PIP Insulation Duct Panel
PIP Insulation Duct Panel is a sandwich composite board with double-sided aluminum foil and closed-cell PIR foam core. It integrates ventilation and thermal insulation, λ≤0.022W/(m・K), B1 fire grade, 70% lighter than iron ducts. No on-site secondary insulation, widely used in commercial HVAC, clean rooms and public buildings to cut energy loss by 20%-30%.

Product Structure and Material Properties of PIP Insulation Duct Panel
PIP stands for Pre-Insulated Panel, which is a standard three-layer sandwich structure: double-sided embossed aluminum foil surface layer + high-density PIR closed-cell foam core material. The standard size is 3950×1200mm, with thicknesses of 10/20/25/30/40mm and core material density of 50kg/m³.
Core measured performance data: thermal conductivity ranges from 0.018 to 0.022W/(m・K), significantly superior to traditional glass wool at 0.035W/(m・K) and rock wool at 0.038W/(m・K); 28-day water absorption rate ≤ 1.5%, the closed-cell structure prevents water vapor penetration, with waterproof grade IP65. Long-term use has no condensation dripping problem. Compressive strength is 0.25MPa, wind pressure tolerance is ≥ 1500Pa, meeting the large ventilation capacity requirements for shopping malls and hospitals; working temperature range is -192℃ to 120℃, both cold and hot air ducts can be adapted, without defects such as high-temperature deformation or low-temperature cracking. The aluminum foil surface layer is resistant to acid, alkali, and salt fog, and the outdoor basement usage has an aging life of ≥ 10 years, without rust or corrosion risks.
Construction Installation and Labor of PIP Insulation Duct Panel
The traditional iron sheet ducting involves four processes: cutting, bending, welding, and on-site insulation wrapping. For a 100㎡ duct, it requires 6 workers to complete the construction in 3 days. With PIP materials, only three steps are needed: cutting, edge folding, and sealing. For the same engineering volume, 3 workers can complete it in 1.8 days, reducing the overall construction period by 40% and lowering labor costs by 45%.
No need to carry auxiliary materials such as insulation cotton and binding straps, there is no dust pollution at the site, meeting the clean construction requirements of hospitals and food workshops. Each single sheet weighs only 12kg, and one person can handle it, making the high-altitude ceiling operation safer. The dedicated aluminum foil sealing tape and flange accessories are provided as a package. The duct's air tightness reaches the D-level standard, with the leakage volume being only 1/4 of that of the iron sheet ducting. There is no need for frequent leak repair and maintenance in the later stage, and the maintenance cost throughout the entire life cycle is reduced by 60%.
Fire Safety and Environmental Health of PIP Insulation Duct Panel
The core material PIR foam meets the national standard B1 level for flame retardancy, with an oxygen index of ≥32. When burning, it forms a dense carbonized layer to prevent the spread of flames, with a smoke density level of s2. It does not cause molten droplets to ignite surrounding building materials, and complies with fire safety regulations for shopping malls, hospitals, and office buildings.
Compared to PU foam B2 level combustible and phenolic board brittle and prone to powdering, PIP combines fire resistance with structural strength. Environmental testing data: No formaldehyde release, VOC organic volatile substances ≤ 6g/kg, no soluble heavy metals such as lead and cadmium, and has passed SGS clean material certification, suitable for scenarios requiring high air cleanliness such as operating rooms, laboratories, and school classrooms. The foam does not contain CFC, HCFC fluorocarbon blowing agents, with an ozone depletion coefficient of 0, meeting domestic dual-carbon and EU environmental standards, and can be given bonus points in green building evaluation.
