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.

 

 Typical Application Scenarios

Commercial Complexes

As a core component of the central air - conditioning system, its compact structure can reduce the ceiling space occupation by 15%, and the exposed installation design directly enhances the aesthetic value of the building. The model with a black coating is more suitable for light - sensitive areas such as cinemas and exhibition halls.

Industrial and Transportation Fields

In ship cabins and high - speed rail carriages, glass fiber ducts achieve dual control of uniform temperature distribution and vibration noise. Their anti - corrosion properties make them perform excellently in corrosive environments such as chemical and pharmaceutical workshops.

Upgrades of Public Buildings

Antibacterial ducts are used in hospital operating rooms, which, combined with laminar flow design, can meet the Class 10,000 cleanliness standard. Large - section ducts are applied in sports stadiums, achieving an air exchange rate of 20 times per hour while maintaining a background noise below 40dB.

Green Building Practices

By scoring in the material recycling item of the LEED certification system, 95% of the materials of glass fiber ducts can be recycled, helping buildings obtain green star certifications.

 

 Selection and Technological Innovation

The new double - aluminum foil composite structure increases the compressive strength to 800Pa, making it suitable for high - pressure air supply systems. The intelligent pre - installed flange system enables zero - welding at the construction site, reducing labor costs by 50%. With the popularization of BIM technology, the accuracy of three - dimensional modeling can reach the millimeter level, and the pre - fabrication error can be controlled within 2‰.

From cost - effectiveness to full - life - cycle management, glass fiber ducts are redefining the standards for building environment control. The direction of its technological iteration focuses on cutting - edge fields such as nano - coating antibacterial and phase - change energy - storage material integration, continuously promoting the industry towards a more efficient, intelligent, and sustainable development path.
