System Overview A Duct Cleanroom Panel is a pre-insulated board for fabricating clean HVAC air ducts — a smooth metal facing over a rigid insulation core, with a galvanized perimeter for flanged jointing, made to a ≤ 2 mm/2 m flatness tolerance. Key advantages: Built-in Insulation: The core insulates and prevents condensation — no separate lagging needed. Clean, Low-Leakage Airway: Smooth, dust-free interior with airtight, sealed joints. Light & Fast to Build: Lighter than sheet-metal duct and quick to cut, fold and assemble on site.
