We have introduced new solutions for mounting windows and doors in the mullion and transom walls of the MB-SR50N EFEKT system.

They allow applying constructions of MB-79N, MB-86N and MB-77HS systems. These connections are based on window façade frames and appropriate adaptation profiles for doors and ensure simple prefabrication and high tightness of the connection.

The water tightness of a window attached to a façade in this way is 1200 Pa, while the water tightness of single-leaf doors is 900 Pa. You will find detailed technical information about these solutions in the catalogue of the MB-SR50N EFEKT system in the authorised zone.
