Hi
after some advise if I may, I’m looking to purchase a house with a very large loft room which has no insulation so the heat loss is unreal and trying to work out project costs.
I have 150mm rafters which have plasterboard on the underside and as I’ve said no insulation....trying to work out my options and was thinking of removing the old plasterboard then applying super quilt stapled onto the rafters (so a large air gap is left to vent the roof void) 25mm batons fitted down the rafters then 50mm insulated plasterboard fixed to the batons.
Is this ok to do or go I need a bigger air gap between the super quilt and insulated plasterboard?
Thanks in advance.
