Horizontal line GL-SR50N pl

Solution GL-SR50N PL “Horizontal line” is the aesthetic variant of the mullion and transom façade, in which horizontal or vertical partitions are emphasised.

This is realised by using the appropriate masking (e.g. elliptical) strips to stress one direction of façade division, whereas in lines that are perpendicular to them, the glass fastening strips are eliminated. When required, the connectors that function between fillings can be used in these lines and masked with so-called weather silicone or special gasket, thus making them not visible from the outside. As in other façade versions, hinged windows can be used in the GL-SR50N PL construction without changing its appearance.

GL-SR50N PL is used for the construction of light curtain walls of a suspended and filling type, as well as roofs, skylights and other spatial structures. Its support structure is based on a modern and proven aluminium GL-SR50N mullion and transom system offering a wide range of profiles and options for selecting the profiles to harmonize the surfaces of members on the internal side of the curtain wall, thus, creating a visually attractive connection with the curtain wall and the inner structure.
