The White 70mm Round Soffit Air Vent is an essential component for homeowners and contractors looking to improve airflow within roof spaces, fascias, and eaves. Designed for both new builds and renovation projects, this vent effectively mitigates moisture build-up and heat accumulation to protect your roof structure, though it requires an existing 70mm aperture for installation. Its push-fit mechanism, integrated insect mesh, and durable finish make it a reliable choice for maintaining a healthy and well-ventilated attic environment.

This vent is designed to fit a standard 70mm diameter circular hole.
Yes, the product is specifically designed as a push-fit unit, which requires no screws or specialist tools for installation.
Yes, every vent features an integrated mesh grille to keep out insects and debris.
Yes, it is manufactured from weather-resistant plastic intended for outdoor exposure.
While the white finish is designed to be standard, you may use plastic-appropriate spray paint if a color change is required, though this is done at your own discretion.
The number of vents depends on the size of your roof space and local building ventilation standards; consult a professional if you are unsure about the required total airflow area.
Verify the diameter of the hole is exactly 70mm. If the hole is too large, the vent will not snap in securely.
Check the integrated mesh for buildup of leaves, dust, or insect nesting material and clear away obstructions.
Ensure the hole is not obstructed by structural timber or debris behind the soffit board and that it is perfectly round.
For a successful installation, ensure your soffit board has a cleanly cut 70mm circular opening. The vent features an 80mm outer diameter, which provides an overlapping flange to cover slight imperfections in the cut. To care for your vents, perform an annual visual inspection to ensure the mesh has not become clogged with debris or spiderwebs, which can restrict airflow. If cleaning is necessary, a soft brush or a light spray of water is typically sufficient. Avoid using harsh chemical cleaners that may discolor or weaken the plastic material over time.
