Everyone building a new home or renovating an existing one has encountered this dilemma. Both types of shading elements effectively protect the home from sun rays. But the decision on which shading type to choose is ultimately up to your preferences and requirements, as well as the configuration of your home. At Tehrol, we offer a wide variety of both types. Below, we present some of the features and advantages of both types of shading elements to help you decide.


All types of blinds are, of course, designed to prevent sunshine from entering the room, allowing for a comfortable and enjoyable stay. All types can be regulated so that we can adjust the amount of light coming into the room. The shading of the premises brings a few additional advantages. It protects the premises and enables privacy against curious onlookers. In addition, they can improve the thermal insulation of the room and act as a decorative element.

The main difference between external and internal blinds is the location of the assembly. The exterior type, of course, is placed on the outer side of the glass surfaces, and vice versa. Due to various locations for installation, the shading elements are also made of various materials, and can also offer a slightly different functionality.


Since internal blinds are installed in the room itself, they can have a significant impact on the well-being and the appearance of the room. They are available in various shapes and implementations so that they match the interior. They can be mounted in the window frame, onto the window frame, on a wall or on a ceiling.

Compared to the external type, their advantage is that they are securely positioned inside. Which means that they are not hindered by environmental effects, they require less cleaning and are not vulnerable to intruders.


External shading elements are more robust because they must be resistant to weather influences. For this reason, they also provide a certain level of additional security when lowered. In principle, they allow for more privacy, as they can completely prevent unwanted views from the outside. External shading is also an excellent sound and thermal insulator. During the summer, it effectively protects the room from heating by preventing the flow of heat through the windows. In winter, it works as an additional heat insulator to help you save on heating costs.
