Front wall installation system: Installation of windows, doors, or other facade elements in the insulation layer allows for very good isothermal processes and thereby optimal thermal insulation values for energy-saving building projects.

The IFT-tested adhesion of the frame to the masonry results in an innovative load transfer that enables this installation system to mount heavy elements even onto lesser subsurfaces. At the same time, the adhesive serves to seal the frame to the masonry. Screws are only used for added security or subsurfaces not suitable for the adhesive.

By using a circumferentially solid frame, significantly better sound insulation values are achieved compared to simple consoles or corner solutions made out of plastic.

Potential sources for leaks are greatly reduced through a defined installation opening.

Installation time is substantially reduced.
