly UV resistant and waterproof thanks to environmentally resistant materials.
