PIR PID Board
PIR PID Board deliver high-performance, environmentally sustainable air distribution for modern HVAC systems. Constructed as an integrated sandwich panel with aluminum foil facings and rigid PIR foam core, they outperform traditional galvanized steel ducts requiring on-site insulation. Featuring low energy loss and eco-friendly formulation, they support energy conservation and meet green building requirements. Ideal for hotels, office complexes, airports, hospitals and other commercial and public buildings.
Composition & Structural Design
This panel features a sandwich composite structure, consisting of an insulating foam core sandwiched between two robust protective facing layers:
Insulating Core Substrate The core adopts rigid PIR foam with high closed-cell structure. It delivers outstanding thermal insulation and superior moisture resistance. Moreover, the foam is manufactured without ozone-depleting CFCs and HCFCs, meeting eco-friendly production standards.
Dual-Side Protective Facings Both sides of the foam core are firmly laminated with protective claddings, most commonly embossed aluminum foil. The standard indoor-grade aluminum foil thickness is 80 microns. For outdoor installation and heavy-duty service requiring enhanced durability, thicker aluminum foil or pre-coated galvanized steel panels are available as alternatives.

Material and Structural Characteristics of PIR PID Board

Advantages of the core insulation layer: It adopts polyisocyanate (PIR/PU) foam base material, with a thermal conductivity as low as 0.018-0.022 W/(m · K). Its insulation and heat insulation performance far exceeds that of traditional rock wool and glass wool. It can effectively prevent the heat exchange between the cold/hot air inside the air duct and the external environment, reduce energy loss, and lower the energy consumption of the air conditioning system operation.
Composite structure design: It adopts an integrated structure of "insulation layer + outer protective shell". The outer protective shell can be made of materials such as aluminum foil, color steel plate, and PVC, which has excellent moisture-proof, anti-corrosion and anti-aging performance. It can prevent the insulation layer from absorbing moisture and failing, and extend the service life of the product. The inner layer is closely attached to the air duct, reducing air gaps and enhancing insulation and sealing performance.
Stable physical properties: The product has a uniform density (50-55 kg/m³), a compressive strength of ≥250 kPa, is not prone to deformation or collapse, and can withstand minor collisions during installation and use. It also has excellent flame-retardant performance (reaching B1 grade flame-retardant standard), and has low smoke toxicity when exposed to fire, ensuring safe use.
