CE Marking - Certification
The CE marking confirms that the product that bears it may be traded freely and be sold in the countries of the European Union. In addition, the CE marking certifies that the product meets all the standards and requirements set by the EU (CE).
The CE marking is awarded by the manufacturers of each product, who are pledging with their signature that they have complied with all the requirements set by the EU and that they implement and maintain a production control system at their factory or business, which ensures the quality of their products, as certified by the independent TÜV body with ISO 9001 Certificate.
DAUWIN® measures and monitors with daily checks the quality of the products manufactured, and the results of the corresponding measurements are released to a special independent body. In order to obtain an approval of the CE marking, the company must declare that its door & window frames have achieved the following properties: wind permeability, water tightness, resistance to wind load, water tightness in torrential rain, heat insulation, soundproofing, escape of hazardous substances (from the inside). In this way, the consumer knows that DAUWIN® products that bear the CE marking combine all the properties they claim to have.
