How to choose? A Guide to Understanding All Types of Aluminium Alloy Doors and Windows

Types of aluminium alloy windows and doors include:

Casement windows
Casement windows are hinged on one side and can open outwards or inwards. They are operated using a crank handle or lever. They offer excellent ventilation as they can be fully opened to allow maximum airflow. Casement windows are a popular choice for areas where unobstructed views are desired, since their sashes do not overlap when open. They also provide a tight seal when closed, enhancing both energy efficiency and security. Aluminium casement windows are available in single or double configurations and can be customized to fit various opening sizes.

Sliding Windows and Doors
Sliding windows and doors are ideal for saving space, as they operate by sliding horizontally along tracks. This makes them perfect for areas where there is limited space for sashes that open inwards or outwards. Sliding windows are easy to operate and provide good ventilation, while sliding doors are ideal for connecting indoor and outdoor spaces such as patios, decking areas, and gardens. Aluminium sliding windows and doors feature smooth-gliding mechanisms that ensure effortless operation, even with large panels. They are available in various configurations, including two-, three-, or four-panel designs, and can be customized with different glass options and frame finishes.

Awning windows
Awning windows are hinged at the top and open outwards from the bottom. This creates an awning-like effect, allowing ventilation even during light rain, as the sash acts as a shield to prevent water from entering. They are often installed high up on walls to provide privacy while still allowing natural light and fresh air into the room. Aluminium awning windows are durable and easy to operate, with crank handles that make opening and closing effortless. They can also be combined with other window styles to create unique and functional arrangements.

Tilt-and-turn windows
Tilt-and-turn windows have two modes of operation. They can be tilted inwards at the top for ventilation, or swung inwards from the side like a casement window to provide full access. This makes them highly functional, allowing for easy cleaning from the inside and flexible ventilation options. Aluminium tilt-and-turn windows are renowned for their robust security features, with a multipoint locking system that offers enhanced protection when the window is closed.

French doors
French doors are a classic and elegant option consisting of two panels that swing open from the center to create a wide opening connecting indoor and outdoor spaces. They are commonly used for accessing patios, gardens or balconies, and can also be used as interior doors to separate rooms while maintaining an open and airy feel. Aluminium French doors combine the timeless beauty of traditional French doors with the durability and performance of aluminium alloy. They are available with various glass options, including clear, frosted or decorative glass, and can be customized with different frame finishes to match the home’s decor.

Bifold doors
Bifold doors are a stylish and space-saving option consisting of multiple panels that fold back against each other to create a large, unobstructed opening. Ideal for connecting living areas to outdoor spaces, they can be fully opened to blur the line between indoors and outdoors. Aluminium bifold doors are lightweight yet strong, ensuring smooth operation even with a large number of panels. They are available in various configurations, with panels that fold to one or both sides. They can also be customised with different glass options and frame finishes to suit individual preferences.

Factors to Consider When Choosing Aluminium Alloy Windows and Doors
Material quality
When selecting aluminium alloy windows and doors, it is important to consider the quality of the alloy used. High-quality alloys are stronger, more durable and more resistant to corrosion than lower-quality ones. Additionally, check the thickness of the frame profiles, as thicker profiles generally provide better structural integrity and thermal performance.

Thermal performance
Energy efficiency is a key consideration, so evaluate the thermal performance of the windows and doors. Look for frames with thermal breaks, as these significantly reduce heat transfer. The thermal performance of windows and doors is often measured by their U-value, which indicates the rate of heat transfer: A lower U-value indicates better insulation. When comparing different products, look for those with low U-values and consider upgrading to double or triple glazing with low-E coatings and gas fills to enhance energy efficiency further.

Glass options
The type of glass used in aluminium alloy windows and doors significantly impacts their performance in terms of energy efficiency, security, noise reduction and privacy. Clear glass is the most common option, but many other choices are available, including:
– Low-E Glass: This glass has an invisible, thin coating that reflects heat back into the room in winter and blocks heat from entering in summer, thereby improving energy efficiency.
– Frosted or obscured glass: This glass provides privacy while still allowing light to pass through, making it ideal for bathrooms, bedrooms or other areas where privacy is important.
– Laminated glass: Laminated glass consists of two or more layers of glass bonded together with a plastic interlayer. It is shatter-resistant, providing enhanced security and safety, and it also helps to reduce noise transmission.
– Double or triple glazing: This consists of two or three panes of glass separated by a spacer and filled with air or an inert gas such as argon or krypton. They provide better insulation and noise reduction than single glazing.

Security features
Security should be a top priority when choosing windows and doors. Look for aluminium alloy windows and doors fitted with high-quality security hardware, such as multi-point locking systems which secure the sash at multiple points around the frame, making them much harder to force open. Reinforced hinges, anti-lift devices and shatter-resistant glass are also important security features to consider.

Style and design
The style and design of aluminium alloy windows and doors should match the look of your home. Think about the shape, size and configuration of the windows and doors, as well as the colour and finish of the frames. Choose a style that looks good and suits your needs. This could mean making sure there is enough air circulation, natural light or access to outdoor areas. Many manufacturers offer custom design options.

Budget aluminium alloy windows and doors are available at a range of prices. So, it is important to set a budget before you buy. The cost depends on things like size, style, material quality, glass options and security features. Although the cheapest option may seem like the best deal, it’s better to spend more on high-quality aluminium alloy windows and doors. This will save you money in the long term because they use less energy and last longer. When you’re deciding, think about the overall value, not just the price.

Who makes and supplies the product
It is very important to choose a good manufacturer and supplier. This will make sure you get good-quality aluminium alloy windows and doors and a reliable service. Look for companies that have a history of making good products, offering good guarantees and helping their customers. A good supplier will help you choose the right windows and doors for your home and make sure they are installed properly.
