450mm uPVC Vented Soffit Board x 5m

Q: Do I need vented soffit?

Use vented soffit on a cold roof, where the roof space needs air at the eaves to stop condensation. If ventilation is already handled another way, such as over-fascia vents, flat soffit is fine.

Q: How much ventilation does it give?

The built-in slots give a continuous 10mm air gap along the length of the board.

Q: How quickly can I get it?

White is usually with you in a few working days. Delivery is £9.99, or free on orders over £150, and you can collect from a local depot instead.

A 450mm vented soffit board closes off the underside of your roof overhang and lets air into the roof space through built-in slots, giving a continuous 10mm air gap. That stops condensation forming on the rafters. It comes in 5m lengths, needs no painting, and wipes clean. These are Eurocell boards. This width comes in white only.

What a 450mm vented soffit board is used for

A 450mm vented soffit board suits deep overhangs. Use vented soffit on a cold roof, where the loft is insulated at ceiling level and the roof space needs airflow at the eaves.

How to measure for 450mm vented soffit

Measure from the back of the fascia to the wall, at a few points along the run, and take the widest reading. If you're between sizes, take the wider board.
