PM FIRST- AND GRAT-ROLLE PREMIUM DUO (PREMIUM DUO RIDGE AND ARRIS ROLLS)
Ridge and arris roll
PM PREMIUM DUO 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.
PM PREMIUM DUO RIDGE AND ARRIS ROLL combines different materials to create a compact system that fulfils requirements for ventilation and safety even in the rain or snow.
Ventilation through the ridge and arris are ensured thanks to the specialised structure of the material. Despite the open surface, PM PREMIUM DUO RIDGE AND ARRIS ROLL remains sealed, offering excellent protection against moisture penetration.
An additional seam ensures the aluminium and mesh materials are bonded together at all times. The roll is highly flexible and lays independently on the top row of roofing tiles. The flanged edge protects against injuries. The bonding is done with the integrated high-quality butyl strips on both sides.
