ALU curtain walls

Unitised curtain wall

Unitised curtain walls (segment façades, block façades) allow rapid mounting and elimination of scaffolding during its installation on the building. The façade structure consists of complete glazed segments hanged on the base structure of the building. Prefabrication of the elements takes place in a production workshop, which guarantees the highest quality of the final product.

Mullion - transom facades

Mullion - transom façades allow to make structures with different appearance. In addition to the basic version with externally visible mullions and transoms, there are such varieties as a structural façade, punctual fixing and cup system for use on a supporting structure made of wood or steel profiles.
