Aluminium Sliding Windows
An aluminium casement window is a smart, high-performance choice for modern homes. Its sash attaches to the frame by one or more hinges at the side, swinging outward to provide maximum ventilation and unobstructed views.
This sleek, slim-profile design makes it ideal for contemporary living, combining a tight weatherproof seal, stylish aesthetics, and effortless functionality.
About Aluminium Sliding Windows
Aluminium sliding windows are designed for seamless, effortless operation. With a smooth sliding mechanism, these windows glide open and closed horizontally, offering excellent space-saving benefits. Unlike casement windows that open outward, sliding windows don’t require additional clearance, making them ideal for smaller spaces or areas with limited room for window operation.
The sleek, minimalistic design of aluminium sliding windows provides unobstructed views and abundant natural light. Their durable aluminium frame offers excellent resistance to the elements, ensuring longevity and reduced maintenance requirements. With a space-efficient design, they maximize the available area, making them perfect for both residential and commercial settings.
While aluminium sliding windows offer smooth and easy operation, they can sometimes be less airtight compared to casement windows, as they rely on a sliding track that can have small gaps. This can result in less thermal performance, especially in extreme weather conditions. However, with the use of modern weather seals and advanced materials, these challenges can be mitigated to provide satisfactory insulation.
