Tested quality

Top quality doors which machining, function and stress resist also to high requirements are maeked with a test or an approval plate in the door rabbet. Only this marking together with the test certificates confirms you as a buyer that you have decided in favour of a product of highest serviceability and safety. Pay attention to this marking, only then you can trust in extensive warranties. In Europe are only few recognised institutes which subject doors to a durable function with 200.000 closing cycles and approve them in connection with an impervious to smoke and burglary protected construction method. Our doors are tested in these institutes and provided with a corresponding marking. The performances of our products - thermal insulation, safety, energy-saving - are "official". And this advantage looks still well through the design of our doors.
