A classical kind of sun protection is provided by roller blinds. You can find them in most diverse shapes and colours. With a layer on the back sunlight can be reflected and therefore unpleasant heating of the room can be avoided. Roller blinds protect as well against burglary and curious looks. (Rollo)
Side- or chain-hoist roller blinds (Seiten- oder Kettenzugrollos)
The easiest handling is provided by roller blinds with side- or chain hoist. Here, a circumferential endless cord respectively ball chain is fixed at a revolving spindle. As a result, you can pull the roller blind fabric up and down. This system needs little maintenance and is also easy-to-use for children.
Snap roller blinds (Schnapprollos)
Snap roller blinds are pulled down at the operating handle. By stopping at a desired position the spring, which is fixed in the spindle, is clamped. With a jerky movement the roller blind snaps back upwards. This system requires some patience and is accompanied by a certain wearout.
Roof pitches (Dachschrägen)
For roof pitches one likes to use a technically slightly modified type of the snap roller blind, and therefore a spring which permanently stays tense.
The extended weighting rod is hung up left and right in holders in order to avoid snapping upwards.
Electromotor
A very comfortable version is provided by the electromotor. It is often fastened in the roller blind box and turns the spindle. With big windows or in high altitudes this system is especially suitable, because the roller blinds can be rolled up and down by remote control.
