Abutment ventilation

Our specialist solutions have been designed to provide high-level ventilation at abutment joints, where the roof meets a wall or similar structure.

Our Glidevale Monovent and AbVent ranges have both been developed to be unobtrusive yet highly-effective at providing continuous ventilation into roof spaces. Both systems are fully compliant with BS 5250 Control of Condensation in Buildings, the primary means to comply with Building Regulations in the UK, and provide excellent driving rain and large insect resistance.
