Looking for any advice on insulating our summerhouse. It’s 10x6ft 21mm loglap and I’ve got leftover Eko roll loft insulation that I’m planning on packing between the battens then panelling over with plywood or Osb. After seeing a lot of talk about damp membranes I’m confused about how to go about it?
I think it should go external wall>insulation>membrane>panelling however as it’s just a single layer external wall I’ve seen conflicting advice about putting a membrane up between the external wall and insulation?
Also in regards the roof, am I correct in thinking if im using the wool I should leave a 50mm gap between it and the ceiling board?
I know this is never going to be perfect just looking to make it a room that’s usable year round. All advice welcome
