Light bands

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.


Opening Systems

In the case of skylight bands only every other element can be opened.

Light Bands without Opening

In accordance with the needs of clients we also offer fixed skylights. 


Choice of Options for Opening Mechanisms, Drives and Controls

Opening Mechanisms

All elements of the skylight bands that are intended to be opened have additionally installed opening frames and hinges, which enable the opening and closing of the skylight band.

Combination

The simultaneous use of opening systems for ventilation and for the natural smoke and heat exhaust is possible.


Type of Opening Drive

Manual Opening

The simplest and cheapest opening system. Independent use is suitable solely for ventilation needs. It is used where the height from the floor to the skylight does not exceed 5m. It consists of a telescopic spindle and handle. 

Electrical Opening

For ventilation needs, electric motors with 230V and 24V voltage are used, which standardly enable the lateral raising of the skylight to various heights (standardly from the height of 300mm to 1000mm). Opening with electric motor opening mechanisms is available in different versions. 
The selection of the type of electric motor depends on:

  • the purpose of the skylights – ventilation, natural smoke and heat exhaust,
  • the dimensions of the skylights – with regard to the weight of the skylights and their load-bearing capacity.

Pneumatic Opening

Pneumatic opening is especially suitable for rooms with high specific humidity and filth, because electrical opening is harder to perform under such conditions. It is mostly used in rooms that contain compressed air, because in order to perform pneumatic opening one needs the supply of compressed air from 4–8 bars (primary installation). 
Pneumatic cylinders are standardly used for pneumatic opening. If several skylights for ventilation are installed on the same building, each skylight can be opened separately or several skylights can be opened simultaneously.
Pneumatic opening is suitable for ventilation; it can also be combined with a mechanism for smoke and heat exhaust in case of fire.
