Double Glazed Double Hung Windows for Melbourne Homes

If your home has old timber sash windows that stick, rattle, and let cold air pour through the gaps, uPVC double hung windows Melbourne homeowners are upgrading to give you the same classic look without any of the problems.

Double hung windows, also known as vertical sliders, work the way traditional sash windows always have: two panels that slide vertically past each other. Slide the bottom sash up for ventilation, slide the top sash down to let warm air escape, or open both for natural cross flow. The difference is everything behind the glass. Nu-Eco’s uPVC frames replace the old timber, the weights, and the fraying pulleys with precision-engineered multi-chambered profiles, triple seals for superior draught proofing, and 28mm double glazed units that stop heat and noise at the glass.

Because double hung windows slide vertically, they need no exterior clearance. That makes them the right choice where outward-opening styles like casement windows would swing into a walkway, verandah, or boundary wall. They’re also the natural fit for heritage and period homes where the sash window look is part of the streetscape. Pair them with sculptured ovolo windows across the rest of the home for a consistent period aesthetic.

Every double hung window is made to order as part of Nu-Eco’s double glazed windows and doors in Melbourne range, available in a full selection of colours and woodgrain finishes including golden oak and rosewood. Book a free measure and quote to see how the upgrade transforms your home.

Slider Double Hung Windows - Common Questions

Got questions about replacing old sash windows, pricing, or how double hung compares to other styles? Start here.

Pricing depends on the size, quantity, glass specification, and optional extras like Georgian bars, reveals, or upgraded glass. As a guide, Nu-Eco’s double glazed windows start from approximately $1,600 to $1,800 installed for a standard opening. A free on-site measure and quote gives you the exact cost for your home.

Double hung windows slide vertically and need no exterior clearance, making them ideal beside walkways, verandahs, or boundary walls. Casement windows are side-hinged and swing outward, offering maximum airflow but requiring clearance outside the opening. Double hung windows also have a traditional sash appearance that suits heritage and period homes.

You can. Nu-Eco’s double hung windows feature an innovative tilt-in mechanism that lets both sashes tilt inward, giving you access to the outside glass from inside the room. No ladders or exterior access needed.

uPVC double hung windows replicate the look of traditional timber sash windows but eliminate the maintenance. No painting, no sanding, no swollen frames in winter, no fraying cords or jamming weights. The uPVC profiles are steel-reinforced for structural rigidity and will not rot, warp, or corrode. For a detailed comparison, see our guide on timber frames vs uPVC.

All Nu-Eco windows are independently certified to Australian standards by a NATA-accredited facility. They are AWA and WERS certified, rated N4 for non-cyclonic regions and C2 for cyclonic. Water penetration testing recorded zero ingress at 600pa, four times the standard requirement of 150pa.

Every double hung window includes an anti-jemmy bar and steel-reinforced profiles to resist forced entry. The sashes lock securely when closed, and all glass is internally glazed so it cannot be removed from outside. A ventilation lock position allows the window to be partially opened while remaining secured.
