A type of vent typically installed in the soffit (the area beneath the roof's overhang) to promote proper airflow in the attic. This ventilation helps to prevent moisture buildup, reduce the risk of mould, and improve overall roof health by allowing cooler air to enter and warmer, potentially humid air to escape.

• The round shape allows for a streamlined appearance and can sometimes be less obtrusive than square or rectangular vents
• For openings of 70mm diameter
• Easy push fit - no fixings required
• Increase roof ventilation to prevent condensation and associated problems
