Termites and borers are a real cost of timber outdoors in Australia. Aluminium simply gives them nothing to eat.
A genuine timber problem
Across much of Australia, termites and borers are an ongoing threat to timber outdoors - especially fence posts, rails and any wood near ground contact. Treatment and repair are recurring costs.
Nothing to attack
Aluminium gives termites, borers and rot nothing to feed on. A woodgrain aluminium fence or facade keeps the timber look while removing the pest and decay risk entirely.
Where it matters most
The benefit is sharpest on fences and ground-level elements, where timber fails first. Aluminium posts and boards stand where timber palings rot and lean.
