Cover box

The top cover box can be visible in classical external blinds. In new constructions and adaptations, the top box can be covered with the final plaster.

Slats

You can choose from different forms of slats, which can be inserted into all TEHROL external venetian blind systems.

C slat

  • Basic slat shape. 
  • The slats are made of aluminium, permanently resistant to rust.
  • Tested for strong wind shocks.
  • Easy cleaning of slats.
  • A wide selection of colour shades.

T slat

  • Basic slat shape.
  • The slats are made of aluminium, permanently resistant to rust.
  • Tested for strong wind shocks.
  • A wide selection of colour shades.

S deluxe slat

  • An updated, sophisticated and more elegant design.
  • The shape of the slats achieves optimal sunray deflection.
  • The inserted seal allows for better sealing, resulting in better resistance to wind conditions.
  • The slats are made of aluminium, permanently resistant to rust.
  • Easy cleaning of slats.

Z slat

  • An updated, sophisticated and more elegant design.
  • The shape of the slats achieves optimal sunray deflection.
  • The inserted seal allows for better sealing, resulting in better resistance to wind conditions.
  • The slats are made of aluminium, permanently resistant to rust.

Terrace and balcony shading

External venetian blinds can be used to dim or close off balconies and terraces that are not glazed.

Wire rope

Instead of the classic guide rails for the gliding of the slats, we can implement a wire rope on the sides of the blinds.

Colours

You can customize the colour of the external venetian blind system to suit your facility. All the guide rails the slats travel along, as well as the box, come in any colour from the RAL colour scale, according to your preferences and requirements.

Integrated insect screen

The integrated insect screen can be installed in all types of external venetian blind systems, or a SCREEN fabric can be inserted instead.

Control

The blinds can be operated manually or by an electric drive. The TEHROL system enables the fully automatic control of external blinds.

External venetian blinds, when lowered, prevent the heating of the glass and thus the direct entry of heat into the room. In winter, they work as an additional heat insulator to help you save on heating.

Aluminium slats help improve sound insulation. This has two advantages. Firstly, there is less noise coming from the outside. This will help you go to bed in the evenings or let you sleep in, even with noisy neighbours. Secondly, of course, the insulation works both ways. Closing the external venetian blinds reduces the possibility of neighbours or passers-by listening in on your private conversations.

A fully lowered venetian blind acts as an effective protection against intruders. It is very important that any intruders are deterred before even attempting a break-in.

All the components exposed to external weather conditions are made of aluminium material resistant to external influences.
