Floplast Black 5m Soffit Board Unvented Single Round Edge

The FloPlast Black 5m Unvented Single Round Edge Soffit Board is designed to finish the underside of a suitable roof overhang. Its black uPVC surface gives the eaves a clean, consistent appearance and reduces the need for routine painting compared with traditional bare timber soffits.

The title identifies a 5m board length, while the live width options are 100, 150, 175, 200, 225, 250, 304 and 404mm. The old description also referred to white colour options, but this particular listing is for Black. It is unvented, which is an important distinction from a vented soffit board.

Choosing the right materials

Measure the soffit depth at several points along the roofline and allow for support and any trims. Choose the correct board width and work out the number of 5m lengths needed, including joints and cuts. Check the roof's required ventilation strategy before buying an unvented board: ventilation may need to be provided elsewhere within the approved roof detail.

Installation and maintenance advice

Install with suitable support, fixings and finishing trims following FloPlast's current spacing and movement requirements. Allow for uPVC thermal expansion and do not block required roof ventilation paths. When renewing an old soffit, examine the rafters and roofline timber and repair any decay or water ingress before covering it.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
