Polyurethane Pre-insulated Duct Panel
It is a high-performance ventilation duct product, which is widely used in HVAC systems. The following is a detailed introduction:
Basic Structure: It is a sandwich structured panel. The core is Polyurethane (PU) foam, which is a closed-cell insulating material. The two outer layers are aluminum sheets or aluminum foils.
Panel Structure: Silver Alu. Foil/ PU Foam/ Silver Alu. Foil
Foam Density: 50kg/CBM
Panel Dimension: 3950mm*1200mm*20mm
Alu. Foil: 60 or 80 Micron (Embossed)
Fire Rating: Class 0 (BS476Part 6&7)
Performance dimension of Polyurethane Pre-insulated Duct Panel
The closed-cell rate of polyurethane foam core material is as high as over 95%, and its thermal conductivity is as low as 0.018-0.022W/(m · K), which is far superior to traditional insulation materials such as rock wool and glass wool. During the operation of the HVAC system, it can effectively prevent the heat exchange between the cold and hot air inside the air ducts and the outside. In summer, it reduces the loss of cold air, and in winter, it lowers heat loss. It has been measured that it can reduce the energy consumption of the air conditioning system by 15% to 20%.
The double-sided composite metal or aluminum foil protective layer endows the board with excellent compressive and impact resistance, enabling it to withstand external force compression during the installation and use of air ducts without easy deformation or damage.
The fire safety performance complies with the B1 grade flame retardant standard of GB 8624-2012 "Classification of Fire Performance of Building Materials and Products", and some high-end models can meet the A grade non-combustible requirement.
Cost Dimension of Polyurethane Pre-insulated Duct Panel
Although the initial procurement and installation costs per square meter are higher than those of traditional insulation materials, the panels are integrated prefabricated components and do not require on-site secondary insulation layer pasting, which can significantly shorten the construction period and reduce labor costs. Data shows that its installation efficiency is 40% higher than that of the traditional air duct insulation process, and it can reduce on-site construction costs by 30%. The overall initial investment cost performance is outstanding.
The moisture-proof and corrosion-resistant properties of the board in the later operation and maintenance cost can reduce the frequency of maintenance and replacement of the insulation layer of the air duct, and basically no large-scale maintenance is required within a 15-year service life. At the same time, its energy-saving effect can reduce the electricity cost of the air conditioning system in the long term. Taking a 10,000-square-meter commercial building as an example, it can save about 50,000 to 80,000 yuan in electricity fees each year, and the price difference of materials in the early stage can be recovered throughout the entire life cycle.
Environmental Protection of Polyurethane Pre-insulated Duct Panel
The production process is environmentally friendly by using chlorofluorocarbon-free (HCFC-free) foaming agents, which do not damage the ozone layer and meet the environmental protection requirements of the Montreal Protocol. During the production process, waste materials can be recycled and reused, with a waste recycling rate of over 80%, reducing resource waste and environmental pollution.
The environmental friendliness of the usage and recycling process: No harmful substances are released during the usage period, and the energy-saving feature can indirectly reduce carbon emissions from power plants. After the product is scrapped, the core material can be crushed and used as a building filler, and the metal protective layer can be recycled and smelted, achieving resource recycling and utilization, which is in line with the domestic "dual carbon" goals and green building certification standards.
