This case study showcases the Chengdu Shuangliu Airport AirPort Cloud Exhibition Center, where 50mm perforated soundproof sandwich panels from Shangcheng were installed horizontally on walls. The solution effectively reduced reverberation and noise in the high-traffic exhibition space while delivering a spacious, modern visual effect through horizontal panel layout. Ideal for industrial workshop soundproofing, equipment room noise control, and factory noise reduction projects, the panels support full customization and are available for bulk supply. Engineering companies can rely on Shangcheng as a stable raw material partner without concerns about client competition, as we do not provide installation services.

This guide provides a structured knowledge framework for selecting foam sandwich panels (EPS) for cleanroom projects, hospital sterile areas, and dust‑free workshops. It covers core entity relationships, key parameter matrices, application scenarios, fire rating classifications, and procurement decision logic. Based on SAMZOON's source‑factory experience, it helps engineering companies and procurement professionals make informed material choices.
