In other words, it is for example possible to select the position of the blind system such that the blind system does not cover a specific area of a transparent sheet between the upper profile of the blind system and the upper — profile of the glazing unit. This is for example advantageous in the Nordic Countries, where the sun may be very low for a period of time. According to conventional blind systems, the blind has to be lowered from an upper part of a transparent sheet to the lower part of the transparent sheet in order to protect a person from the direct light of the sun, and thus the transparent sheet is completely or nearly completely covered with the blind in such a case. This may lead to a very dark room or space behind the blind. According to an embodiment of the present invention, a distance between the upper profile of the blind system and the upper profile of the glazing unit can be selected, for example increased. Thus, it is possible to cover a lower area of a transparent sheet of a glazing unit, while simultaneously an upper area of the transparent sheet of the glazing unit is not covered, and — thus light can pass into the room or space behind the blind and at the same time a person is protected from the direct light of the low sun.

[0021] Further, some parts of the fastening system can be made of plastic material and be produced by injection molding, for instance. Thus, it is possible to manufacture a S large number of fastening systems in a specific period of time and the production of the 1 25 — fastening systems is cost efficient. > [0022] According to certain embodiments, the fastening system can serve at least z partially as a closure for the end of the hollow profile, thus preventing liquid from flowing I into the hollow profile. 2
