In ventilation and air conditioning engineering, duct systems not only serve the function of supplying and returning air but also directly affect system energy efficiency, noise levels, and operational reliability. Fiberglass ducts, as a type of duct inte

In energy-saving retrofits of existing buildings and industrial systems, the selection of insulation materials is often constrained by factors such as limited space, complex construction conditions, and the need for uninterrupted production. Against this

In building HVAC and equipment insulation projects, anti-condensation performance is one of the important indicators for evaluating the practicality of insulation materials. Glass wool is widely used for duct, pipe, and equipment insulation, and it has ce

Rock wool, a commonly used inorganic fiber insulation material in building insulation projects, is widely used for exterior walls, roofs, pipes, and equipment insulation due to its excellent fire resistance, good thermal and sound insulation effects, and

Rubber-plastic pipes (rubber-plastic insulation pipes) are widely used in air conditioning chilled water, refrigerant pipelines, and water supply and drainage systems due to their good flexibility and stable anti-condensation performance. However, in actu

LNG elastic felt is mainly used in liquefied natural gas pipelines, cryogenic storage tanks, and cryogenic equipment, with long-term operating temperatures down to approximately -160℃. The cryogenic conditions necessitate careful consideration of the ma

In ventilation and air conditioning systems, the sealing performance of duct systems directly affects air delivery efficiency, energy consumption, and operating noise. As a system integrating insulation and ductwork functions, the sealing performance of f

The application of aerogels is gradually increasing in building energy conservation, industrial insulation, and high-temperature or space-constrained scenarios. However, due to their diverse types and significant differences in technical parameters, impro

Glass wool is widely used in building insulation, HVAC, and industrial equipment insulation. However, improper selection, construction, or maintenance can easily lead to several typical problems. The following systematically explains these common problems

In various fields such as building energy conservation, industrial equipment, and pipeline insulation, the selection of insulation materials directly affects the system's energy efficiency, comfort, and safety. Rock wool, as an inorganic fiber insulat

Rubber and plastic insulation materials are widely used in HVAC, water pipe, and refrigerant piping systems due to their good flexibility, low thermal conductivity, and stable anti-condensation performance. The quality of their construction directly affec
