nSPB WE Patina is an energy-efficient sandwich panel with a mineral wool core of reduced density with improved thermal insulation properties and external facing made of Cor-Ten steel.
Ruukki Patina gives the facade a noble appearance, and also allows you to reduce the building’s energy consumption and CO2 emissions by up to 20%. The core made of non-combustible and environmentally friendly mineral wool with a low coefficient of thermal conductivity provides excellent thermal insulation of the panel. The special configuration of the ends of the core increases tightness and provides high sound insulation, and the patented shape of the joints prevents their internal corrosion.
A unique property of sandwich panels with Cor-Ten steel cladding is the ability to independently restore small scratches due to the formation of a new patina.
By using Ruukki Patina, you can get more points in the LEED and BREEAM certification systems.
