Circular Soffit Vent - Yellow

You need to drill a 70mm diameter hole.

While the vents are yellow, they can typically be painted to match your soffit boards using an appropriate exterior-grade plastic paint.

Yes, they can be used for new builds, though they are specifically marketed as an excellent retrofit solution.

This specific model is finished in yellow. Check with the manufacturer for alternative color availability if needed.

The number of vents depends on the volume of your roof space and local building regulations regarding ventilation requirements.

Ensure the hole was cut to exactly 70mm; if the hole is too large, the locking tabs will not catch properly.

Check for obstructions behind the soffit board or ensure the hole is free of plastic or wood burrs from the cutting process.
