Composition of Elements

Bauhaus Zagreb 2

Alux light bands are larger skylights that easily provide intense natural lighting in buildings with large open rooms. The skylight bands are linear skylight elements, constructed in optional lengths. They can be installed on any roof structure. They provide particularly intense lighting in galleries, studios, workshops, warehouses and in industrial, public and commercial buildings.


Transparencies and Colours of Skins

Choice and Adjustment of Colour for Greater Architectural Possibilities and Freedom

The daylight supplied to the room through a skylight can be adapted with the type of material used for the dome.

Skin Materials

Acrylic glass

Acrylic glass is coloured, colourless, translucent or semi-translucent.  
The Aglas Shade material has a specific colour and transparency: since the material effectively reflects IR-heat rays, it partially reaches into the red part of the visible spectrum, thus making the skin look somewhat rosily iridescent on the outside and give off a greenish light on the inside.

Single-Wall Polycarbonate

Sheets are coloured and colourless, translucent or semi-translucent.  

Multi-Wall Polycarbonate

Due to the inner structure with reinforcement ribs, the surface is covered with special parallel lines. Sheets can be transparent with highly visible ribs or translucent, where the ribs are much less distinct.
Sheets are coloured and colourless, translucent or semi-translucent.

Degrees of Luminous Transmittance

The degrees of transmittance depend on the number of skin layers and the material used.
