The ST FLEX Green sliding door illustrates dormakaba’s commitment to increasing energy efficiency and thus to improving the sustainability of buildings. Despite its slender profile design, the ST FLEX Green comes with outstanding thermal insulation, as confirmed by the German testing, surveillance and certification body “ift Rosenheim”.
German EnEV 2009
Even the smallest ST FLEX Green door system meets the requirements of the Germany’s regulation EnEV 2009, which stipulates a certain UD value (thermal transmission co-efficient) for complete door systems.
Reduced CO2 emissions
As a highly energy efficient solution, the ST FLEX Green sustainabilty reduces day-to-day energy and heating costs and cuts C02 emissions.
Complies with latest German energy-saving regulations
ST Flex Green satisfies the requirements of the latest German energy-saving regulation (EnEV 2009) while also harmonizing perfectly with the existing dormakaba sliding door range.
Extremely solid construction
Despite its slender profile system with thermal insulation, the ST FLEX GREEN is of extremely solid construction.
