We are pleased to announce the launch of a new extra wide roll panel vent in our roofing range, the G503.

Manthorpe roll-out rafter trays are designed to maintain a clear air path into the roof void from the eaves to prevent the build-up of damaging condensation. There are now three sizes of roll out rafter tray in the range with the introduction of a new 800mm wide roll designed to ensure a clear air path with lower roof pitches and increased levels of insulation.

The current G500 and G502 6m rafter rolls are specified by many major house builders due to their resistance to stretching and deformation which ensures that the ventilation air path into the roof, critical to avoiding roof-space condensation, is maintained and not blocked by insulation.

All three roll panel vents now carry the Manthorpe name embossed into the part. This enables easy identification – critical when the product is specified. The rolls are 6m in length and are available in black.

Continuous roll panel vents

The Manthorpe Continuous Roll Panel Vents are designed to maintain an open air gap between the underside of the roof membrane and the insulation down at the eaves, providing a flow of air to the roof space from the outside, thereby allowing the escape of built-up moisture that can cause condensation.

Made on a single roll that can cover a 6m run of the eaves, the panel can be rolled out over several rafters to create a ventilated gap beneath the felt running the span of the roof.

Suitable for 400mm, 450mm and 600mm raft centres, the panel's versatility makes it suitable for both new build and refurbishment situations where rafter centres are not consistent or unknown.

Wider versions of the panel, the G502 and G503 are suitable for use with extra thick insulation.
