PID Foam Duct Board
UNT PIR Pre-insulated Duct Panel consist of 20mm thickness closed cell PIR insulation foam and 60 micron thickness aluminum foil.
UNT Aluminum foil is embossed on both sides and coated with a 2g/㎡ layer of corrosion-resistant epoxy varnish paint.
UNT PIR Air Duct Panel has a high performance insulating material with excellent thermal resistance and fire resistance. This kind of material has a wide range of applications in HVAC (Heating, Ventilation and Air Conditioning Duct) systems. It is a kind of fireproof duct board.
UNT can also manufacture other thickness of PID duct panel, such as 10mm, 15mm, 20mm, 25mm, 30mm, 40mm etc. Aluminum foil can also be available in other thickness.
Key Components of PID Foam Duct Board
2.1 Polyurethane Foam Core
The 20mm thick polyurethane foam core is the heart of this duct board. Polyurethane is renowned for its superior thermal insulation. It has a very low thermal conductivity, which means it can effectively prevent heat transfer.
This property is crucial in maintaining the desired temperature inside the ducts, whether it is for heating or cooling systems.
2.2 Aluminum Foil Facings
The duct board is faced with 60/80 micron aluminum foil on both sides. The aluminum foil serves multiple important functions.
Firstly, it acts as a vapor barrier, preventing moisture from entering the polyurethane foam core. Moisture can degrade the insulation performance and lead to mold and mildew growth, which is not only a health hazard but also reduces the lifespan of the duct system.
Secondly, the aluminum foil has a reflective surface that can enhance the thermal insulation performance by reflecting radiant heat. This is particularly useful in situations where the ducts are exposed to high - temperature environments, such as in attics or near industrial equipment.
Features and Benefits of PID Foam Duct Board
3.1 Energy Efficiency
The combination of the low - thermal - conductivity polyurethane foam and the reflective aluminum foil results in excellent energy efficiency. By minimizing heat loss or gain, the duct board helps to reduce the energy consumption of heating, ventilation, and air - conditioning (HVAC) systems. This, in turn, leads to lower energy bills for building owners and operators. In an era where energy conservation is of utmost importance, this feature makes our duct board a sustainable choice.
3.2 Durability
The aluminum foil facings protect the polyurethane foam from physical damage, such as scratches and impacts. The foil is also resistant to chemicals and UV radiation, ensuring that the duct board maintains its performance over a long period of time. The durable construction of the duct board makes it suitable for both indoor and outdoor applications, even in harsh environmental conditions.
3.3 Easy Installation
The duct board is lightweight and easy to cut and shape, which simplifies the installation process. It can be fabricated into various duct shapes and sizes using standard woodworking tools, reducing the time and labor required for installation. Additionally, the smooth surface of the aluminum foil makes it easy to seal the joints and connections, ensuring an airtight duct system, which is essential for maintaining the efficiency of the HVAC system.
3.4 Fire Resistance
The polyurethane foam used in our duct board has good fire - resistance properties. It is formulated to meet certain fire safety standards, providing an added layer of safety in case of a fire. The aluminum foil facings also do not contribute to the spread of fire, further enhancing the fire safety of the duct system.
Applications of PID Foam Duct Board
4.1 HVAC Duct Systems
The primary application of our duct board is in the construction of HVAC duct systems. It can be used for supply and return ducts in commercial buildings, such as offices, shopping malls, and hotels, as well as in residential buildings. The energy - efficient and quiet operation of the duct system made from our duct board ensures comfortable indoor environments while reducing energy costs.
4.2 Industrial Duct Systems
In industrial settings, where there may be high - temperature or corrosive environments, our duct board can be used for exhaust ducts, ventilation ducts, and process ducts. The durability and resistance to chemicals and heat of the duct board make it suitable for these challenging applications.
