Polyurethane Pre-insulated Duct Panels

Polyurethane Pre-insulated Duct panels deliver outstanding anti-condensation performance by virtue of high-grade thermal insulation and fully airtight aluminium foil facings. PIR cellular foam boasts an ultra-low thermal conductivity coefficient, which equalizes the temperature of duct outer surfaces and internal airflow. This greatly reduces the temperature differential between ductwork and ambient atmosphere, preventing surface temperatures from reaching the dew point, the fundamental factor leading to surface condensation.

In addition, continuous sealed aluminium foil linings obstruct lateral moisture migration from the surrounding environment, while precision-machined joint structures eliminate air infiltration and exfiltration. This isolates humid ambient air from the low-temperature insulating core, further mitigating condensation formation.

Suppressed condensation eliminates moisture retention and mould colonisation, and prevents progressive degradation of insulation thermal performance over operational years. Constant thermal resistance of the duct assembly avoids elevated heat transfer losses induced by dampened or compromised insulation. Consequently, the associated HVAC installation maintains steady low energy draw, sustaining consistent energy efficiency across the full design service life of the duct system.
