Together with the PfB Prüfzentrum für Bauelemente, we have subjected our aluminum folding door 46 AF to a test with regard to heat transfer coefficient ("U-value"). The result: Our folding door achieves a very good value of up to 2.4 W/m²K in the usual design.

We have thus created further facts as to why our product is outstanding. In addition to functional performance, top quality and a fair price, we have now also officially confirmed the thermal performance of our folding door. This result opens up completely new possibilities for our customers, e.g. in the context of public tenders or specifications of large construction projects, where U-values already play a very important role today.
