Hi- I’m hoping I can ask for some advice from some knowledgeable people here! - especially as google is giving me such alternating advice!!!
I have recently had a 20x10ft summerhouse/workshop built for my sewing business- a way to get everything out the house and away from the kids!!!
I’d like this to be useable all year round and so am looking to insulate with 50mm Celotex/Kingspan/similar and then osb board over the top.
I’ve been reading lots of info on having breather material such as Tyvek fitted between the shed wall and the insulation. The problem is that the joists are already in place as it came in ready made panels so we would have to attach the membrane to the side and around the joists- so the membrane would be in contact with the insulation.
I really want to make sure that we do this properly as I’m planning on using this as my workshop for the foreseeable future and don’t want to have rotting wood or other issues down the line.
I’m planning on having a small fan heater just to warm the space up when needed- and never unattended.
Advise would be really appreciated as to fitting of a breather membrane and whether it is necessary. And if so whether we can fit it around the joists (not sure that’s the correct term for them!)
Many thanks
