[papercreters] Re: Just posted some new photos of new walls

In our damp climate (about 56" rain per annum), a vapour barrier on the exterior of an insualting wall is a Bad Idea. It causes saturation by condensation inside the wall, leading to mould, and with papercrete there would be rot too.

A vapour barrier on the interior side is a good thing, keeps the wall drier. The way water vapour works with house walls is often misunderstood.
