4. Roofs

At first glance, this house appears to have walls made of paper. In fact the paper is used, during construction, for keeping the insulation material, Pink Batts in place between the jib board inner walls and the outer decorative brick walls.



The more popular roofing material used in NZ is colour bond steel (90%) formatted to look like ceramic tiles. Leaks are minimised by using less number of  joints by fabricating whole sheets using a simple cold form machine on site. Ceramic tiles, due to its greater weight and more chance of leaks, are less popular in NZ (about 10 %).

On building sites it is usual to see only one or two men working on a house at any one time. On the same building project in Malaysia, we will see at least 5 to 10 people, because of the cheaper cost of labour there.
