In HVAC systems, the thermal conductivity of ducts directly affects heat and cold loss, system energy efficiency, and operational stability. As a composite duct type integrating structure, insulation, and sound absorption, the thermal conductivity of fibe

The reason aerogels can achieve "ultra-thin yet highly efficient thermal insulation" is not due to material thickness, but rather to their unique nanoscale microstructure and comprehensive suppression of all three modes of heat transfer.I. Why c

Glass wool is a widely used inorganic fiber insulation material in building insulation, HVAC, and industrial equipment insulation. Its insulation performance does not rely on the material itself "insulating heat," but rather on its unique struct

Rock wool is a widely used inorganic fiber insulation material in building energy conservation and industrial insulation. When evaluating the insulation performance of rock wool, thermal conductivity is one of the most crucial and valuable technical indic

In building insulation and HVAC systems, rubber and plastic insulation materials are widely used due to their flexible structure and stable performance. One of the important indicators for measuring their insulation effect is thermal conductivity. This ar

In the fields of cryogenic engineering and energy equipment, LNG (liquefied natural gas) systems place extremely high demands on insulation materials. These materials not only need stable thermal conductivity but also must maintain structural integrity un

In HVAC systems, air ducts not only transport air but also directly affect indoor noise levels. With increasing demands for acoustic environments in buildings, the sound insulation and noise reduction performance of fiberglass ducts has gained growing att

In the fields of building energy conservation and industrial insulation, rock wool is an inorganic fiber insulation material with a long history of application and mature technology. One of the core indicators for evaluating the insulation performance of

Among numerous thermal insulation materials, aerogel is often considered a representative material that "maintains significant thermal insulation effects even with extremely thin thicknesses." Compared to traditional glass wool, rock wool, or ru

Glass wool is a widely used inorganic insulation material in building envelopes, HVAC systems, and industrial equipment insulation projects. Many users focus on its thermal conductivity, fire resistance, and service life when selecting glass wool, but the

In the fields of building energy conservation, HVAC systems, and industrial pipeline insulation, rubber and plastic insulation materials are widely used flexible insulation products. Among them, the "thermal conductivity of rubber and plastic" i

In liquefied natural gas (LNG) storage and transportation, cryogenic pipelines, and cryogenic equipment systems, the thermal conductivity of insulation materials directly affects energy loss control and system operational safety. LNG elastic felt, as a fl
