Schüco AWS Aluminium Windows Explained

By SDL Schüco Doors London Team Published 28 July 2026Focus: schuco doors

AWS stands for Aluminium Window System, Schüco's window platform. It runs from slim, cost-effective profiles up to high-performance, energy-focused depths, all sharing the same design language — which is why AWS windows sit so well next to Schüco doors.

Reading the AWS numbers

AWS models are named by construction depth in millimetres — for example a shallower system for standard replacements and deeper ones for low-energy builds. Deeper generally means better thermal performance and larger glass capacity. The right depth depends on your energy target, which ties directly into U-values.

Opening styles

AWS supports outward casements, inward tilt-and-turn, fixed lights and flush-fitting sashes. Which you choose changes cleaning, ventilation and looks — compare tilt-and-turn versus casement and consider a flush casement if you want the sash to sit level with the frame.

Sightlines and light

The appeal of aluminium is the thin frame. AWS slim options maximise glass and daylight, which matters in north-facing or smaller rooms. If minimal frame is your goal, read slim-sightline windows.

Specifying AWS locally

As with the doors, the fabricator matters. Schüco publishes the AWS technical range at Schüco UK, and in Hertfordshire the window systems are supplied and fitted by aluminium window specialists.
