The Poliedra-Sky system is part of the evolutionary process of METRA building systems, enabling the design and fabrication of curtain walls or aluminum frameworks (in combination with glass, stone, and composite materials) of different shapes and dimensions, offering a wide range of functional and aesthetical solutions.
The system rightly owes its name to the "polyhedral nature" of its constructive and application possibilities.
Thanks to its aesthetics, tightness and energy-saving features, the Poliedra-Sky system can be employed in both, new buildings and in renovation, replacing or integrating new volumes.
Volcano systems was studied and designed by ALCEO France using the latest technology for manufacturing operation. This system is in conformance with French European standards
