Aluminium windows are now one of the most popular choices for modern homes and buildings. They are strong, lightweight, resistant to weather, and easy to look after. Aluminium windows also offer a clean and contemporary look that fits many architectural styles. Thanks to advances in design and engineering, there are many types of aluminium windows available, each suited to different spaces, ventilation needs, and aesthetic preferences.
In this guide, we’ll explain the main aluminium window types, how they work, and where they are best used. Whether you are designing a new home, renovating an old one, or choosing replacements, this article will help you make a confident decision.
Why Choose Aluminium Windows
Before we look at the different types, it helps to understand why aluminium is a preferred material for window frames.
Strength and Durability
Aluminium is a metal that is naturally strong and resistant to rust and corrosion. This means aluminium windows can withstand varied weather conditions without losing shape or performance.
Low Maintenance
Unlike wood, aluminium does not decay with moisture or insects. It only needs occasional cleaning with soap and water to stay in good condition.
Slim and Modern Look
Because aluminium is strong, frames can be made thinner while still holding large glass panels. This creates a sleek look and brings in more natural light.
Flexible Design Options
Aluminium windows can be made in various shapes, opening styles, and configurations to suit different rooms and functions.
Common Types of Aluminium Windows
Here are the most widely used aluminium window types for homes and buildings:
1. Sliding Aluminium Windows
Sliding aluminium windows have panels that slide horizontally along tracks. This makes them very practical for many rooms.
Features
- Smooth horizontal movement
- Easy to operate
- Saves space
Best for
- Small rooms or apartments
- Living rooms and bedrooms where space is limited
Sliding windows are popular because they are simple and strong. They do not swing outward or inward, so they are perfect for areas next to walkways or patios.
2. Casement Aluminium Windows
Casement aluminium windows are hinged on one side and open either inward or outward like a door. They are good for ventilation and strong sealing.
Features
- Hinged opening
- Allows full airflow
- Often has secure locking systems
Best for
- Kitchens and bathrooms
- Bedrooms and study rooms
- Areas prone to wind or rain
Casement windows are great where you want to direct airflow into the room. When closed, they seal tightly and help reduce noise and dust.
3. Fixed Aluminium Windows
Fixed aluminium windows do not open. They are used mainly for letting in light and offering views.
Features
- Do not operate (no opening)
- Large glass areas
- Minimal design look
Best for
- Stairwells
- Hallways
- Large wall areas where ventilation is not needed
Fixed windows are ideal for spaces that need plenty of light but not airflow. They can also be paired with other types of windows.
4. Tilt and Turn Aluminium Windows
Tilt and turn windows are designed to open in two ways. They can tilt at the top for gentle airflow or swing open like a door from the side.
Features
- Dual function (tilt or turn)
- Easy to clean from inside
- Secure and airtight seal
Best for
- High rise apartments
- Living rooms or home offices
This type provides flexibility. The tilt mode allows fresh air without fully opening the window, and the turn mode allows full access for cleaning and ventilation.
5. Awning Aluminium Windows
Awning windows are hinged at the top and open outward from the bottom.
Features
- Opens outward from the bottom
- Allows ventilation even during rain
- Commonly placed high on walls
Best for
- Bathrooms
- Kitchens
- Areas where ventilation is needed without letting in rain
Awning windows are useful in climates with frequent rain. They allow air to come in even when it is wet outside.
6. Louvered or Louvre Aluminium Windows
Louvered windows have multiple horizontal slats that can be tilted to control airflow and light.
Features
- Adjustable slats
- Control of light and air
- Provides privacy and shade
Best for
- Bathrooms
- Utility rooms
- Storerooms or basements
Louvered windows are ideal where constant airflow is important but direct sunlight or rain should be reduced.
7. Bay Aluminium Windows
Bay windows extend outward from the main wall. They often combine fixed and operable windows to create more interior space.
Features
- Projects outward
- Offers panoramic views
- Adds interior shelf space
Best for
