Where daylight and visibility matter, the ALU 40 excels. The door leaf is built from specially designed aluminium profiles that accept a huge range of field fillings — windows, aluminium cassette panels, and glazing in translucent, coloured, insulating or air-permeable versions.
Glazing sits in anodised aluminium glazing beads rather than plastic strips: more durable, dimensionally stable in warm weather, and individual windows can be replaced without changing a whole panel. For temperature-controlled buildings, a thermally separated Clima version with a continuous window seal is available.
