How Aluminium Windows Perform in New Zealand’s Diverse Climate

New Zealand’s coastal and harsh environments pose unique challenges for building materials, and aluminium windows are an excellent choice for properties located in these areas. Due to their strength, durability, and versatility, aluminium windows can withstand the demanding conditions of coastal regions, including saltwater exposure and high winds.

Hinged aluminium doors are doors that open outward or inward on a set of hinges, much like traditional wooden doors. Unlike sliding or bi-fold doors, hinged doors are hinged on one side and swing open on their axis. Aluminium makes these doors more lightweight yet strong, offering greater security and energy efficiency compared to traditional timber or steel doors.

These doors are available in a variety of styles, from single to double doors, and can be equipped with various glass panels or decorative elements to suit your home’s style. Whether you choose a minimalist look or one with more detailed features, hinged aluminium doors are a versatile option for any property.

1. Saltwater Resistance
   Aluminium is naturally resistant to rust, making it a suitable material for coastal environments where saltwater exposure is prevalent. However, saltwater can cause corrosion over time if not properly protected. Aluminium windows in coastal regions need to be treated with coatings or finishes that offer additional protection against the corrosive effects of salt air.

The natural oxide layer that forms on aluminium provides some protection, but in coastal areas, it’s essential to use windows with corrosion-resistant coatings to ensure their longevity. Aluminium windows that have been properly anodised or powder-coated are particularly effective in resisting saltwater damage.

2. Wind Resistance
   Coastal areas in New Zealand often experience strong winds, and aluminium windows are well-suited to handle these forces. Aluminium frames are known for their robustness, making them a reliable choice for properties in high-wind zones. The material’s strength means it can support larger panes of glass, allowing for greater views without sacrificing durability.

Windows in coastal environments should be installed with appropriate seals and weatherproofing to ensure they remain secure and functional, even during storms. Proper installation is key to preventing damage caused by high winds.

To ensure that aluminium windows withstand the challenging coastal conditions of New Zealand, several factors need to be considered beyond just the material and coatings:

1. Proper Installation
   Proper installation is crucial for ensuring the durability of aluminium windows in coastal environments. Gaps or poorly sealed windows can lead to water ingress, which can cause damage to both the windows and the building structure over time. Professional installation ensures that the windows are fitted with high-quality seals, weatherstripping, and drainage channels to prevent water and salt from penetrating.
2. Regular Maintenance
   Although aluminium windows are low-maintenance, regular cleaning and inspection are still important, particularly in coastal areas. Salt build-up can accumulate on the window frames, leading to corrosion if not cleaned regularly. Use fresh water to rinse off salt deposits and check for any signs of wear or damage to the coatings. Keeping the frames and seals clean will extend the lifespan of the windows and maintain their performance.

3. Reinforced Frames
In areas with extreme wind conditions, consider aluminium window frames that are specifically designed to handle high wind loads. Reinforced frames offer additional strength and stability, ensuring that the windows remain secure and functional during storms or strong winds, which are common in coastal environments.

1. Wind and Impact Resistance
   Coastal areas can experience high winds and storms, so it’s crucial to choose windows that are designed for wind resistance. Impact-resistant glass and reinforced window frames are essential to ensure that the windows can withstand strong gusts and flying debris.
2. Moisture Protection
   Moisture exposure is a constant concern in coastal environments, and aluminium windows must be properly sealed to prevent water from entering the building. Install windows with weatherproof seals that protect against wind-driven rain and humidity, ensuring the interior of the property remains dry and comfortable.
3. Choosing the Right Glass
   Double-glazed windows are an excellent choice for coastal areas, as they provide an extra layer of insulation, soundproofing, and protection against heat transfer. Additionally, low-emissivity (Low-E) glass can be a great option, as it reduces UV exposure and protects the interior of the property from fading due to the sun’s rays.
4. Compliance with Local Regulations
   When installing aluminium windows in coastal or harsh environments, it’s important to ensure the windows comply with local building codes and regulations. New Zealand’s coastal building codes may include specific requirements for wind resistance, saltwater corrosion protection, and other environmental factors. Consulting with professionals will ensure that your windows meet these standards for optimal performance and safety.

Aluminium windows are an excellent choice for properties in New Zealand’s coastal and harsh environments, offering durability, strength, and resistance to corrosion and wind. By selecting the right finishes, ensuring proper installation, and maintaining your windows regularly, you can ensure their longevity and performance in these challenging conditions. Whether you’re protecting your home or business from saltwater exposure, high winds, or extreme temperatures, aluminium windows provide a reliable and aesthetically pleasing solution.
