They are an excellent choice if you need to shade larger glass surfaces. External PVC or ALU blinds are very popular as protection from the sun in more modern buildings because they fit perfectly into any design.
Their main task is to prevent unwanted light or heat from entering the room during the summer months and to protect the joinery from all weather influences and problems. The slats of the external blinds have slightly rounded corners and slide along the guides on each side. This choice of shades provides the possibility of good ventilation of the space while simultaneously controlling the light.
"By choosing a good manufacturer who will flawlessly manufacture and install your blinds, buying blinds for your facility is a long-term and smart investment in your facility."

They function on the same principle as internal blinds, except that the materials of all the parts that make up the blinds are more massive and much stronger. Regulating the angle of light penetration as well as raising/lowering the slats on the blinds is done from the inside. Via a string, using an electric motor on a button or a remote control.
Assembly
Blinds are very easily and quickly mounted like blinds. With external blinds with an electric motor, it is possible to install a sensor that will give a signal to the electric motor in case of strong wind, so that the slats are automatically stored in the box and thus protected.
