These are systems in which all the elements that make up the facade system are assembled and installed on the construction site.
In contrast to panel facade systems, classical facades have less manufacturing workmanship, but much more installation workmanship.
Vertical carrier (mullion) profiles and horizontal carrier (transom) profiles form a carrier aluminum carcass that will form the facade plane with anchors that allow 3-dimensional adjustment.Then, the inside of the existing aluminum carcass is glazed and the assembly is completed.
On classic clamshell facades, glass is fixed with aluminum carcass printing and cover profiles. For this reason, these cover profiles are seen when viewed from the outside around the glass plane.
