Steel look aluminium windows with modern performance
The Sieger Legacy Window is a steel look aluminium window system designed for projects where traditional character needs to meet modern glazing performance. Inspired by classic industrial steel framed windows, the system uses slim aluminium profiles, optional bespoke glazing bars and a full thermal break to create heritage-style windows with improved insulation, security and durability.
Suitable for traditional homes, renovation projects, new builds, commercial interiors and steel look glazing packages, the Legacy Window can be specified as side hung, top hung, tilt and turn, fixed or multi-light casement window designs. It is a strong choice where the building needs timeless glazing character without returning to older steel systems.
Sieger Systems supplies and installs steel look aluminium windows across London, Buckinghamshire, Berkshire, Oxfordshire, Hertfordshire, Surrey, Bath, Bristol and Somerset.
