Mullions and transoms curtain wall The mullions and transoms curtain wall consists of vertical and horizontal elements that form a structural grid.

The mullions fixing to the wall structure is performed with galvanized steel brackets, disposed to adjustment in all directions, to recover any irregularities of the wall structure. Among the junctions of the vertical mullions and the horizontal transoms are considered special expansion joints.

To the system can be applied every type of glasses and/or blind panels, mounted with appropriate spacers. In the pressor sections and in the external horizontal covers are expected holes to allow the compensation of the steam pressure and the drainage of water on the outside, and to allow the ventilation of the perimeter of the glass sheet too.

To the pressor sections are also applied EPDM gaskets that stick to the glass and guarantee watertightness.
