MLL-Domelight darkening

Lecture halls, event rooms, churches, libraries or laboratories - the need to darken rooms for events is manifold. Different designs provide for variable installation. Whether with manual operation or quiet and comfortable motor technology. These internal MLL darkening systems are not only suitable for darkening, but also in combination with other materials, as internal sun and glare protection and are a sophisticated alternative to external shading.

A special highlight among the darkening systems is the MLL light dome darkening system, which was developed especially for higher window areas. This special darkening system does not require the usual guide systems, the fabric runs autonomously in an extruded aluminium housing. The sliding safety is guaranteed by the special brush guide and thus ensures a light-tight darkening. This type of darkening system is excellently suited in connection with smoke and heat ventilation systems.

MLL system structure:

The MLL-Lichtschutz dome light shading systems are available in the respective standard sizes. Depending on the area of application, up to six standard fabric variants are available with different colours and degrees of light transmission.

Advantages at a glance

  • Thermal insulation at high outside temperatures
  • Light and glare protection
  • Can be combined with geometric smoke extraction
  • Conveniently controlled by remote control (variable radio and control options)
  • Brush seal reduces residual light incidence and ensures optimum darkening quality
  • Fabric and colour variations or blackout wheel freely selectable
  • Flame retardant according to DIN 4102 B1/M1
  • Dirt-repellent
