CE Marking

The construction industry is facing the most significant change for a decade in the way in which construction products are sold in Europe. From 1st July 2013 it will become mandatory for manufacturers of windows, external doors and glazing products to apply the CE mark. This is a major change as CE marking is currently voluntary in the UK.

CE Marking

CE marking is a declaration by the manufacturer that the product meets all the appropriate requirements of the relevant legislation, by making this declaration the manufacturer assumes legal responsibility for the products conformity.

The ‘manufacturer’ classification applies to the person who places the product on to the market, an unglazed window or door frame cannot therefore be CE marked, in this instance the installer becomes the manufacturer, it’s important you explain this to your customers.

A product with the CE mark can be placed on the market of any European country, it is therefore considered a ‘passport’ for technical information relating to a construction product.


To prepare for CE marking your windows and doors must meet the requirements of product standard EN 14351-1, the applicable performance characteristics are listed below;

  • Water tightness
  • Dangerous substances (in relation to their indoor impact only)
  • Resistance to wind load
  • Impact resistance of glazed doors (with regards to risk of injury only)
  • Load bearing capacity of safety devices
  • Ability to release (applies to locked doors on emergency escape routes only; doors with panic hardware)
  • Acoustic performance
  • Thermal transmittance (U Value)
  • Air permeability

Crucially for the UK however we must only consider those aspects covered by building regulations, with this in mind CE marking could be possible simply by declaring;

  • that no dangerous substances are released under normal use
  • the threshold value for the load-bearing capacity of safety devices (350N), if fitted.
  • the U Value

Compliant test data can only be demonstrated by Initial Type Testing (ITT), with all testing being undertaken or approved by a Notified Body. To ease this potential burden the cascading of test data is permitted; from your system supplier to you the fabricator, from you to your installer.
Where the manufacturer has no data, for any performance criteria not covered by building regulations for example, you are required to state “npd” (No Performance Determined) next to each applicable characteristic.

The final but no less important requirement of CE marking is a form of quality management system covering the product’s manufacture, also known as Factory Production Control (FPC), something many WER users will already be familiar with.

Deceuninck are committed to ensuring that their customers have access to the data they need, our support should you need it could make the transition to CE marking a smooth one. To establish what Initial Type Test data can be cascaded to you and for guidance on what to do next, please contact our Technical Dept. Tel. 01249 810415.
