◆Core Advantages and Characteristics of PU Air Duct Board
(1). Extremely low thermal conductivity: The thermal conductivity of PU foam is typically between 0.022 and 0.028 W/(m·K), and it is thinner in thickness. It has a better heat preservation effect.
(2). Eliminate heat and cold loss: Effectively prevent heat exchange between air ducts and the external environment during the transportation of cold/hot air, significantly reduce the energy consumption of air conditioning systems, lower operating costs, and help buildings meet energy-saving standards.
(3). Eliminating condensation risk: The excellent insulation performance combined with the aluminum foil vapor barrier effectively prevents condensation water from forming on the outer wall of the air duct when transporting low-temperature air, avoiding mold growth and corrosion, and protecting the building structure.
Lightweight and high strength, convenient for construction of PU Air Duct Board
(1). Lightweight: Compared with the traditional combination of iron sheet air ducts and external insulation, the weight of PU air duct plates is significantly reduced (usually by more than 60%), greatly lowering the labor intensity and cost of transportation and installation.
(2). Easy to process: The plates can be cut and slotted with special tools (such as hook knives), and the operation is simple and fast.
(3). High-efficiency molding: The unique plug-in design (male and female ports or flange ports) combined with special glue (polyurethane glue) for bonding enables quick installation, excellent sealing performance, and significantly shortens the construction period. On-site production is flexible and can adapt to complex Spaces.
Outstanding structural performance and durability of PU Air Duct Board
(1). Self-supporting structure: The PU core material has a certain rigidity. After being compounded with aluminum foil, the formed board has high self-strength. The air ducts made from it can meet the conventional pressure requirements without additional reinforcement, simplifying the structure.
(2). No cold bridge: The overall insulation structure completely eliminates the possibility of "cold Bridges" formed by metal connecting parts, etc., ensuring the continuity of insulation effect.
(3). Corrosion-resistant and long service life: The aluminum foil surface layer effectively resist corrosion from damp air, weak acids, weak alkalis, etc. The internal PU core material is stable, and the overall service life is long (usually up to more than 20 years), with low maintenance costs.
