Interior Perforated Sheets
Combining aesthetic grandeur with high technical capability, our Interior Perforated Sheets are designed to control acoustics while elevating interior design. Engineered with high sound absorption coefficients (NRC) for acoustic grades, these panels mitigate reverberation in modern spaces. They are offered with custom perforation geometries and premium finishes including anodizing, PVDF, and electrostatic powder coatings.
Key Features
High sound absorption coefficients (NRC) for acoustic grades
Bespoke architectural styling with customizable geometric patterns
Finished with electrostatic powder coatings and PVDF finishes
ISO 9001:2015 certified lightweight handling and framing options
Common Applications
