“It’s important to check what materials were used in the construction of the house. Look out for exterior walls made of single-layered bricks supported by a wooden frame. Also, while wooden weatherboards were once common they have now been replaced by cheaper alternatives. These are fibre or cement sheeting, mostly known as Fibrolite, Hardiplank or monolithic cladding. (Hardiplank is known to have contributed to the leaky homes syndrome.) Check for roofs made of galvanised steel and tiles of bitumen, pebble or cement. These materials, while saving on cost of construction, often compromise the durability of these houses”. This is a bit of a muddle, brick veneer on a timber frame is very common form of NZ construction of single level homes, built to design specifications they should provide no problems at all, in fact many UK homes are brick veneer (double brick) on a timber frame.
Timber weather boards are still used, however the new form of fibre cement board under the brand of Linear are highly durable and not just a cheaper alternative. This form of weatherboard is a recent development. Fibrolite, Hardiplank and other monolithic cladding are used much less these days than in they were in the 90’s.作者: arnoking 时间: 2010-6-9 17:39:24
