Advantages of Installing Pre-Insulated Duct Panels Above Ceiling

Pourquoi les panneaux de conduits phénoliques sont-ils privilégiés pour les systèmes de ventilation métropolitains ?

In metro and rail transit projects, ventilation and smoke exhaust systems are critical for safety and efficiency. In enclosed underground environments, fire and smoke spread rapidly, requiring high-performance HVAC duct solutions. As a result, GFI phenolic duct panels are increasingly preferred for their superior fire resistance, airtightness, and reliability in modern metro ventilation systems. 1. […]
