Double glazed windows in Sydney start from around $750 per window supplied and installed by Newage, roughly 30 to 40 percent more than the same window single glazed. Two panes of glass with a sealed air or argon gap cut heat transfer by about half compared with single glazing (Uw around 3.0 to 4.0 against 6.0 or more), and with a laminated acoustic pane they take up to 35 dB off street, rail and flight noise. We make them in Smeaton Grange in awning, sliding, double hung and fixed styles, measure free, and install with our own team across Sydney.
Built in our Smeaton Grange workshop and installed by our own team across Sydney and surrounding regions, from Camden and Campbelltown to Parramatta, the Hills and the Sutherland Shire.
One upgrade that improves comfort, noise, energy use and security.
The insulating gap cuts heat transfer, so you spend less on heating and cooling all year.
Two panes of glass block more outside noise for a quieter, more peaceful home.
The insulated design helps reduce condensation, which cuts the risk of mould and mildew.
An extra pane of glass makes windows harder to break, improving your home security.
Every figure below is for a standard aluminium frame from our KlassicView range with 4mm/12mm/4mm clear double glazed units unless stated. Ask for the WERS certificate for the exact unit you are quoted.
| Glass option | Uw (lower is better) | SHGC (solar heat) | Noise reduction | Best for |
|---|---|---|---|---|
| Single glazed 4mm clear | 6.0 to 6.5 | 0.75 | about 25 dB | Sheds, garages, like for like budget swaps |
| Double glazed clear | 3.5 to 4.0 | 0.65 | about 30 dB | Most Sydney homes, bedrooms and living areas |
| Double glazed Low-E | 2.8 to 3.4 | 0.45 to 0.55 | about 30 dB | West facing rooms, BASIX targets on new builds |
| Double glazed with 6.38mm laminated acoustic pane | 3.2 to 3.8 | 0.60 | up to 35 dB | Homes near the M5, M7, rail lines and flight paths |
| Double glazed Low-E toughened | 2.8 to 3.4 | 0.45 to 0.55 | about 30 dB | Doors, low sills and wet areas under AS 1288 |
Uw is the whole window heat loss rating used by BASIX and NatHERS; SHGC is the share of the sun’s heat that gets through. Noise figures are weighted reductions (Rw) for the glass, so a well sealed frame matters as much as the glass. Secondary glazing, a second pane fitted inside your existing window, gives a similar noise result but leaves the old frame and its draughts in place, which is why we recommend replacement units for anything older than about 20 years.

See the difference double glazing makes to comfort, noise and energy use in a home.
The right choice depends on the room, the noise outside and your budget. This is the short version we give customers at the measure.
Two panes with a sealed gap between them. Add Low E or acoustic glass for more. This is what we make and fit.
A third pane adds weight, thicker frames and cost. In Sydney, double glazing with Low E glass gives most homes the comfort they want.
A second pane fitted inside the old window. It can cost less, but the old frame stays and it does not seal like a new double glazed unit.
Aluminium frames stay slim and strong across large openings. See how the two frame types compare.

“The double-glazed windows are not only beautifully designed but have already made a significant difference in my home’s energy efficiency. I noticed an immediate reduction in outside noise, making my home feel much quieter and more comfortable.”
“I’ve noticed a huge improvement in energy efficiency, especially with maintaining indoor temperature, and the noise reduction has been amazing… The installation was completed smoothly, with excellent attention to detail and no mess left behind.”
“The installation team was professional, punctual, and extremely careful with both the fit and finish. They walked me through the process, answered all my questions, and left everything clean and tidy.”

Double glazing costs more than single glazing, but it pays off over time through lower energy bills and better comfort. Price depends on the window style, size, glass and number of windows, but as a guide double glazed windows usually start from around $750 supplied and fitted. We give free, no obligation quotes for homes across Smeaton Grange, Camden, Narellan and Campbelltown, with a fixed price before any work starts.
No. Newage makes and installs complete new aluminium double glazed windows, so we replace the whole window, frame and glass, in the existing opening. We do not reglaze timber or old aluminium frames. A new frame also seals much better than an old one, which is where a large part of the comfort and noise benefit comes from.
Replacing a window in the same opening with one of a similar size is generally treated as exempt development in NSW, so most homes do not need council approval. Making the opening bigger, changing a load bearing wall or working on a heritage listed home can need approval and an engineer. We check this at the free measure, and you can read the rules on the NSW Planning Portal.
