Pleated blinds
As Plisseeanlage refers to a form of sun protection at the window, which is cognate with a roller blind. The material is not wound as the blind on a shaft, but it is pre-folded ( pleated) and is pushed together in concertina fashion to form a package. For plants, the names Pleated, Pleated Plisseevorhang or shortening are common.
Plisseeanlagen are very versatile in the field of interior sun protection, since they can be produced in many forms. Many geometric shapes can be made . In addition to rectangular systems, there are also trapezoidal, triangular or semi-circular Plisseeanlagen. The top and bottom rails of the system can also be movably mounted so that as required Plisseevorhänge shade only partial areas of the window. By incorporating further in the middle befindlicher, portable bars, the plants can also be equipped with several substances, the type of window covering can be changed as by a handle. This also allows the construction of day / night systems.
The operation of pleats done with handles, pull cords, pull chains or electrically. Tight and free hanging models are available for pleats. The biggest difference between these two types lies in the possible maximum dimensions within which a Pleated can be made . Pleated blinds are designed for vertical installation with a recommended maximum inclination, as is the case with bottom-hung windows in the open state. For larger inclinations, there are special solutions. So Dachfensterplissees are available, for example with lateral guide rails that support the system additionally. Especially for winter gardens are so-called ceiling systems available. These are manufactured with additional wire ropes and thus allow even a vertical mounting.
The fabrics used are divided into different degrees of transparency and can for example be perlmutbeschichtet to ensure good heat reflection while translucency.
A further development of Plisseeanlagen provide Wabenplisseeanlagen dar. Here the blind compared to conventional Plisseeanlagen is executed twice. The resulting cushion of air between the two connected, pleated fabric panels has a positive effect on thermal insulation and room acoustics. The constructive necessary for Plisseeanlagen perpendicular lines and punch holes remain hidden when Wabenplisseeanlagen between the panels. The possible field of application (windows forms, bracing) and the available colors and design patterns correspond to that of classical Plisseeanlagen. Disadvantage of Wabenplisseeanlagen other hand, is the more elaborate cleaning.
