Profiles and Design

The overall side profile of our aluminium sash windows is 81mm with a horizontal profile of 36mm and a frame depth of 114mm. The base frame height for ‘low line’ is 43mm while ‘traditional’ is 90mm tall. The double frame is 116mm wide externally and 88mm wide internally.

The aluminium framing can be powder coated any RAL colour of your choice. This allows you to match your windows with your current doors. The maximum sizes available are 1.6m wide and 3.3m high.

Ironmongery and Performance

Different ironmongery is available including a locking catch without a key, ring pulls, base sash retainers and scroll lifts. Each of these are available in a range of finishes including black, white, chrome and gold. The scroll lifts are only available on the ‘traditional’ sash windows.

All of our Sieger sash windows are tested for weather performance, security and thermal performance. Dummy vents can be integrated for non-opening windows and trickle vents are available to be integrated into the head frame. For a more traditional sash window design, integrate bespoke glazing bars to your design requirements. Hedgehog Aluminium Systems can also integrate sash restrictors with a default opening height of 100mm.
