FEATURES & BENEFITS

Sash Horns

A subtle but important feature, our run through horns are integrated into the sash for a truly classic appearance. Unlike surface-mounted alternatives, these are part of the sash extrusion, providing a more genuine and aesthetically pleasing finish.

Mechanical Joints

We manufacture both mechanically jointed frames – ideal for conservation areas where traditional butt joints are required – and fully welded versions, which offer a seamless appearance and fast fabrication. Whatever the requirement, we have a solution to suit.

Slim Meeting Rail

A defining detail of any vertical slider is the meeting rail – and ours is exceptionally slim. With a sightline of just 37mm, it enhances the vertical lines of the window and maximises natural light, all while maintaining the window’s traditional appearance.

Deep Bottom Rail

Our sash windows come with a deep bottom rail option as standard, adding weight and proportion to the lower sash. This detail perfectly mimics original timber designs and gives the window a more authentic, heritage-inspired look.

Custom Finishes

Our vertical sliders are available in a wide choice of colours and woodgrain-effect foils – including heritage whites, greys, and authentic wood finishes. Dual-colour options are also available to suit both interior and exterior styles.

We also offer a full range of Georgian bars, astragal bars, and sash furniture to complete the traditional look.

ENERGY EFFICIENT & SECURE BY DESIGN

Behind the traditional appearance lies a high-performance modern window. The multi-chambered Spectus profile delivers excellent thermal insulation, and our sash windows are capable of achieving strong Window Energy Ratings and low U-values – especially when paired with our advanced glazing options.

Security is also built in. All vertical sliders are internally glazed, compatible with high-security locking systems, and meet PAS 24 standards when specified with the correct hardware.
