Ruukki acoustic cladding 50 mm

All Ruukki design and low profiles with 30% continuous perforation and suitable background insulation layer of 50 mm removes ﬂutter echoes between vertical parallel surfaces and improves absorption properties of both wall and ceiling surfaces.

This solution is optionally available with following sustainable features:

Steel facings made of recycled steel (SSAB Zero) for significantly lower CO₂ emissions and high circularity (Ruukki LowCarbon)
