We've been speaking to several BC and energy assessment people around a large heated log cabin I've mentioned previously is going in our garden.
I'm trying to get a grip on what the big issues will be and in broad strokes how we might address them and want to get someone on board who is sympathetic to the design and works with it rather than just following the same approach they always use on more traditional designs.
The solid 70mm wooden walls come up quite often, in regard to part L (insulation etc) and also part C (moisture). One guy told me that basically, any new wall MUST have a cavity regardless of other considerations. He seemed to be saying we'd have to put a damp liner on the walls, then an air gap, then an insulated layer inside a stud wall, which all seemed a bit overkill.
Do the regs put explicit rules on HOW you do things, or only what the end result is? In this case, is a cavity required explicitly, or is it just a typical way to meet certain requirements?
