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.

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.

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.
