Product Description 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.
