Quality double-glazed windows are a game-changer for home comfort, energy efficiency, and security. Originating in Victorian-era Scotland, double glazing (now sometimes triple or even quadruple glazing) involves multiple glass panes separated by a sealed layer of air or gas.
Most people know that double glazing helps reduce energy costs, enhance security, and minimise noise. What sets double-glazed windows apart is how they are made and the materials used.
How are double-glazed windows made?
Each double window unit consists of three key layers:
- An external glass panel
- An insulting air gap
- And an internal glass pane
These layers are sealed within a durable, airtight frame to deliver superior thermal and acoustic performance.
External Pane
This is the first barrier against environmental elements like heat, cold, rain, and noise. At Action Glass & Aluminium, we use a variety of high-quality glass types, including toughened and laminated glass, to provide durability and safety. We also offer different glass finishes, such as clear, grey, and translucent, to suit your home’s aesthetic while maintaining excellent insulation properties.
Air Gap
The air gap between the glass panes is essential for effective insulation. We use a precisely measured air layer to deliver superior energy efficiency and noise reduction that meets and exceeds Australian standards. To prevent condensation, a moisture-absorbing desiccant is added to the frame’s base.
Internal Pane
The internal glass pane completes the unit, maintaining the air seal while offering clear, unobstructed views. Combined with the air gap, it helps trap warmth in winter and keeps your home cooler in summer, reducing the need for excessive heating and cooling.
What to look for in quality double-glazed windows
Glass Type
- Toughened Glass: Up to 5 times stronger than regular glass for added safety.
- Laminated Glass: Provides a Grade A Safety Glass rating for maximum durability.
- Toned Glass: Offers privacy with tinted finishes while maintaining insulation properties.
Glass Size
Optimal insulation is achieved with an air gap between 12mm and 20mm. Be cautious of manufacturers using smaller gaps (6mm to 12mm), as they reduce thermal efficiency. For even better insulation, air gaps can be filled with gases like argon.
Frame Material
Aluminium frames, like those used at Action Glass & Aluminium, are strong, durable, and resistant to warping or cracking. Our high-performance frames are engineered to provide long-lasting security and insulation.
Locking Mechanism
For superior protection against break-ins, opt for multi-point locking systems. These provide a more secure seal compared to single-point locks, which are easier to compromise.
