Sieger Legacy Window

Timeless Design, Modern Performance


The Sieger Legacy Window offers a classic timeless design inspired by traditional industrial steel framed windows. The metal window profiles have a full thermal break and hold a double glazed unit for modern performance levels. These steel-look windows can be used to replace existing steel windows, or create an elegant glazing design on new build projects and renovations.

Max Window Size: 600mm wide / 1400mm tall for side hung windows, 1400mm wide / 1400mm tall for top hung windows, 2100mm wide / tall for fixed windows

Glass Specification: glass thickness 24-28mm, double glazing with low e coating and argon gas filling

Weather Protection: full testing completed, air (4), wind (2400 Pa), water (9A)

The outer profile of the Legacy Window is very minimal and a good match for older, more traditional steel systems. Unlike older steel systems the Legacy System offers a durable finish that is easy to maintain and look after. The full thermal break and insulated glass also offer high levels of insulation which are better suited to modern projects.

Any glazing bars within the window frame are bespoke and optional. You could use this system as a simple minimal aluminium window without the integrated glazing bars should you so wish.

If glazing bars are included within the design we include ‘dummy spacer bars’ within the double glazed unit. The aluminium glazing bars are then applied on the glass (on both sides) which creates a much more authentic steel look design.

We have a large Legacy Window arrangement on show at the Sieger Showroom that is available to view. Simply contact the team to book your visit. If you would like a quotation for a Sieger Legacy installation contact us or click the links below to request a cost for your project.
