Special designs of exterior blinds
Exterior blinds can be placed in the Heluz lintel and mounted directly on the facade. For greater safety and easy access to the emergency exit, all types of exterior blinds with guide rails can be equipped with the Emergency system for immediate pulling up. Find out more about special designs of exterior blinds in the article below.

Blinds in the Heluz lintel

Last time, we presented you with variants of exterior blinds for narrow windows, with solar power or for windy environments. However, exterior blinds also have their own special designs - the first option is the Heluz lintel blinds, to which we dedicated a separate article. The Heluz load-bearing lintel replaces a conventional lintel - thanks to the system groove for attachment, it is possible to fit blinds with manual or electric control. It meets all insulation properties and does not limit you about the type of slats used.

Facade exterior blinds

Cetta 80 and Zetta 90 blinds can be mounted directly on the facade, in front of the window opening. Silent operation is guaranteed tanks to round rails with rubber guide. This variant is exclusively motor-controlled.

Emergency safety blinds with immediate pull-up function

Are you worried that in the event of fire or natural disaster you will not be able to pull the blinds up in time? The solution is the Emergency safety blinds - in the event of a threat to human life due to flood, fire or other sudden danger, this system uses a spring mechanism to immediately pull up exterior blinds and make the safe emergency route accessible. This version is particularly suitable for office buildings. The mechanism does not require electrical energy to operate, which ensures its function even in the event of power failure. It is available for all variants of the ISOTRA exterior blinds with guide rails.                                                

At ISOTRA, we put significant emphasis on safety. Did you know that we design our products for maximum safety of your children?

Vertical blinds: shading of angled windows, niches and horizontal surfaces
Vertical blinds don’t have to look like stereotypical stripes of light fabric on office windows. They are also perfectly suited to living rooms, which can both elegantly shade and divide them.
