Pre-insulated PIR Air Duct Board
Pre-insulated PIR Air Duct Board is a core high‑performance component for modern HVAC systems.
Featuring an integrated sandwich structure of aluminum foil facings bonded to a rigid PIR foam core, it serves as a superior replacement for conventional galvanized steel ducts with field‑applied insulation.
Widely trusted across diverse building applications, it is extensively used in hotels, office buildings, airports, hospitals and other commercial and public facilities.

Will Pre-insulated PIR Air Duct Board crack or deform after long-term use?
Proper installation is critical to ensuring the Pre-insulated PIR Air Duct Board remains free of cracking, warping, or deformation throughout its service life. We utilize specially formulated, high-strength matched adhesive that delivers exceptional bonding performance between duct panels, joints, and connections. This robust adhesive ensures a durable, seamless bond that resists separation even under varying temperature and humidity conditions.
In addition, strict adherence to standard hanger spacing and proper reservation of expansion gaps effectively mitigates structural stress caused by thermal expansion and contraction during operation. These installation measures prevent undue tension, bending, or joint failure, eliminating potential structural damage over time.
As a result, the Pre-insulated PIR Air Duct Board maintains outstanding structural stability, consistent dimensional integrity, and reliable performance during long-term continuous operation.
