Pre-Painted GI Pre-Insulated Ducts

Pre-Painted GI Pre-Insulated Ducts HVAC System

Outdoor and semi-outdoor ventilation systems in coastal and tropical high-humidity regions continuously face harsh environmental conditions. Including salt-laden air, high relative humidity, and significant day-to-night temperature fluctuations.When contractors use conventional PIR/PUR pre-insulated duct systems in coastal outdoor or semi-exposed applications. Standard aluminum foil facings may not provide adequate protection against prolonged salt-spray exposure. Even minor […]

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. […]
