Curtain walls

Contemporary taste and great technology made available for architects and designers by METRA Building. Our Poliedra-Sky aluminium integrated curtain wall systems are designed to enhance the most ambitious architectural contexts at an aesthetic and structural level, freeing designers from structural constraints and offering them the possibility to make their design visions unique.

METRA Building curtain walls are a system capable of creating increasingly complex geometrical shapes in combination with glass, LAMINAM® ceramic, stone, wood and composites guaranteeing incredible durability, thermal insulation, soundproofing power, water tightness, resistance to air, salt and aggressive atmospheric agents.

The advantages are completed by energy saving, integrability with photovoltaic systems and high-quality opening-closing devices.

Performance, emotion and visions of the future with the Poliedra-Sky product range by METRA Building.

The ideal applications of curtain walls in residential construction are large glazing for verandas, winter gardens, stairwells and skylights in which they ensure a significant increase in brightness, use of sunlight and energy saving.
