- Onduline cladding
- low-emissivity double glazing
- passive solar heating
Low-maintenance Onduline cladding is used on the outside. This type of exterior cladding is made from waste paper that has been coloured with natural pigment resin, then soaked with bitumen. This material does not rot, rust or become brittle and offers a highly effective thermal insulation.
Double glazing with low-emissivity glass helps insulate the house. Low-E glass is coated to let short wavelength solar energy in from the outside, while reflecting longer wavelength heat from inside back into the house. This type of double-glazing conserves as much energy as triple glazing, without the added weight. It also helps reduce condensation considerably.
Exposed concrete flooring provides passive solar heating.
New Zealand plantation-grown macrocarpa timber was used extensively. Macrocarpa wood has the benefit of not requiring toxic treatment. Salvaged swamp totara was used for the upper floor.
