Advantages and disadvantages Blinds

In addition to the total darkening, you can also influence the incident light intensity by raising or lowering the shutter. In addition, blinds also provide protection against heat and cold, so they can insulate a room to some degree against unwanted temperatures. The same applies to the sound. As burglar protection, they are usually only partially suitable because broken up very quickly. Price is the effort rather high.

Venetian blinds and pleats


Venetian blinds refer to individual, interconnected lamellae, which can usually be adjusted via rods or cords. The installation is very simple and takes place on the window frame (side guide) or above the window (lintel).


Pleats have the same effect, but are rolled up. Thus, the light incidence can not be influenced so accurately. There is only the possibility to completely or partially close pleats, with the unlocked window area completely unprotected (looks, heat, etc.).

Pros and cons pleats and blinds

Price wise, pleats and blinds are cheap, and can be relatively costly for individual and very special products (for example, especially for photo labs).

To insulate the window, special insulating films, especially for single glazing or box glazing, are well suited to achieve significantly better thermal insulation values.

The assembly is easy, as well as the removal. The prices for window films are also moderate. However, the cutting and sticking is much more labor-intensive than some other alternative to darkening.
