We insulate the floor, walls and ceiling with insulation made from recycled plastic bottles. It is a bit more expensive than rock wool but it feels better to know that we are not putting harmful stuff into the build.

Rockwool (typical insulation) is made by spinning molten rock with minerals and steel particles to create a light fleece insulation roll. Unsurprisingly the fibres are very itchy on the skin and unpleasant to breathe.

The insulation we use is very effective – helping keep the structure warm. Most people tell us their cabin is better insulated than their house.
