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 […]
