Frequently Asked Questions
Are aluminium windows and doors better than timber?
Aluminium windows and doors are valued for their durability, low maintenance and structural strength. Unlike timber, aluminium does not swell, warp or require regular repainting, making it well suited to coastal and high-exposure environments. Timber can offer a warmer aesthetic, but aluminium is often preferred for modern designs, larger spans and long-term durability with minimal upkeep.
How long do aluminium windows and doors last?
Well-manufactured and properly installed aluminium windows and doors can last decades. Powder-coated finishes resist corrosion and fading, while quality hardware ensures smooth operation over time. Lifespan depends on exposure conditions, installation quality and maintenance, but aluminium is widely regarded as a long-term solution for residential construction in Australia.
Do aluminium windows improve energy efficiency?
Aluminium windows can contribute to improved energy efficiency when paired with appropriate glazing and proper installation. Glass type, frame design and sealing all influence thermal performance. Well-sealed units reduce drafts and heat transfer, helping maintain more stable internal temperatures and reducing reliance on heating and cooling systems.
