Energy Efficient Windows Melbourne. Cut Heating & Cooling Bills by Up to 40%

Nu-Eco energy efficient windows come standard with Low-E coated glass, 28mm argon-filled IGUs with a 20mm spacer, and fully welded uPVC frames that act as a natural thermal break. Our standard specification achieves U-values of 1.4–1.5 W/m²K, with options to push as low as 0.8 W/m²K through upgraded glass configurations.

Every frame is manufactured by the UK’s largest uPVC supplier using the highest-grade profiles and the latest production equipment. The sealed double glazed units also reduce condensation on interior glass surfaces, protecting your walls and surrounds from moisture damage. Available in Awning, Casement, Tilt & Turn and Double Hung styles with a wide range of colour options, you get premium energy performance without compromising on the look or feel of your home.

Nu-Eco has over 25 years of experience supplying and installing uPVC double glazed windows across Melbourne. Our products are manufactured by the UK’s largest uPVC supplier and independently tested to Australian Standard AS2047 by a NATA-accredited facility. We service homes, apartments and commercial properties right across metro and regional Victoria.

Based in Dandenong South, our team specialises in helping Melbourne homeowners reduce their energy consumption through high-performance glazing solutions. Every product in our range is AWA and WERS certified, and we work with you to select the right glass specification for your home’s orientation, climate zone and efficiency goals. With over 60 staff and thousands of completed projects across Melbourne, Nu-Eco is the name homeowners trust for genuine energy savings.

Upgrading to uPVC double glazed windows makes an immediate difference to your Melbourne home’s energy performance. Our 28mm argon-filled insulated glass units with Low-E coating create a thermal barrier that keeps warmth in during winter and heat out during summer — reducing your heating and cooling bills by up to 40%

The fully welded uPVC frames play an equally important role. Unlike aluminium, which conducts heat rapidly, uPVC is a natural insulator with no thermal bridging. Combined with sealed, airtight construction and no gaps from mechanical joins, Nu-Eco windows achieve certified U-values as low as 1.4 W/m²K — outperforming many triple glazed alternatives in WERS testing. That means less reliance on heaters and air conditioners, lower energy bills year-round, and a smaller carbon footprint for your household.

Every Nu-Eco energy efficient window is custom manufactured to your exact measurements and professionally installed by our experienced team. Precision fitting is critical for thermal performance — even small gaps around a frame can undermine the insulation value of the best double glazed unit. Our fully welded construction and tight tolerances ensure airtight results every time.

We handle everything from single room upgrades to whole-home replacements across Melbourne metro and regional Victoria. Whether you’re swapping out draughty old aluminium frames or fitting out a new build to exceed minimum energy ratings, our team manages the job from first measure to final sign-off. Every installation comes with a free measure and quote, and is backed by our product warranty — no subcontractors, no shortcuts.
