The Permavent 6 m Universal Ventilated Dry Ridge System is designed to provide a mechanically fixed, weather-resistant ridge detail for pitched tiled roofs. The system forms a continuous weathertight seal along the ridge line and is compatible with most common ridge tile profiles.
The system provides continuous high-level roofspace ventilation equivalent to 5,000 mm2/m at the ridge, in accordance with the requirements of BS 5250:2021, supporting moisture management within the roof void. It is installed without the use of mortar, reducing reliance on wet trades and allowing consistent installation in varying weather conditions.
The dry ridge system is intended to deliver long-term performance through mechanically fixed components that accommodate roof movement while maintaining ridge stability and wind uplift resistance and weather resistance.
