Aluminum is the most durable, long-standing and resistant material of those used in enclosures. Aluminum has the strength and a durability of the things that last a whole lifetime.

TYPES OF ALUMINIUM WINDOWS

Aluminium windows have become a popular choice for homeowners due to their durability, strength, and modern look. There are several types of aluminium windows available on the market, each offering different benefits and features.

ALUMINIUM CASEMENT WINDOWS

One of the most common types of aluminium windows is the casement aluminium windows. They are hinged on the side and open outward and are available in various sizes and styles. They also feature a multi-point locking system for added security. Casement windows are perfect for those who want to maximise the amount of natural light entering the room.

ALUMINIUM SASH WINDOWS

Another popular type of aluminium windows are sash windows. These windows are composed of two sashes that move vertically within a frame. The aluminium sash windows can be opened at the top or the bottom, allowing for more control over the amount of ventilation in the room. The sashes also have counterweights which make them easier to open and close.

ALUMINIUM SLIDING WINDOWS

Aluminium sliding windows are also becoming increasingly popular. These windows are ideal for smaller rooms or for those who want to maximise the amount of natural light entering the room. The panels of the window slide horizontally, allowing for easy operation and more ventilation options. 

All types of aluminium windows are an excellent choice for homeowners who want to combine durability, strength and beauty in their windows. Contact us today and we will help you to choose the option that best suits your needs.
