Material Structure and Physical Properties of Palduct Foam Panel
The Palduct Foam Panel is an integrated pre-insulated air duct board made of double-sided aluminum foil and closed-cell foam core material. The mainstream core materials are divided into PIR and PU types, and the overall design adopts a fiber-free structure.
The measured thermal conductivity is stable at 0.018 - 0.022 W/(m·K), which is much lower than the average value of 0.032 W/(m·K) of traditional rubber and plastic insulation boards. The insulation advantage is prominent.
The volume water absorption rate of the panel is ≤ 3%, and the closed-cell structure blocks water vapor penetration. The dimensional change rate under alternating temperature and humidity conditions is ≤ 3%, and it will not affect the sealing performance of the air duct due to moisture absorption.
The overall density of the product is controlled at 40 - 55 kg/m³, which is more than 60% lighter than the galvanized iron sheet air duct of the same specification. It has a small self-weight and is suitable for ceiling and pipeline laying in high-rise buildings and light steel structure buildings.
Energy Saving and Cost Reduction of Palduct Foam Panel
This type of board is the core material for energy-saving renovations of the HVAC system. Its integrated structure eliminates the multi-layer construction of traditional iron sheet ducts along with insulation and protective layers.
Actual engineering data shows that using this board can reduce the overall energy consumption of the central air conditioning and ventilation systems by 20% to 35%.
On one hand, the ultra-low thermal conductivity significantly reduces the heat loss in the ducts, and the insulation performance does not decline by more than 2% over a long period of use, unlike the problem with ordinary insulation materials where the performance drops significantly within 3 to 5 years. On the other hand, the inner wall of the duct is smooth, resulting in a low wind resistance coefficient, and the operating load of the fan decreases accordingly.
Construction Efficiency and Space Adaptation of Palduct Foam Panel
The integrated pre-manufacturing feature is one of the core advantages of this product. The longest single sheet can reach 4 meters. After standardized cutting in the factory, only splicing and sealing are required on-site. Compared with the traditional "sheet metal + external insulation" process, the construction time on-site is shortened by more than 40%, and the labor cost is also reduced simultaneously.
The overall thickness of the sheet is thin, and the width of the connection components is basically the same as that of the duct body. Compared with the traditional ducts, it can save 15% to 20% of the ceiling installation space, perfectly adapting to densely piped areas such as shopping malls, office buildings, and underground garages.
At the same time, special connection pieces and sealing accessories are provided. The tightness rate of the ducts reaches nearly 100%, reducing air leakage problems. Comprehensive calculation shows that under the same engineering volume, the comprehensive cost of this sheet material is approximately 10% lower than the traditional solution.
