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)
Structure
- Ruukki design profile or low profile with 30 % perforation
- Acoustic fabric
- Hat profile 0,6 mm; h = 50 mm, w = 70 mm
- Low density rock wool ~ 25 kg/m³, not in Ruukki delivery
- Base structure: Ruukki sandwich panel (SPA150E) / all kind of base structure
