PIR PID Panel
PIR PID Panel serve as high-performance integrated solutions tailored for contemporary heating, ventilation and air conditioning (HVAC) systems.
Adopting a precisely engineered sandwich composite structure, these panels consist of a high-density PIR foam core renowned for superior thermal insulation performance, laminated between two anti-corrosion aluminum foil facings.
Manufactured as prefabricated units in factory conditions, each panel integrates thermal insulation, mechanical structural rigidity and airtight sealing functionality within one single component. It removes the extra step of on-site separate insulation wrapping, greatly simplifying and accelerating duct installation projects across all types of building applications.

Fire Resistance and Moisture Resistance of PIR PID Panel
Fire Resistance Class: Euroclass B-s2,d0 (for some models C-s2,d0), non-flammable, low smoke, no dripping.
Combustion Characteristics: When exposed to fire, it chars but does not melt, the smoke is low in toxicity, and complies with EN 13501-1 and HVAC duct safety standards.
Application Safety: Suitable for densely populated places such as shopping malls, hospitals, and office buildings, and has passed FM and CE certifications.
Moisture Resistance and Durability
Absorption rate: ≤ 1% (long-term immersion), double-layer barrier of closed-cell + aluminum foil, completely vapor-proof (aluminum foil > 50 μm), eliminating condensation water and mold.
Corrosion resistance: Aluminum foil is resistant to oxidation and acid-base, PIR core is resistant to aging, with a service life of ≥ 20 years, maintenance-free, twice as long as traditional ducts in terms of lifespan.
Antibacterial: Smooth surface for easy cleaning, inhibits bacterial growth, suitable for scenarios with high hygiene requirements such as clean rooms and food factories.
Why choose PIR PID Panel?
01.
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%.
02.
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.
