Phenolic Duct Panel

PU PIR vs Phenolic Duct Panels

PU/PIR vs Phenolic Duct Panels: What Is the Real Difference?

Compare PU/PIR and phenolic pre-insulated duct panels for HVAC projects, including thermal performance, fire behaviour, fabrication and practical selection. PU/PIR and phenolic panels are both used to fabricate lightweight, pre-insulated HVAC ductwork. Each panel combines a rigid foam core with protective facings, so the duct enclosure and thermal insulation are created in one fabrication process. […]

Why Phenolic Duct Panels Are Preferred for Metro Ventilation Systems

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. […]
