Termites

Termites, which have long been a natural part of the Australian environment, are no greater a threat now than they were at the time of European settlement. ABS figures suggest that the economic loss associated with termite damage is minimal, and that it does not rate as a significant cause of structural damage. Moreover, the likelihood of termites encroaching on a dwelling has nothing to do with the type of frame – timber, steel or brickwork - used in building the dwelling. By adhering to several simple design principles and basic maintenance, homebuilders can minimise any risk of termite damage. Modern termite management systems that deter termites or reveal their presence readily are highly effective. If detected, termites can now be eradicated without the need for dangerous chemicals. Modern timber framing systems can also be treated with non-harmful organic deterrents to provide additional protection if the termite risk is higher or you would like greater peace of mind.  Please refer to Blue Pine Framing for more information. 

The PPFA recommends that homeowners arrange annual inspections by a recognised pest controller. Such tests are relatively inexpensive and ensure that any termite encroachment is detected and acted on promptly.

Bushfire safety

The key issues in designing homes in areas of high bushfire risk centre on exterior fittings and proximity of the site to vegetation, and not structural materials. Construction standards for residential dwellings in bushfire zones make no reference to framing material. Research into fires indicate that houses in intense bushfire succumb when embers, often propelled by high winds, penetrate the exterior of a house, igniting furnishings and interior fittings. At this point there is the fire will almost inevitably destroy the house, regardless of the structural material used. Far from providing additional protection in the event of a fire, as is often claimed, steel frames are prone to softening and buckling in extreme heat. By contrast, timber frames follows a more predictable burning pattern and tend to support structural loads for longer in a fire. Anecdotal evidence from firefighters suggests they are less comfortable entering a steel-framed home in a fire than a timber-framed home, because of this lack of predictability.
