Technical purpose The G504 is a 1.25m wide Roll Panel Vent designed to maintain an air gap between the underside of the roofing membrane or sarking board and loft insulation at the eaves, to provide a continuous flow of air into the roof space.
The castellated profile is suitable for either 400mm, 450mm, or 600mm rafter centres, ideal for both new build and refurbishment where rafter centres are not consistent or unknown. The extra width of the panel allows for better coverage when lower pitch and deeper insulation details are encountered. |
