Building closures

In the past, all definitions and designations relating to building closures were covered by a single standard (NF P 25-101), but this is no longer the case, as national texts have been replaced by European standards.

The European working groups carried out their work separately, even though they were covered by the same technical committee (CEN/TC33).

It is now necessary to separate :

• Closures for openings fitted with windows, more commonly referred to as "residential closures", such as roller shutters, swing shutters, blinds, etc,

  and

• industrial, commercial and garage doors, formerly referred to as "open bay doors". This category includes all doors whose main function is to allow the passage of vehicles. Examples include garage doors, doors installed in industrial premises, etc. Grilles and metal curtains installed on store fronts, for example, fall into this category, even if their main purpose is to allow the passage of people, not vehicles. Normative and regulatory considerations, particularly in terms of safety, make it more consistent to treat these products in the same way as vehicle doors.
