Choosing Aluminium Windows

Aluminium windows are a popular choice for homeowners in Canterbury due to their durability and modern aesthetic. When selecting aluminium windows, consider factors such as energy efficiency, style, and functionality. The right windows can enhance your home's appearance while providing excellent insulation.

So, when it comes to updating your home in Canterbury, aluminium windows are one of the smartest investments you can make. Renowned for their durability, modern look, and energy efficiency, they’re well-suited to the unique weather conditions of the Canterbury region. But with so many styles and features available, how do you choose the perfect aluminium windows for your home?

‍

Understanding Canterbury's Climate and Its Demands

Canterbury weather can be both beautiful and unpredictable. From frosty mornings and southerly winds to sunny afternoons and sudden rainfall, the region demands windows that can stand up to it all.

Aluminium windows are a top choice for this climate because:

• They don’t warp, swell, or rot like timber can.
• They require minimal maintenance.
• They’re naturally corrosion-resistant—ideal for coastal areas.
• They can be fitted with double glazing and thermal breaks to keep warmth in and cold out.

But not all aluminium windows are created equal. The materials, construction quality, and glazing options you choose will make a big difference in both comfort and long-term value.

Benefits of Aluminium Windows

Aluminium windows are resistant to corrosion and require minimal maintenance. They can be customised to fit any architectural style, making them a versatile option for both contemporary and traditional homes. Additionally, they offer excellent thermal performance, helping to keep your home warm in winter and cool in summer.

Thermal Efficiency Matters

Energy efficiency is a growing priority for Kiwi homeowners, especially with New Zealand’s updated building codes. If your home isn’t retaining heat well, your power bills can skyrocket in winter.

Modern aluminium windows often include:

• Thermally broken frames: These reduce the transfer of cold from the outside by placing a non-conductive barrier between the inner and outer sections of the frame.
• Double glazing: Two panes of glass separated by an air or argon gas layer to improve insulation.
• Low-E glass: A coating that reflects heat back into your home while letting in natural light.

Together, these features can significantly reduce heat loss, improve comfort, and help meet the H1 energy efficiency standards for New Zealand homes.

Style and Functionality: What’s Right for You?

Every Canterbury home has its own character. Whether you’re living in a classic villa in Merivale or a sleek new build in Rolleston, you’ll want windows that match your style while offering practical benefits.

Here are some popular aluminium window styles:

‍

Awning Windows

Hinged at the top and opening outward, these are perfect for ventilation, even during light rain. Great for bathrooms, kitchens, and bedrooms.

‍

Sliding Windows

Ideal for spaces where you don’t want a window swinging open, like patios or tight exterior areas. They’re simple and low-profile.

‍

Picture Windows

Fixed, non-opening windows that bring in maximum light and uninterrupted views. Best paired with other open windows nearby.

‍

Choosing the right window style isn’t just about looks—it affects airflow, access, and light levels in your home. We recommend walking through your home with a window specialist to plan based on sun orientation and daily use.

‍

Customisation and Colour Choices

Modern aluminium windows come in a wide range of powder-coated colours and finishes. Whether you prefer a classic white, sleek black, or earthy tones that blend with the Canterbury landscape, there’s a shade to match your exterior and interior palette.

At Number One Windows & Doors, we offer:

• Matte, gloss, and textured powder-coat options
• Timber-look finishes for those who want the warmth of wood without the maintenance
• Custom glazing options, including tinted, obscure, and laminated glass for privacy or safety

‍

Don’t Forget the Hardware

Hardware is often overlooked, but it plays a huge role in functionality and security. Quality locks, handles, and hinges enhance both appearance and performance.

Look for:

• Corrosion-resistant handles and locks (especially important in coastal areas)
• Smooth sliding tracks and low-profile sills
• Optional child safety restrictors or keyed locks for peace of mind

All of our hardware options are tested for NZ conditions and can be tailored to your window style and finish.

‍

Local Manufacturing and Installation: Why It Matters

Canterbury homes benefit from working with local suppliers who understand the unique demands of the area. Locally made aluminium windows are built for New Zealand conditions and offer better lead times, service, and warranty support.
