In the modern construction and industrial fields, glass fiber ducts have gradually become the preferred solution for HVAC systems due to their innovative material properties and multi - functional design. This type of duct, which is based on ultra - fine fiberboards and compounded through special processes, not only breaks through the limitations of traditional materials but also achieves a comprehensive upgrade in energy conservation, safety, and efficient construction through multiple performance advantages.
Core Performance Advantages
1. Efficient Insulation and Energy Saving
The glass fiber duct uses a multi - layer composite structure. The density of the ultra - fine centrifugal glass wool in the middle layer reaches 70 - 75kg/m³, and the thermal conductivity is as low as 0.032W/(m·K), which can reduce heat loss by more than 30%. Its airtightness is 40% higher than that of traditional ducts, and the air leakage rate is less than 2%, significantly reducing the operating energy consumption of the air - conditioning system.
2. Excellent Noise Reduction and Acoustic Optimization
The porous fiber structure can absorb mid - and high - frequency sound waves. Combined with the inner anti - bacterial glass fiber cloth, the duct can maintain an operating noise below 35dB even at a wind speed of 20m/s, making it particularly suitable for acoustically sensitive places such as theaters and recording studios.
3. Multiple Protections and Safety Assurance
It has passed the Class A fire - protection certification, with a fire resistance limit of more than 2 hours; the water repellency rate exceeds 98%, enabling it to handle environments with a humidity of less than 86%. The inner anti - bacterial coating effectively inhibits the growth of mold, meeting the requirements of clean spaces such as medical and food industries.
4. Lightweight Design and Construction Innovation
The unit weight is only 1/3 of that of traditional galvanized iron sheet ducts. Combined with modular connection technology, the construction efficiency is increased by more than 50%. The 6 - meter standard pipe section can reduce on - site joints by 80%, reducing the risk of air leakage.
5. Environmental Protection and Long - term Economy
It does not contain harmful substances such as formaldehyde and benzene, and the fiber scattering rate meets the ISO standards after testing. The service life exceeds 25 years, saving 30% of the initial investment and 60% of the maintenance cost compared with traditional ducts.
