The Regulation

From the 1st July 2013, the Construction Products Regulation (CPR) will replace the Construction Products Directive (CPD).

Under the new CPR products covered by a harmonised European Standard (hEN) will require mandatory CE marking

CE marking indicates that a product conforms to the legal requirements as specified in the European Assessment Document (EAD).

Installers sourcing complete units (window frames and Insulated Glass Units (IGU)) from a single supplier do not need to CE mark the product unless marketed under their own trade name. The frame and windows will be CE marked by the manufacturer.

Installers who source window frames and IGU’s from different suppliers need to make their own Declaration of Performance (DOP) and CE mark the window.

Installers, if classified as a micro-enterprise (turnover/balance sheet less than 2 million euro and employ less than 10 employees) can make the DOP and CE mark the product without the need to refer to notified bodies.

If an installer is not classified as a micro-enterprise then a notified body must be used.

BWF members

Heritage properties and the renovation and repair of existing windows do not require CE marking.

Reddiseals and the Regulation

The following Reddiseals product ranges do not have a written harmonised European Standard (hEN) nor a European Assessment Document (EAD). Therefore, are currently exempt from individual CE marking.

  • Sash furniture
  • Casement furniture
  • Pulleys
  • Sash cord
  • Draft and weatherproof seals
  • Lead
  • Timber
  • Plastic beading

Window compliance – BS EN 14351 – 1

Annex – ZA of BS EN 14351-1 identifies 3 criteria for windows to comply with CE marking:

  • Dangerous substances (REACH requirement)
  • Load bearing capacity of safety devices (Threshold requirement)
  • Thermal transmittance (UK building regulations requirement)

Reddiseals component products do comply with the guidelines stated under REACH or Thermal Transmittance compliance categories.

With regard to Load bearing capacity of safety devices, all products that are defined as ‘restrictors and security devices’ are classed as non-load bearing and therefore do not fall within the category stipulated by the hEN.

Therefore, CE marking does not apply to any of these Reddiseals products individually.
