Fine lines and traditional detailing for steel-look windows with a distinctly architectural feel.
ALITHERM HERITAGE · BROCHURE INSPIRATION
Alitherm Heritage is a separate system developed for steel-look glazing. Its slim frames and optional horizontal glazing bars suit period-inspired schemes, loft-style interiors and carefully considered renovations. Discuss the original proportions of your windows with us before choosing a layout.
Compare layouts, then choose colours, glass and hardware in the designer.

The pattern matters as much as the frame colour. Compare the width and height of each light, the spacing of horizontal bars and how the design aligns with neighbouring windows. For an existing period frontage, photographs of the whole elevation help us discuss a coherent arrangement.
Overall dimensions, the number of opening lights, glazing specification, decorative bars and colour combinations all affect the quotation. Installation access, the condition of the opening and the extent of making good also need to be checked.
Use our estimate to compare design preferences. Send the selected design with photographs and the number of windows required for a more useful first discussion.

No. They are aluminium windows designed with a slim, steel-look appearance. The stepped profiles and optional glazing bars create a different look from a plain contemporary casement.
The illustrative starting price here is £1,095 including VAT for the specified 1200 × 1200 mm two-pane design. This is not a confirmed Spectrum price. Your required layout, bar pattern, glazing, finish and installation conditions will determine the quotation.
They may be an option, but first compare the frame proportions, opening arrangement and glazing-bar positions with the originals. For a listed building or a property with planning restrictions, confirm the necessary permissions before ordering.
No. Alitherm Heritage is a separate system. A Heritage-style sash within the Alitherm 400 family is a different specification. We will identify the system on your quotation so you can compare like for like.
