The DryVent Ridge System provides a continuous weathertight air path from the roof void to
the outside within a mechanically fixed ridge, complying with the requirements of the Building Regulations. The systems neat appearance and proven security makes it an ideal choice for the discerning specifier. The system can also be easily converted when no high level ventilation is required at the ridge.
Roll-Fix is manufactured using a highly vapourpermeable polypropylene membrane, a mesh fabric with a high ventilation ratio yet completely weatherproof. The central, flat 'spine’ of the roll sits on the ridge batten, while the two corrugated-profile side flaps are designed to drape down over the top row of tiles on either side as the roll is opened out along the ridge line. The lower corrugated portion of each side flap, including the visible lower edge, is finished with a durable, U/V-stable coloured aluminium coating.
