From 1 July 2013, the Construction Products Directive (CPD) was replaced by the Construction Products Regulation (CPR 305/2011), which makes it mandatory within the EU for construction products covered by a harmonised European standard to be CE marked.

The Declaration of Performance is a key part of the Construction Products Regulation. It provides information on the performance of a product. Each construction product covered by a European harmonised standard or for which a European Technical Assessment has been issued needs this Declaration and has to be CE marked. This helps increase transparency and improves the functioning of the Single Market.

We can therefore confirm that all Dakstra Roof Windows covered by a harmonised standard are CE marked according to the Construction Products Regulation.

To get the performance data relating specifically to your window, please use the drop-down list above to enter the information taken directly from the type sign plate at the top of the sash.
