The SÄLZER window range offers aluminium or steel frames with narrow profile face widths designed to provide safety and the ability to integrate extensive and multi-function glazing.  Viewed from the outside they do not look like heavy duty secure elements manufactured to withstand potential threats. Functionally the windows can offer ventilation, thermal insulation, and natural daylight and can be designed to meet the overall architectural intent of the building project.
