Choice of Composition and Properties of Elements

Alux svetlobne kupole 5

Domes enable optimal flexibility and adaptation of the skylights to the configuration of segmented and uneven rooms; they are ideal for the natural lighting of all types of buildings where the roof is close to the illuminated rooms.


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.
