A Smarter Choice for Double-Glazed Windows Sydney-Wide

Double glazing in Sydney goes beyond aesthetic appeal. Our uPVC windows offer protection and comfort with:

Thermal Insulation & Energy Savings

Stay cool in summer and warm in winter with our double-glazed windows. Our windows are argon-filled and have warm-edge spacers, so there’s no need to rely heavily on air conditioning and heating systems. This design helps reduce energy consumption by up to 70%, and has a reflection rate 300% greater than regular windows.

Healthier Homes – Reduced Condensation & Mould Prevention

Integra’s high-performance uPVC double-glazed windows significantly reduce condensation by maintaining warmer interior glass surfaces and minimising temperature differences. By reducing moisture build-up around windows, they help prevent the conditions that encourage mould growth, creating a healthier, drier and more comfortable living environment for your family.

Windows Double Glazed with uPVC: High-Performance Solutions

Air Infiltration

Air infiltration occurs when outside air enters a home through gaps around windows and doors, increasing heat loss in winter and heat gain in summer.

Integra’s uPVC double-glazed windows use compression seals around the opening sashes to minimise air leakage and unwanted draughts. This reduces the demand on heating and cooling systems, helping maintain more stable indoor temperatures and improve energy efficiency.

Thermal Efficiency

Heat transfers through windows via the glass, frames and gaps around the openings. Standard aluminium frames conduct heat readily, while uPVC is naturally insulating.

Integra’s window double glazing combines uPVC frames with two panes of glass separated by an argon-filled cavity. Argon gas reduces heat transfer between the panes, while warm-edge spacers help minimise heat loss around the glass perimeter.

Together, these features reduce heat transfer through the window, helping lower heating and cooling requirements.

Noise Reduction

Double glazing is your solution against noise pollution. This combo can slash perceived noise by up to 80%, thanks to its multi-layered design and superior sealing.

Enjoy better sleep, less stress and a more peaceful living space.

7 Star Energy

7-Star Energy Rating – Exceptional Efficiency Without Compromising Design

Achieving a 7-star energy rating shouldn’t mean compromising on the architectural vision of your home.

While conventional glazing solutions may require smaller openings to meet energy efficiency standards, Integra’s high-performance uPVC double-glazed windows offer superior thermal insulation, helping you maintain generous glass openings without sacrificing energy efficiency.

Our structurally reinforced double-glazed uPVC windows combine advanced glazing technology with exceptional thermal performance, giving architects, builders and homeowners greater design flexibility while supporting Australia’s 7-star energy rating requirements.

Because energy efficiency should enhance great design, not limit it.

Stars on Google reviews

We have engaged Integra Windows to provide a quote for changing about 100 windows in our small block of 24 in Woolwich, in a bushfire prone zone and marine environment. Integra from day 1 has been very helpful and professional through a long 12 months process of preparing the proposal and information gathering. Thank you Integra Windows

Emir R

My house needed urgent repairs. After doing a lot of research I decided on using European style uPVC windows and doors. Integra Windows were willing and able to help me at short notice and provided a fantastic set of replacement windows and doors. I am really pleased with the way they worked and finished the project. Thanks for a great job.

Andrew

I could not speak more highly about both the product and service I received from Integra Windows. The service I received from the initial consultation to the installation was absolutely amazing. Integra accommodated my time frame for my renovation of the home and provided me with new uPVC windows and doors with a commendable turn around time. Thanks again the wonderful team!

Antonia F

From sales to installation they were fantastic. There were some hickups from both sides but everything was quickly addressed and solved without fuss. We did a total rebuild and every trade that visited our site complimented the windows and asked us for your name. Thanks again for a great job and we have no hesitation in recommending Integra.

Chris and Kate

I had old leaky timber windows in my house. In the middle of winter, my house was cold place! Got Integra Windows to replace all my windows and haven't been happier. Their installers carried out the work expertly and efficiently.

Cannot recommend these guys enough. The pleasure from start to finish and the house is now much warmer.

Emil

I have been building top-end homes and small projects for 20 years... and have not found a product like this anywhere in Victoria. Flew up to Sydney to confirm my order and pick the hardware. When the windows and installers arrived, everything was spot on. The install was quick and efficient. Windows worked great from the get-go. Next project I'm only using Integra. Couldn't be happier.

Are uPVC windows better than aluminium?

arrow

uPVC windows offer significant advantages over standard aluminium, particularly in thermal insulation, energy efficiency and comfort.

Does uPVC change colour over time?

arrow

Quality uPVC is engineered to withstand Australia's harsh climate, including intense UV exposure, extreme temperatures and coastal conditions. Unlike traditional materials, uPVC profiles contain advanced UV stabilisers that help prevent fading, yellowing and discolouration, ensuring your windows and doors retain their original appearance for years to come. Durable, weather-resistant and virtually maintenance-free, uPVC is an excellent long-term investment for Australian homes.
