Light curtain wall system – MC-Wall – consisting of vertical pillars and horizontal bolts joined together using stainless steel pins. 2 or 3 Ø 6 stainless steel connections for one joint provide very good quality of pillar-bolt connection, either if confronted by the wind force or in case of glass generated pressure. Bolts are isolated by the use of a thermal insert installed by Aliplast company at the stage of profile production. Correct choice of the insert depends on the size of curtain wall panel. It is possible to use panels from 24 to 31mm in case of bolts with fused thermal insert and up to 42mm in bolts with separate thermal insert. In the place of wall mounting, pillars have a plastic isolation profile installed. Pillar construction is always traditional: it means thermal insert, mounting and masking panels are separate elements. Whole construction of the curtain wall can be finished on the inside using various kinds of decorative masking panels with round edges, so called ‘soft line’ and traditional sharp edges panels.
