Common questions about uPVC double glazed windows
Yes — particularly in Melbourne and Victoria where temperatures range from below 5°C in winter to above 40°C in summer. uPVC double glazed windows reduce heat loss, block heat gain, and cut energy bills year-round. They also reduce noise significantly and add resale value.
uPVC stands for unplasticised polyvinyl chloride — a rigid, durable form of PVC widely used in window and door frames. Unlike timber or aluminium, uPVC frames do not rot, corrode, or require painting. They are thermally broken by design, fully recyclable, and the preferred frame material for double glazed windows in Australia.
For energy efficiency, uPVC significantly outperforms aluminium. Aluminium is highly conductive and transfers heat and cold easily, whereas uPVC is naturally thermally broken. uPVC also does not corrode in coastal environments and requires virtually no maintenance. While aluminium is cheaper upfront, uPVC delivers better long-term value.
Most residential installations take one to three days. Smaller projects involving a few windows can often be completed in a single day, while whole-home replacements typically take three to five days. Your home will never be left unsecured — all openings are fitted before the end of each working day.
