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. […]
