    CE Marking – A Mandatory Requirement

    window_02On July 1st 2013, it became mandatory for all manufacturers of windows and doors to apply the CE mark to products covered by a harmonised European standard – hEN. The CE Mark stands for European Conformity and it represents the manufacturer’s declaration that the product complies with all essential requirements. The CE mark is now a mandatory requirement for a multitude of construction products, in addition to windows and doors.

    Compliance with Legislative Requirements – No Opt Out

    To achieve CE Marking, window and door fabricators, sealed unit manufacturers and toughened glass processors must ensure that their products comply with legislation specific to their products such as EN 1279, EN 12150, EN 12600 and EN14351.

    The EU Construction Products Regulation (No. 305/2011) (CPR) lays down the harmonised conditions for the sale of construction products throughout the EU and the CPR is directly applicable, in its entirety, in UK law. It is backed by an enforcement process and there is no option for opt out.

    Double glazed windows marked with the CE logo are hEN compliant. This represents a statement by the manufacturer that the product is produced following an approved process, using compliant materials.

    Meeting the Requirements of the Construction Products Directive

    door_01CE marking confirms that the product meets the requirements of the Construction Products Directive which is intended to ensure that such products can be sold into the European with a reliable comparison of identified key performance characteristics of the product.

    When sourcing new windows and doors, buyers would be well advised to ensure that the replacement windows they purchase carry the CE Mark on the product or its packaging.

    Compliance With CE Marking Requirements


    It is important to be aware that CE marking is done on a self certification basis and as such it is not independent proof of the quality of the end product.

    There are several things a manufacturer must do in order to comply with CE marking requirements, including:

    1. Define the product ranges, e.g. casement window, vertical sliding sash window or, residential door.
    2. Define the specified required characteristics of the product:
      • Strength of all safety devices fitted on the product
      • Presence of any dangerous substances used in manufacture
      • Thermal performance, as defined by the product’s U value
    3. Compliance with the requirements of these characteristics must be demonstrated.
    4. Establish a Factory Production Control (FPC) process facilitating consistent quality in product manufacture.
    5. Produce a Declaration of Performance for the product.
    6. Apply the CE Marking logo & required detail to the product or its packaging.

    Documentation of Compliance for CE Marking

    The manufacturer must establish a technical file containing a product test report from a Notified Body, to demonstrate compliance with the relevant standards.

    Manufacturers will self certify that their products meet the requirements of the Construction Products Directive.
