I'm planning to insulate my loft conversion with kingspan; 35mm between the roof rafters and 100mm under, going across the rafters.
How do I then attach plasterboards to them? For the screws to go through the plasterboard, kingspan and into the rafters 25mm I'll need 137mm screws. I can only find 100mm plasterboard screws. Is there another way of doing this or do I need to keep looking for longer screws?
