Fire-Resistant Interior Design with Perforated Acoustic Metal Mesh and Powder-Coated Finish

In high-risk environments like transport hubs, hospitals, laboratories, and public gathering spaces, interior systems must go beyond aesthetics. Fire-resistant perforated acoustic metal mesh panels, particularly those with durable powder-coated finishes, provide a high-performance solution for architectural safety, sound control, and design integration. These systems are engineered to meet rigorous international safety standards while delivering functional and aesthetic flexibility.

📌 Case Study 1: Copenhagen Metro Terminal Extension

Client: Greater Copenhagen Transit Authority | Location: Central platform halls and escalator shafts (860 m²)

To comply with stringent EU fire regulations, the terminal incorporated Class A1 fire-rated stainless steel perforated mesh panels (1.8mm thick), powder-coated with zero-VOC matte grey finish. The panels were designed to resist flame spread and retain structural integrity up to 750°C, meeting EN 13501-1:2018.

Installation: Panels were installed with floating anchors and thermal-break insulation layers behind perforated metal for dual acoustic + thermal safety. Acoustic core used mineral wool, achieving NRC 0.85 (ISO 354 certified).

Performance: Flame resistance verified via ASTM E119, retaining >90% structure after 2h test. Passenger soundscape feedback improved by 32% based on acoustic consultant survey.

📌 Case Study 2: Biomedical Research Lab, Zurich

Client: Swiss Molecular Science Institute | Use: Corridor walls and suspended acoustic ceilings

Given strict flammability regulations and clean-room compatibility, architects specified aluminium perforated mesh with ceramic-polymer hybrid powder-coat. Hole design: Ø1.5mm, 45% open area. Backed with ceramic fire blankets for extended protection.

Outcome: Achieved ISO 1182 (non-combustibility) and ISO 5660 compliance. Post-occupancy evaluations highlighted 40% improvement in noise masking within hallways.
