In modern building HVAC systems, ventilation ducts not only perform air transport but also significantly impact building energy consumption. Fiberglass ducts, as a ventilation material integrating insulation, sound absorption, and air supply, are widely used in commercial buildings, industrial plants, and public facilities projects due to their lightweight, easy installation, and significant energy-saving effects. Through analysis of actual engineering cases, we can gain a clearer understanding of the advantages and value of fiberglass ducts in different scenarios.

In large commercial complex projects, the air conditioning system is massive. Traditional galvanized iron ducts typically require an external insulation layer, resulting in complex construction procedures and significant space requirements. Using fiberglass ducts allows for an integrated duct and insulation structure, reducing construction steps and improving installation efficiency. Simultaneously, fiberglass itself has excellent sound absorption properties, reducing fan noise and enhancing the comfort of commercial spaces. In some shopping mall projects, the use of fiberglass ducts has significantly shortened the overall construction period and effectively controlled system energy consumption.

In hospital building projects, high requirements exist for air quality and noise control. The internal surface of fiberglass ducts can be treated with antibacterial materials to meet the hygiene requirements of medical environments. Furthermore, their excellent sound-absorbing properties reduce equipment operating noise and improve the ward environment. In addition, the lightweight nature of fiberglass ducts helps reduce the structural load on buildings, making them particularly suitable for multi-story or renovation projects. Therefore, they have a strong competitive advantage in hospital HVAC system engineering.

In industrial plant projects, especially in places with high requirements for air cleanliness such as electronics manufacturing and food processing, fiberglass ducts also demonstrate good applicability. Their stable thermal insulation performance effectively reduces cooling loss and improves the operating efficiency of air conditioning systems. At the same time, modular production facilitates rapid on-site installation, reducing labor costs and accelerating construction progress. These project examples show that fiberglass ducts not only meet technical requirements but also have significant economic advantages.

In the field of public buildings, such as airport terminals, stadiums, and convention centers—large-space buildings—duct systems are long and large-scale, requiring high material weight and construction efficiency. The lightweight nature of fiberglass ducts reduces the difficulty of hoisting and the number of supports, thereby reducing the overall project cost. Furthermore, its excellent thermal insulation properties reduce heat loss, contributing to the achievement of building energy conservation goals.

Analysis of multiple engineering cases reveals that the main advantages of fiberglass ducts lie in their high construction efficiency, stable thermal insulation performance, good noise reduction, and low system operating energy consumption. Compared to traditional metal ducts, their overall energy-saving effect is more significant, making them particularly suitable for the needs of modern green and energy-efficient building projects.

Overall, as building energy conservation standards continue to rise and construction efficiency requirements increase, the application prospects of fiberglass ducts in HVAC engineering will continue to expand. For projects seeking energy conservation, noise reduction, and optimized construction efficiency, fiberglass ducts represent a ventilation solution with high application value.
