2-ply

Updated: May 1, 2025

The roof has a single matchboarding inside, but on the outside is a matchboarding, then a layer of 2-ply 'ruberoid, then a layer of quilted seaweed, then a second matchboarding, and finally a cover of 3-ply 'ruberoid. The first floor is laid, but over this there will be a quilting, a felt layer, a second boarding, and finally linoleum; as the plenteous volcanic sand can be piled well up on every side it is impossible to imagine that draughts can penetrate into the hut from beneath, and it is equally impossible to imagine great loss of heat by contact or radiation in that direction.
