CE Marked

The CE marking applies to all window manufacturers in the European Union, and is mandatory from February 2010. Cloustek has not been left behind, and complies with the UNE-EN 14351-1 which affects the production of all manual or motorized windows, exterior doors and roof windows.

What is the CE?

The CE marking facilitates the free movement of goods within the European Union by replacing the rules of each country to establish a common level of procedures and tests, which have as their ultimate goal, to offer the customer the expected quality of the product purchased.

So the EC is appointed as a technical passport it is the only valid accreditation to sell our product in the EU and be sure to offer the highest possible quality.

Must meet the CE?

To obtain the CE mark we had to meet the different points:

- Initial Type Testing (EIT): We conducted tests for each type of series we manufacture in an approved laboratory. This test should cover all the fabrications that are done with this series.

- Factory production control: Our studio sets, documents and maintains a production control to ensure that products on the market will be consistent with the stated performance characteristics.

- Declaration of conformity: Once we have achieved compliance, the workshop developed and subsequently kept a declaration of conformity, which authorizes us to set the CE marking.

- Labelling: Finally, we must properly label all windows and provide the customer a product manual.

Next, please find attached an example of the marking to have found our products.
