KÖMMERLING systems show superiority in all indicators.

Behind KÖMMERLING lies a nearly 40-year of history. This is 40 years of development. Entire institutes work to study and select new materials and create the highest quality products. The smallest detail has been considered and tested. Each gasket or screw is in place to give the best result. Details are important because they are relevant and affect the overall quality.

This is the reason why the German joinery gives very good results for all test indicators.

The most important for the consumers is the thermal insulation indicator. KÖMMERLING has almost 10% better thermal insulation properties than Bulgarian joinery, for example.

Another important indicator is water resistance and wind resistance. Here too, KöMMERLING’s results are better. This is of great importance, because it depends on this indicator whether and how much our windows will withstand rain and strong wind. When our home is on the higher floors, this resistence is extremely important. That is why it is good to invest in better quality joinery, which will provide you with greater security.

The very structure (geometry) of the German joinery is precisely calculated and made to withstand a greater load. In addition, the drainage and ventilation of the joinery also depend on the geometry.

The seals for German joinery are made of such material that there is almost no significant difference between winter and summer. You know that in winter, due to the low temperatures, most of the seals become harder and the windows are harder to close. German systems use a material that is not affected by temperature differences.

The Joinery and Facades Agency has certificates and references issued by the German Profine Group, which entitles us to manufacture KöMMERLING joinery. In order to obtain the right to produce German joinery, each company goes through a thorough study and evaluation.

In addition, Profine Group provides technical assistance to companies that have earned their trust. In special cases, we receive from them help and technical justification in deciding what profile to choose in a given situation. The German specialists study the region, what are the climatic features, the requirements for the window itself and give an exact recommendation of what joinery is best to put in this case.
