10mm PIR Foam Pre-insulated Duct Panel

Aluminum Duct Panel is a compact, high-performance solution tailored for bullet train HVAC systems-where space constraints, thermal stability, and durability are critical.

Typically featuring a thin closed-cell PIR (polyisocyanurate) foam core (≤10mm thick) sandwiched between lightweight aluminum facings, it balances slim profiles (ideal for tight rail car interiors) with strong thermal insulation (thermal conductivity ≈0.022 W/m·K). This minimizes heat gain/loss for conditioned air, ensuring consistent passenger comfort even at high speeds.

Lightweight (reducing rail car load) and rigid, it resists vibration (common in high-speed travel) and corrosion from humidity. With Class 0/B1 fire resistance (low smoke, self-extinguishing) and airtight joints, it meets rail safety standards. Easy to install in curved/confined spaces, it boosts HVAC efficiency while fitting the strict dimensional limits of bullet trains.
