The Vents UK gravity shutter is an essential component for homeowners and contractors looking to improve external ventilation, specifically designed for those needing a robust 150mm ducting solution. It excels at preventing backdrafts and pest entry through its automatic shutter mechanism, though it requires precise surface mounting to ensure the gravity blades move freely without obstruction.

This model is designed as a gravity shutter and does not typically include an integrated insect mesh, as that can interfere with the blade movement.
It is designed primarily for extraction. Using it for intake may cause the shutters to remain closed unless there is significant pressure.
It is made from high-quality, durable, UV-stabilized plastic suitable for long-term outdoor use.
Yes, you can use an appropriate plastic-bonding spray paint, but ensure it does not get into the hinge mechanism of the shutters.
The 150mm refers to the spigot size, which is the diameter of the ducting that inserts into the wall.
Check if the unit is mounted on an uneven surface causing the frame to flex, or remove debris obstructing the hinge pins.
Ensure the shutter is installed perfectly level, or apply a very small amount of weather-stripping foam to the internal frame stop.
To install, ensure your existing ducting is flush with the exterior wall. Use the 185mm x 185mm footprint to mark and drill pilot holes for the screws. It is recommended to use a bead of exterior-grade silicone sealant around the perimeter of the flange to prevent water ingress behind the unit. Maintain the unit by checking it annually for debris, such as leaves or spider webs, that might impede the movement of the shutter blades. Clean with a damp cloth if necessary; do not use harsh chemical solvents that could degrade the plastic finish.
