The NCS scheme is mutually recognized in Norway, Sweden and Denmark. If a company is certified according to the NCS scheme, the company can sell laminated and finger-jointed profiles to companies that have joined the window certification scheme DVV in Denmark, NDVK in Norway and the P-marking scheme in Sweden, respectively.

By the manufacture of quality windows and exterior doors for the Scandinavian climate, with high humidity and wet and windy conditions, it is very important that the lamination and finger jointing in wood is done to a very high standard and that suitable adhesives are used. The NCS scheme ensures that very high standards are observed as regards materials and processes, as well as internal and external quality controls.
