What it is
Curtain walling
Mullion-and-transom curtain walling with improved thermal performance, for projects with more demanding energy targets.
Role in the project
MC Passive+
MC Passive+ is a facade system; what sets it apart from MC Wall is its thermal assembly.
What to consider
Purpose and limitations
The Passive+ name does not automatically mean that the whole building is a passive house.

Key points about the system
Passive+ is simply the name of a facade variant; the energy performance of the building envelope as a whole depends on the design. The classes shown come from the manufacturer’s technical data. Whether they apply to the assembly offered is confirmed by a relevant test report.
