Our Modulusz systems carry CE marking, and almost all our products are sound-tested in an accredited laboratory, so architects can specify them with confidence and clients can rely on them.
Our newest systems, pivot, bi-fold and Secreto, are next in line for testing.
Read the sound testEven our basic models carry premium German hardware. Most of our clients then make the door their own.
We design the system, engineer every part and build every door ourselves, in our own workshop in Győr, between Vienna and Budapest.
I specified XS-ALU products in two of my interior design projects. The collaboration was extremely smooth from the design phase onwards: helpful, fast and professional throughout.
CAD/DWG details, data sheets and sound test reports for your drawings, plus engineering support when a project needs something new.
