Hi
I've done a search already but not quite found the answer to my specific question.
Basically i'm building a new wooden garage\workshop from scratch. The walls are going to be made from 2"x4" and clad in waney edge\featheredge boards. I'd like to insulate it properly as i'll be spending quite a bit of time in there so my question is would it be wise to wrap the whole stud wall frame in some sort of breathable membrane first before before cladding the outside?
then with regards to insultating it after that i was going to fill the wall cavities with 600mm wide glass cavity slabs then ply board the inner walls.
Does that sound like it will work or is there some other vapour barrier aspect i need to take into account?
Also there will be a gap (at present due to the current design) to the outside where the roof trusses meet the top of the wall frames. Does this gap need closing/insulating or is this needed for air to circulate?
Any help very much appreciated as is any recommended brands of products or exact specs of materials i need to ask for at my local builders merchants
cheers
Matt
