Applications of glass wool include structural insulation, pipe insulation, filtration and sound insulation. Glass wool is a versatile material that can be used for wall insulation
In this article, we will demonstrate to everyone the ability to insulate and retain heat with and without the use of glass wool (also known as glass wool). In addition to the above two possibilities, glass wool can be used to absorb sound and reduce noise, used in car interiors, and insulate air ducts, and steam pipes,...
Thermal conductivity of glass wool:
Thermal conductivity is defined as the amount of heat (in watts) transferred through an area of material of a certain thickness (in meters) due to a temperature difference. The lower the thermal conductivity of a material, the greater its resistance to heat transfer and therefore the greater the effectiveness of the insulation.

In general, insulation is primarily based on the very low thermal conductivity of gases. Gases have poor thermal conductivity properties compared to liquids and solids, and therefore make good thermal insulators if they can be trapped (e.g. in a foam-like structure). Air and other gases are generally good insulators. But the main benefit is in the absence of convection. Therefore, many insulating materials (e.g. glass wool ) work simply by having a large number of gas-filled pockets, preventing large-scale convection.
The alternation of air pockets and solid materials causes heat to be transferred through multiple interfaces, causing the heat transfer coefficient to decrease rapidly.
