Double glazing is one of those things that people either love or doubt. Some think it’s overpriced. Others assume it’s just for extreme climates. Then there are the myths, like aluminium frames being bad for insulation or double glazing not making much of a difference.
The truth is that double-glazed windows with aluminium frames are one of the best upgrades you can make to your home.
At Window Factory, we make high-quality double-glazed windows and aluminium joinery right here in NZ. In this article, we explain why double-glazed aluminium windows are worth it.
1. Superior Insulation and Energy Efficiency
The problem with inefficient single pane windows is that they let heat pour out in winter and creep in during summer. That’s because glass is a particularly efficient heat conductor, meaning it transfers heat way too easily.
Double glazing fixes this by adding an insulated glass unit (IGU). Instead of one thin pane of glass, you get two panes with a gap in between, filled with air or gas. That gap slows down heat transfer, keeping warm air inside when it’s cold and blocking heat when it’s hot.
But what about the window frame? Aluminium has a bad rep for being a poor insulator, but modern double-glazed windows with aluminium frames are built differently. They have thermal breaks. This is a special insulating layer inside the frame that stops heat from escaping. Pair that with quality thermal insulation from the glass, and you’ve got an energy-efficient setup that keeps your home comfortable all year long.
2. Noise Reduction for a Quieter Home
Ever had to turn the TV up because of street noise? Or been woken up by the sound of early morning traffic? That could be because you have single pane windows. And they do next to nothing to block sound.
Double glazing adds an extra barrier between you and the outside world. Sound has to travel through not one, but two panes of glass, plus the insulating gap in between. This reduces how much noise gets into your home. It can make a huge difference if you live near a busy road, a school, or just have noisy neighbours.
For even better results, different glass thicknesses can be used in the two panes, which helps block a wider range of frequencies. If peace and quiet matter to you, upgrading to double-glazed windows with aluminium frames is one of the easiest ways to get it.
3. Strength, Security, and Durability
If you’ve ever had a home with timber windows, you probably know the hassle. For instance, swelling in winter, shrinking in summer, peeling paint, and the constant risk of rot. Aluminium windows don’t have those problems. Aluminium doesn’t warp, crack, or rust, and it handles NZ’s wild weather without breaking a sweat.
Then there’s security. Double glazing makes your home harder to break into. Two panes of glass are way tougher to smash than one, and combined with strong aluminium frames, you’ve got a setup that makes life pretty difficult for intruders.
Unlike some materials, aluminium doesn’t need regular maintenance. No sanding, no repainting, no worrying about termites. Just wipe it down when it gets dirty, and you’re good to go. If you want double glazing that will last for decades with minimal effort, aluminium frames are the way to go.
4. Condensation and Moisture Control
Waking up to wet, foggy windows in winter is really annoying. It’s also a sign of poor insulation. Condensation happens when warm air inside meets the cold surface of a window. With single pane windows, there’s nothing stopping that heat transfer. So, moisture builds up fast.
Double glazing helps by keeping the inner pane warmer. The air gap between the two panes slows heat loss, which means your windows stay clearer and drier. Less condensation also means less mould, better indoor air quality, and fewer damp issues in your home.
Tired of wiping down your windows every morning or dealing with mould creeping up the walls? Double-glazed aluminium windows can make a big difference.
5. Home resale value
If you ever sell your house, buyers will look for things like good insulation, low maintenance, and modern features. Double-glazed windows with aluminium frames tick all those boxes. They help keep power bills down, block out street noise, and make a home feel more solid and comfortable. That’s a big plus when you’re trying to get a good price.
And unlike timber windows, aluminium won’t need sanding, painting, or replacing anytime soon. It’s one less thing for buyers to worry about, which can make your home more appealing. Even if you’re not planning to sell anytime soon, it’s a smart long-term upgrade.
