Best Thermal Performance

For homeowners in Sydney double glazing needs to perform for you. Achieving U-values as low as 1.4 is as good as it gets for a double glazed unit. This is achieved by using a warm edge spacer between the glass, and using recycled composite material as an option instead of steel for reinforcement of uPVC frames. It's 30% stronger, and doesn't corrode.

uPVC Features

uPVC is a leading material in the building market for double glazed windows. Not only is it easy to install, but it’s equally easy to maintain.

Unlike many timber products, which require rigorous maintenance and upkeep, uPVC only needs the occasional cleaning with soap and water.

That’s why we use it for most of our double glazed window and door products. Simply read about why we use uPVC in homes throughout Sydney and New South Wales.

Security Solutions

Almost all of our double glazed windows and doors are accredited against jemmying, mechanical manipulation, hard impacts and more. This helps to ensure that they are resistant to basic intrusion techniques.

However, we also offer double glazed windows and doors with another level of security accreditation. Most of our products can reach UK police security standards with a few simple upgrades.

Cool In Summer

Double glazing and triple glazing provide excellent insulation to help your air conditioning remain inside your home. If you’re interested in fire retardant products, read through the pages of our double glazed windows and doors to find out more.

Energy Efficient

Many of our uPVC profiles have a multi chamber design, which helps provide thermal ‘breaks’. Thermal breaks help to reduce heat conductivity, instead maintaining proper insulation for your home. That means keeping your home warm in the winter or cool in the summer wherever you are in New South Wales, or ACT.

What Our Clients Say

Michael Gross

Installed windows look great, attenuate external noise extremely well and offer excellent thermal insulation. Comparable product to windows in European houses.
Installation went smoothly. Lewis and team did a great job.

Dev Babu

We had about ten windows installed through them now. Very happy about the product – uPVC Windows – added so much ambience,  weather proofing and noise proofing to the rooms. Also five stars to the Lewis & Co – The Installers team – so friendly, no fuss and got the installation done in time.

David Zhou

I was one of the first customers of the Ecovue double glazed windows and doors. After 11 years of sun/weather, the doors and windows still look like new. Recently went back for wheels (roller) change, Lisa was very helpful patient and friendly. And the [wheels] are of top quality: the door is now moving smoothly like a dream!

Jen Coups

We have had a long journey with Ecovue windows which started late 2019. To say we have a lot of windows in our home (Hills District, Sydney) is an understatement. We have been working towards equipping our 1980’s build home to be more eco-friendly and energy efficient and double glazing is the way to go. The impact has been remarkable. We have reduced our energy consumption by 45%, that includes over the lockdown while we were home, running our ducted AC and with the introduction of a little one to the house. Our house remains a consistent 22 degrees in summer and winter.

Sarina Jennings

The decision to make over our house with new windows was at first a cosmetic one, until I spent some time overseas. After living a few years in England, I realised the benefits of double glazing. It was then that I was completely converted, and knew when I would return that this was something I would want to have in my home. I chose Ecovue because their product looked and felt the most authentic to the quality that is everyday in Europe and UK. I had gone through a few different companies to get an idea of measurements and quotes but in the end the ease of working with Ecovue was a valuable decision, because we had a number of windows, and decisions to make, which required patience and Warren was so helpful with that process. I have not looked back and I am enjoying both the functionality of the windows, and the ‘quiet’ and ‘consistent temperature’ throughout the home. They are so easy to open and shut and I absolutely love them. Thank you to Ecovue who also took care with professional installers and customer care. Best looking windows too!!
