Why Aluminium Double Glazed Windows & Doors Are a Smart Investment for Your Home
If you’ve ever noticed your home losing heat in winter or becoming unbearably warm in summer, the problem may be your windows. Standard single-glazed windows do little to insulate your home, allowing heat to escape in the colder months and trapping heat inside during summer. That’s where double glazed windows come in – a modern solution that enhances energy efficiency, reduces noise, and increases home comfort.
At Fairview Rodney, we specialise in aluminium double glazed windows designed to suit New Zealand’s climate. In this post, we’ll explore the benefits of aluminium double glazed windows and doors, how they work, and whether they’re worth the investment.
Contact UsWhat are double glazed windows and how do they work?
Double glazed windows consist of two panes of double glazed glass, separated by an air or gas-filled space (usually argon). This design acts as an insulating barrier, reducing heat transfer and noise pollution.
How are double glazed windows made?
- Two panes of glass are sealed together, creating an airtight space – referred to as double glazed glass.
- A spacer bar filled with gas (such as argon) is inserted to improve insulation.
The unit is sealed to prevent moisture from entering, minimising condensation on double glazed windows. - Aluminium frames are used for durability, ensuring a long-lasting and low-maintenance product.
- This process creates a window that is significantly more effective at retaining indoor heat and blocking external noise compared to single-glazed alternatives.
Advantages of Double Glazed Windows NZ
Switching to double glazed windows offers numerous benefits:
- Energy Efficiency – Reduces heat loss, lowering your power bills.
- Noise Reduction – Blocks external sounds, creating a quieter home.
- Improved Comfort – Keeps your home warmer in winter and cooler in summer.
- Minimised Condensation – Prevents moisture build-up on windows.
- Enhanced Security – Tougher than single-glazed glass, making break-ins more difficult.
These advantages make double glazed windows an excellent investment for homeowners looking to improve their property’s efficiency and value.
Do Double Glazed Windows Keep Heat Out?
Yes! Double glazed windows keep heat out during summer by reflecting external heat while keeping warmth inside during winter. This means your home stays comfortable all year round, without needing to rely heavily on heating and cooling systems.
How Do Double Glazed Windows Save Energy?
Because of their insulating properties, double glazed windows reduce the need for artificial heating and cooling. This means lower energy consumption and reduced power bills, making them a cost-effective and environmentally friendly choice.
