Why Melbourne Residents Replace Their Windows

The house is cold in winter and overheats in summer

Single-glazed windows can account for up to 35–40% of heat loss in winter and excessive heat gain in summer. This forces heating and cooling systems to work harder, increasing energy bills. Modern double-glazed windows create an insulating barrier that stabilises indoor temperatures year-round.

My windows are deteriorating or not working properly

Older aluminium windows corrode over time, while timber frames can rot, warp, or swell. Poor-quality windows often require ongoing maintenance and eventually fail to seal properly, leading to drafts and water ingress.

It’s too loud — I can hear everything from outside

Standard windows allow road traffic, construction, aircraft, and neighbourhood noise to enter the home. Acoustic double-glazed windows dramatically reduce outside noise, creating a quieter and more comfortable living environment.

The glass feels thin and unsafe

Many older homes still have thin 3 mm glass, which provides minimal protection against breakage. Modern replacement windows use thicker laminated or toughened glass for improved safety, durability, and security.

Condensation and dampness every morning

Condensation forms when warm indoor air meets cold glass surfaces. Persistent condensation can lead to mould growth, unhealthy indoor air, and damage to surrounding materials. Double-glazed windows reduce condensation by maintaining warmer internal glass temperatures.

Why Melbourne Homeowners Replace Windows

Older windows are one of the biggest sources of heat loss, drafts, and outside noise in Melbourne homes. Replacing them with modern double or triple glazed uPVC systems dramatically improves comfort, energy efficiency, and acoustic performance.

For decades, homeowners across Europe and North America have relied on high-performance uPVC windows to achieve warmer winters, cooler summers, and quieter living spaces. Now, Melbourne homeowners are making the same upgrade to future-proof their homes and increase property value.

Here are the most common reasons clients choose Windows Republic for window replacement.

Thermal efficiency

Glazing windows are an essential part of any home, as it helps to provide insulation and keep out the elements. The type of glazing used can have a profound effect on the home's energy efficiency, so it's essential to make sure you choose the right kind for your needs.

Double hung windows are one option when it comes to glazing windows. These types of windows consist of two sashes installed within a single frame, with both sashes able to be opened or closed independently.

Double hung windows provide excellent thermal efficiency thanks to their ability to trap warm air between them, reducing heat loss in winter and helping keep homes cool during summer months.

Condensation

Condensation on the glass is simply a sign of poor insulation qualities of your old window. A lot of heat escapes through thin glass in winter, causing moisture to accumulate on the glass.

Our classic product offering comes in double glazed configuration with Low-E glass and Argon gas as standard. The u-value for the classic offer starts at 1.6, which guarantees your windows to be condensation free. Please note that the argon gas is sealed within each IGU (insulated glass unit) and is non-toxic in case a glass gets broken.

Noise

Our windows consist of 70mm multiple chambered uPVC profile designed to keep the noise out. We offer various glass configurations ranging from double and triple glazed ones to laminated double glazed IGUs (insulated glass units).

Furthermore, proper installation is a big factor to the noise reduction qualities of your new windows. Your new frames get foamed all around followed by professional caulking, which eliminates any pathways for the noise to get through.

With our refit window replacements service you can say goodbye to outside noise.

Safety

All our window replacement timber products comply with Australian Standard (AS 2047) and are safe to use. We can offer either toughened or laminated glass in the areas which require extra safety.

The uPVC material does not discolour nor emit any toxic material when heated. Neither does it support combustion.

Quality

uPVC doesn't rust, nor rot, and lasts virtually a lifetime. Clever design coupled with top quality German hardware by SIEGENIA will guarantee your windows will last years to come.

Windows Republic offers 10 year guarantee as standard for your peace of mind.

Reviews

My window is a custom project with very thick glass. The main reason is reducing noise as much as possible. So the job done perfectly. The result is amazing. Thanks to Vladimir and Co. Highly recommend! Regards Dennis

Alex and his team recently did double glazing for us. It was a huge job with multiple large windows in a two-storey house. The windows are top quality with quality think glass. Windows Republic is great value for money and their quote was well below other companies. The noise and heat differences are noticeable. The final look and feel of the house are definitely a lot more premium. Thanks, Team!

Alex was great in understanding our needs and recommending the best fit for upgrading our windows to double glazing! We are very happy with the results and can highly recommend Windows Republic.

We're so thrilled with our new windows and doors, they've transformed our home! Great communication from Alex, timely work completed. Would definitely recommend to friends and family.
