That Krebbers has all important certifications is a side effect of our pursuit of quality.
It goes without saying that this includes the RAL quality mark for products, production and assembly as wel as the CEsymbol for all our wood and metal-wood windows. We regulary meet all ISO 9001 quality criteria and have all the necessary test certifications regarding burgarly and bullet as well as fire and smoke protection.
Satisfying current standards is not our sole objective; we also want to establish new standards. We achieve this through constant research and development, for instance in cooperation with the Institute of Window Technology IFT in Rosenheim.
Krebbers quality standards of today are going to be the standards of tomorrow.
