Sheerline Aluminium Systems Classic aluminium windows are designed to offer slim sightlines, exceptional thermal performance, and refined aesthetics across a range of architectural styles. Manufactured in the UK, the Sheerline Classic system allows you to choose from multiple profile designs — giving you complete control over the look and character of your windows.
From clean, modern lines to more traditional stepped detailing, each profile delivers the same high-performance aluminium construction with its own unique visual appeal.
Contemporary Profile
Clean lines and modern aluminium styling
The Contemporary profile features flat, minimalist lines that create a sleek and understated appearance. Designed to maximise glass area and natural light, it’s ideal for modern homes, extensions, and new-build projects.
Contemporary Flush Profile
Modern design with a flush internal and external finish
Contemporary Flush offers the same clean, modern styling as the Contemporary profile, but with a flush sash that sits neatly within the frame. This creates a smooth, seamless appearance both internally and externally.
Stepped Profile
Traditional character with added depth and definition
The Stepped profile introduces subtle detailing and depth to the frame, creating a more architectural and heritage-inspired look. It echoes classic window proportions while retaining the strength, slimness, and performance benefits of aluminium.
Stepped Flush Profile
Heritage styling with a refined flush finish
Stepped Flush combines traditional stepped detailing with a flush sash for a balanced and elegant appearance. The result is a window that feels timeless and authentic, while still benefiting from modern aluminium performance.
