External Walls Original section double brick, extension brick veneer.
Insulation Second storey extension heavily insulated (walls, ceiling & floor) using polyethalene boarding.
Floor Floors in the extension are 19mm Yellow tongued flooring topped with 19mm spotted gum solid boards. This gives a total of 38mm both ground and 1st levels, plus carpet squares throughout. This results in excellent insulative qualities.

Heating & Cooling For heating, an Archer gas heater, which burns 90% of the gas, is used. It only requiring a downward flue for the water and fume by-products. No cooling required due to the NE breezes in summer. Inside temperature considerably less than outside. Water
