Curtain walling


MXm Toggle

Mechanical Structural Glazing


The Mxm structural glazing curtain walling is a technical design enabling the creation of fully glazed facades without attaching aluminium frames to the glazing. As an alternative to SSG (Structural Sealant Glazing), which uses traditional silicone sealant, the glazing for the fixed and opening sections is attached to the aluminium frame mechanically using special aluminium supports. From the outside, only the glazing and a thin gasket is visible.
