Products Description
Pre-insulated PID Duct bring a series of technical, practical and economic advantages to HVAC systems. These pre-insulated duct panels integrate structural strength, insulation performance and additional functional layers (such as moisture-proof and flame-retardant layers) into a single product, which has more advantages than traditional duct methods (such as metal ducts with separate insulation layers).
Why choose pre-insulated PID air duct panels?
High air tightness and performance reliability
Air leakage is the main inefficiency problem of HVAC systems, which wastes energy and reduces indoor air quality.
Factory sealed joints: The high-quality panel design features airtight connections (such as glued edges or mechanical locks), with an extremely low air leakage rate. Studies show that the air leakage rate of prefabricated insulated air ducts can be as low as 1% to 2% of the airflow, while the air leakage rate of poorly installed metal air ducts with insulation layers can reach 5% to 10%.
Durability and long-term effectiveness
Structural integrity: The outer protective surface (such as aluminum foil, galvanized steel plate or reinforced foil) protects the insulation core material from physical damage, corrosion or pest infestation.
Environmental stress resistance: Many PID boards undergo moisture-proof treatment (such as hydrophobic foam core) and chemical stability optimization to ensure performance in humid, industrial or coastal environments.
