Double Aluminum-Faced Pre-Insulated PIR Duct Board

DATELINE: [China], [8/13, 2026] — [kinmar company ], a manufacturer specializing in ventilation and fire smoke exhaust ducting materials, today announced the launch of its double aluminum-faced polyurethane (PIR) insulated duct board, an integrated duct-and-insulation solution designed for central air conditioning, ventilation and smoke exhaust systems.

PRODUCT OVERVIEW

The double aluminum-faced PU duct board features a rigid, closed-cell polyurethane foam core permanently bonded between two aluminum foil facings through a continuous lamination process. The factory-bonded structure combines the air duct and thermal insulation into a single component, eliminating the need for separate on-site insulation work.

KEY FEATURES & BENEFITS

• Superior thermal insulation: the closed-cell polyurethane core delivers a low thermal conductivity of approximately [0.022–0.028 W/m·K], helping reduce energy loss and operating costs of HVAC systems.
• Light weight, high rigidity: the board is lightweight yet dimensionally stable, reducing structural load and enabling faster, easier handling and installation on site.
• Integrated insulation: insulation is factory-bonded into the panel, eliminating conventional lagging works, shortening construction time and lowering labor costs.
• Smooth, durable surfaces: aluminum foil facings provide a clean, corrosion-resistant surface that is easy to maintain and compatible with standard duct fabrication (cutting, folding, flange connection).
• Sound attenuation: the foam core contributes to noise reduction and improved indoor acoustic comfort.
• Fire performance: the flame-retardant core is rated [insert fire rating, e.g., Class B1 to GB 8624 / Euroclass [B-s1,d0] to EN 13501-1], meeting the requirements for [ventilation / fire smoke exhaust] applications as specified.
• Environmental profile: manufactured with [HCFC-free / low-GWP] blowing agents [confirm], supporting green building initiatives.

TYPICAL APPLICATIONS

• Central air conditioning and ventilation ductwork in commercial, industrial and public buildings
• Fire smoke exhaust duct systems requiring [fire-resistant specifications]
• HVAC systems for clean rooms and dust-controlled environments
• Low-temperature air supply and [cold room] ventilation systems
  
• Renovation and retrofit projects where space and installation time are critical
