Design.

Our Sheerline windows boast a sleek design with slim frames that allow for abundant natural light, catering to homeowners who seek uncompromising quality.
Sheerline a ultra-premium aluminium window system.
Construction.

The Classic window system features ultra slim 59mm sightlines that enhance the amount of natural light entering your home, resulting in a sophisticated architectural appearance.

Sheerline's patented construction technique utilizes threaded screws to securely join corners in precise alignment.
This eliminates any corner stepping issues, enabling each Sheerline window to be meticulously hand-tuned for optimal performance. The end result is a harmonious blend of subtle elegance and exceptional quality standards.
Security.

The Prestigesystem by Sheerline utilizes an innovative construction method to create exceptionally strong frames, maximizing the inherent strength of our aluminium windows.
Paired with our high security multipoint locking system, this ensures a safe and secure environment for you and your home. Unique features such as hinge protectors further enhance the security levels.
For the highest level of security, the Prsstige window system offers a beadless option, eliminating the need for separate glazing beads.
