Key Application Areas of Fiberglass Felt

As a versatile insulation material, Fiberglass felt plays a critical role across numerous industries. In the construction sector, it is frequently used as wall cavity insulation installed within light steel stud partitions, effectively enhancing the thermal performance of buildings. It is also laid above suspended ceilings or beneath corrugated steel roofing to block heat ingress in summer and prevent indoor heat loss in winter. When installed between floor layers, Fiberglass felt reduces footstep noise and sound transmission, improving living comfort.

In HVAC systems, Fiberglass felt is widely applied. It can be adhered to the inner walls of air ducts, providing both thermal insulation and sound absorption. Wrapped around ventilation pipes, it minimizes energy loss, and when applied to the surfaces of air handling units and fan coil units, it helps maintain operational efficiency. The industrial sector also demonstrates strong demand for Fiberglass felt, whether as furnace lining material, insulation for steam and thermal oil pipelines, or as a covering for large storage tanks to stabilize medium temperatures.

The transportation industry similarly relies on Fiberglass felt. It is commonly installed beneath car doors, engine hoods, and floor mats to absorb road noise. In shipbuilding, it is used in cabin bulkheads and ceilings, offering both thermal insulation and fire resistance. When fill in train carriage wall cavities, it significantly enhances passenger comfort. In home appliance manufacturing, Fiberglass felt placed inside oven housings prevents heat leakage; wrapped around water heater tanks, it reduces standby heat loss; and as insulation within dishwasher door panels, it improves overall energy efficiency ratings. Additionally, Fiberglass felt finds applications in agriculture-covering greenhouse walls or roofs reduces nighttime heat loss, while laying it over seedling beds in winter provides frost protection.
