As the frame widths and the glass surface size may be different even with window sizes of the same size, it is recommended to order pleats as much as possible at all times. This ensures that they also fit perfectly and can fulfill their purpose well.
Most manufacturers on the Internet offer the production of pleats accurate to measure. However, you should always keep an eye on the ratings of the respective manufacturer, and see if other customers complain about deviations.
If a manufacturer often delivers inaccurate or incorrect measurements according to customer reviews, it is better to use another manufacturer. The trouble with not exactly matching pleats is otherwise great, and reversals and complaints are usually quite complex.
Custom-made pleats are also available for specially shaped windows. There are usually four basic shapes for pleats:
Rectangle (for all normal rectangular windows)
- With these shapes, you can usually cover all special shapes in windows, as you can see the length of each single edge when pleating can freely determine. The manufacturers then deliver the respective shape with the specified dimensions, the fastening materials are matched in length to it.
When you measure your windows, you must pay attention to a few things.
Depending on the method of attachment
Depending on how you want to fasten your pleated fabric later, you must determine different values during measurement. This is particularly important because the dimensions for individual types of fastening can be quite different. Im If in doubt, be sure to ask the manufacturer again where you need to measure accurately, or have a sketch made. Dimensional errors are at your expense. If your plisse does not fit, you usually can not claim reimbursement if you've measured yourself.
For many pleats, you must also consider a corresponding rear ventilation. In the case of non-darkening pleats, the required ventilation distance is usually about 3 mm, with darkening pleats at least 5 mm.
In the case of thermal insulation glazing, the minimum distance is greater, that is, you must maintain a distance of at least 10 mm from the plisse to the heat protection glass. Otherwise, the heat accumulation between the plisse and the heat protection glazing may lead to glass breakage.
In addition, it is generally the case that the frame distance (between the glass edge and the frame of the plisse) should generally be at least 15 mm. Obtain these values and the right measuring method (glass-fold-glass-edge-oblique folds) before ordering, however, exactly at the respective manufacturer in order to avoid misunderstandings and measuring errors in any case.
