Double Glazed Casement Windows Built for Melbourne Homes

If your current casement windows rattle when the wind picks up, fog with condensation on winter mornings, or sit in aluminium frames that transfer cold straight into the room, uPVC casement windows Melbourne homeowners are switching to will change how your home feels overnight.

Casement windows are hinged at the side and swing fully outward, opening the entire sash area to catch breezes and channel fresh air through the room. That makes them the strongest ventilation option in Nu-Eco’s range, ideal for living rooms, bedrooms, and home offices where you want real airflow, not just a gap at the top. With no horizontal mid-rail breaking up the glass, you also get clean, unobstructed views and maximum natural light.

For rooms where the opening is wider than it is tall, or where you need ventilation that stays open in the rain, uPVC awning windows are the better choice. Many Melbourne homes use both: casements in living areas and bedrooms, awnings in kitchens and bathrooms. Nu-Eco builds both to the same standard, so mixing styles across your home means consistent quality and performance in every room.

Our casement windows come with tri-stay ezi-clean hinges, letting you reach the outside of the glass from inside your home. They’re available in a clean-cut chamfered finish or a heritage profile to suit period homes. Every window is made to order as part of Nu-Eco’s uPVC windows and doors in Melbourne range. Book a free measure and quote to see what the upgrade looks like for your home.

Why Choose Casement Windows for Your Home?

Old aluminium casement windows are one of the weakest points in a Melbourne home’s insulation. The frames conduct heat and cold directly through the wall, the single glazing does almost nothing to block noise, and the hardware wears out over time leaving gaps that let draughts in. Timber casements have their own problems: rotting sills, peeling paint, and swollen frames that jam shut in humid weather.

Replacing them with uPVC double glazed casement windows eliminates all of that, with frames that never need painting and sealed glass units that stop condensation before it starts. Nu-Eco’s casements are built as soundproof windows that cut traffic noise dramatically, available in a full range of colours and timber-look finishes, and backed by the benefits of double glazed windows that pay back on energy bills year after year.

  • Maximum Ventilation

  • Unobstructed Views

  • Easy Clean From Inside

  • Enhanced Security

  • Low Maintenance uPVC

We had our windows installed today by two skilled professionals - Mitch and Simon. They arrived on time and did a very good job. Left our rooms clean and tidy. We are very happy with the look and a big improvement to our home. Thank you both.

We had a fantastic experience with Nu Eco Windows. Adam was friendly, professional and helpful when he visited to measure and provide a quote. The installers also did an excellent job fitting our new attic window, completing the work with care and attention to detail. The finished window looks fantastic and has made a wonderful addition to our home. We could not be happier with the result and would gladly recommend Nu Eco Windows to anyone looking for quality workmanship and great service.

We got all our windows replaced with double glazed windows from nu-eco. We're happy with the quality of the windows and options they had available. One thing that is the most outstanding is their customer care. They were super friendly and explained everything well. Anytime something was a tiny bit strange, we called and someone came the next day to fix it or have a look. All their employees are extremely friendly, considerate and helpful.

I have had three projects completed by Nu-Echo. They are a trustworthy, efficient, and cost-effective service, and they are the best in the market. They always arrive and perform repairs promptly.

Had Adam come up for a measure and quote. From the first phone call he was incredibly friendly and helpful. Answered all my numerous questions without hassle. He arrived on time for our appointment, did a comprehensive measure and spoke about the window design. He also had samples with him to showcase their product. No hard sell and had my quote later that day. I can't fault the customer service provided by Adam. Great assest to the company.

Everyone involved in this order was a pleasure to deal with. A salesman that didn't give me the hard sell and was happy to give me multiple options to mull over with no pressure. Office staff who addressed all my questions promptly. The installation crew who were very polite, always checked with me before making anything final, left the place clean and tidy. This is my second time using Nu-Eco and while I have no plans to ever move house again if it should ever happen they will be my first choice for new doors & windows.

We have had our bedroom windows installed by Nu Eco windows in 2023 we only had 2 done to see how they went. We waited 6 months for install which was explained to us from the get go as they are made overseas. With my wife been European this was great as we were getting a product the same as in Europe. On the day of install it took a good 5 hours. Once it was done the installer told us they would be ordering a new window as the one they installed had a very tine 1cm scratch at the bottom which you would never see unless looking for it. This made us proud we went with NuEco windows. They swapped our window out a month later. We continued to use them for the 2nd bedroom and kitchen windows all up 4 windows 2024 The team were amazing. They spoke to us through problems they came across as the house is 20 years old and rectified it without fuss or extra charge. Needless to say its now 2026 and we are about to call them to come quote our last 2 windows. The team really know what they are doing we had a number of reps from other businesses come out and try the hard sale and push and didn't really know their product well NuEco was the complete opposite. Adam and Andy and great to deal with.

Casement Windows - Common Questions

Everything you need to know about pricing, performance, and how casement windows compare to other styles.

Pricing depends on the size, quantity, glass specification, and any optional extras like reveals or upgraded glass. As a guide, a standard uPVC double glazed window starts in the range of $1,600 to $1,800 installed. Nu-Eco provides a free on-site measure and quote so you know the exact cost before committing to anything.

Casement windows are hinged at the side and swing outward like a door, opening the full sash area for maximum airflow. Awning windows are hinged at the top and open from the bottom, which lets them stay open during rain. Casements suit taller openings in living rooms and bedrooms. Awnings suit wider openings in kitchens and bathrooms. Many Melbourne homes use both.

Yes. Nu-Eco’s double glazed casement windows achieve a certified U-value of 1.5 W/m²K with standard glass, more than three times better than a typical single-glazed aluminium window. The multi-chambered uPVC frame does not conduct heat the way aluminium does, keeping your home warmer in winter and cooler in summer.

You can. Nu-Eco casement windows include tri-stay ezi-clean hinges that allow the sash to swing inward far enough for you to reach the outside glass from inside the room. This is particularly useful for windows on upper floors or in hard-to-access positions.

UPVC frames insulate significantly better than aluminium because they do not conduct heat. Nu-Eco’s casement windows also feature fully welded corners with an air infiltration rate of just 0.1 L/sec, compared to the Australian standard allowance of 5.0 L/sec. They will not corrode, rust, or need repainting.

Every casement window comes with a European multi-point locking system, shoot bolts as standard, and UK Secure by Design Police accreditation. A night vent locking position lets you leave the window slightly open for airflow while remaining locked. All glass is internally glazed, so it cannot be removed from the outside.
