Australiaís climate can be a nightmare for houses. In some areas temperatures can rise and fall as much as 30 degrees in a single day, causing expansion, contraction, movement and cracking of joints.
Thatís why Paal Kit Homes builds flexibility into its frames, so areas such as internal cornices or mouldings donít Ďpopí and leave ugly gaps and cracks.
Like major engineering structures such as the Sydney Harbour Bridge, Paalís homes are bolted rather than welded, allowing the framework to give and take with the stress of the climate.
Roof trusses have bolt holes that are minutely larger than the bolt diameters to allow expansion and contraction of the girder members without affecting the length or width of the roof.
Typically in Paalís seven or eight metre roof truss, the climate will cause no overall expansion or deflection at all. This is unheard of in a welded metal truss or timber truss.
Another advantage of bolt-together roof sections is that one person can handle them and you donít need a lifting device such as a crane to get them up into position.
