EXTERNAL ROLLER SHUTTERS
The review should help you to recognize the permissible limits of compliance and incompliance. At the same time the sheet will
help you with reasoning as regards any unjust claims of the clients.
External roller shutters comprise of many metal and textile elements with various material features and production tolerances.
Despite the optimally selected products, deviations from ideal function may occur even in case of new installation due to the
product tolerances.
The external roller shutters are permanently exposed to the effect of weather, particularly temperature, moisture content, wind,
and contamination. They have a great effect on the function and appearance of external blinds.
The deviations from the table values can be corrected by our technicians within a specific scope.
Please, be aware:
The specified limit values are created based on the actual state of technology, respective technical standards, and based on
many years of experience.
The table values are valid only for the external roller shutters within the permitted production dimensions available in our actual
technical catalogue.
