Roll Out Rafter trays prevent loft insulation from being pushed up to the underside of the roofing underlay and will maintain a clear ventilation path into the roof void from the eaves to allow conforming the BS5250 (Control of Condensation).

• The rafter trays width must be selected based on the thickness of Insulation as well as the pitch of the roof to ensure full barrier is achieved. Trays can be overlapped if different widths are required.
