On 1 July 2013, the Construction Products Directive was bindingly replaced by the new Construction Products Regulation. Due to its legal form, the Construction Products Regulation applies equally in all member states. With their introduction, the CE marking has been uniformly regulated throughout the EU. Previously valid national regulations have been dropped. Thus, the CE marking is also binding in all member states.

The declaration of performance replaces the old declaration of conformity. The key difference is that the declaration of performance must be created not just for specific product types, but for each individual product, resulting in increased manufacturer effort. In WINSLT^® is integrated the creation of a declaration of performance. After carrying out the calculation in WINSLT^®, the corresponding declaration of performance can be printed. The technical values from the calculation are transferred to the declaration of performance.
