COR 4600 system is a lift slide door system with excellent thermal transmittance value (Uw), starting at 0.9 (W/m²K). Maximum energy efficiency is achieved by the polyamide thermal barrier 35 and 24mm wide, reticular PE profiles and high glazing capacity, allowing for up to 55mm thick glass. As an option it can be fitted with double or triple chamber glass for best thermal and acoustic insulation.

Also the system allows the use of large wings making it appropriate for closing large light wells with guaranteed thermal and acoustic insulation.

The sliding system uses wings with machinery that allows lifting while opening and descent while closing, with the closed door resting on the lower longitudinal and lateral sealing gaskets, thus increasing seal capability and acoustic insulation. Efficient and durable construction using components that prevent excessive wear. Modern, straight esthetics.

COR 4600 has 2 options for visibility in the central node: 110mm standard and 50mm minimalist.
