I'm building an insulated timber frame outbuilding. It's a fairly standard studword and PIR board design, the outside of which is clad in OSB sheet, then breather membrane, then vertical battens to provide a 25mm breather space, then cladding.
My question: Should the eaves/soffits be design so that the 25mm air gap behind the cladding has continuity in to the 50mm air gap in my roof, all the way up to my ridge vents?
Thanks
Gary
