CE Marking in general

Since 1 February 2010, all window and door manufacturers have been required to place the well-known CE marking on their products. The CE marking introduced with the Construction Products Directive is a direct consequence of the EU single market, which is intended to ensure the free movement of goods and services between member states. To turn the intentions into practice, various directives and regulations for different product groups have been prepared. Windows and doors are covered by the Construction Products Regulation (305/2011), which contains seven basic requirements to be satisfied by all construction works:

  •     mechanical resistance and stability
  •     safety in case of fire
  •     hygiene, health and the environment
  •     safety and accessibility in use
  •     protection against noise
  •     energy economy and heat retention
  •     sustainable use of natural resources

These requirements have been made tangible in so-called ”harmonised” standards. Read more about Idealcombi’s CE marking in the menu on the left.


In Denmark CE marking has been implemented directly into Danish law through: Construction Products Regulation (305/2011) PRODUCT STANDARD.
The harmonised standard applying to doors and windows is called: BS/EN 14351-1:2006 + A2:2016
Windows and doors - Product standard, performance characteristics - Part 1: Windows and external pedestrian doorsets

This standard does not apply to elements with fire resistance and smoke control characteristics nor does the standard apply to internal doors. The product standard provides information about how to determine various performance characteristics, e.g. acoustic performance, dangerous substances, air tightness, etc.
According to Annex ZA to the product standard, it is the legislation in the country where the product is marketed that determines which performance characteristics should be declared as a minimum. In Denmark this means that the manufacturer, through the CE marking, should as a minimum declare:

  •     Thermal transmission coefficient (U-value)
  •     Load-bearing capacity of safety devices
  •     Radiative properties – sun factor and light transmittance

and inform about the release of dangerous substances to the indoor climate.
