Internal inspections & Proven quality

Our experts check the quality of the profiles on a daily basis. They test all characteristics of the raw materials, the extruded profiles and the finished window and door systems in accordance with the strictest European standards. Dimensions, colour, thermal stability, corner joints and compositions are verified at regular intervals.

Finished windows and doors are checked for air permeability, wind resistance and watertightness. These strict internal inspections ensure the exceptional quality of the Deceuninck profiles.

Deceuninck always undertakes to have its products certified even though this is not legally required. This demonstrates that Deceunick attaches great importance to quality. Numerous approvals from various bodies, including from the Belgian Union for Technical Approval in Construction (BUtgb), the so-called ATG approvals, as well as KOMO certificates issued by Kiwa and SKG, are the best proof of this. An overview of all technical approvals at our disposal can be found on the website.


Certified product and installation

Mandated accredited certification bodies, such as Kiwa in Belgium, exercise external control over the conformity of production with the published approval at a specified frequency. Within this scope, quality certification agency Kiwa has developed an industry-specific quality label (SSK) in collaboration with Deceuninck. This quality label goes way beyond the European CE standard and provides even greater certainty that both the production (SSK 2001) and the installation (SSK 2002) of the window and door systems take place in a skilful manner. The scope of the accreditation is extended at regular intervals. This ensures that we continue to comply with the increasingly strict market demands.
