Fiberglass, a ubiquitous insulation material, is crafted through a meticulous process of melting glass and extruding it into fibers. These fibers are woven into mats or fabrics, delivering insulation with notable density and thickness. Its thermal and acoustic properties make fiberglass a preferred choice in residential, commercial, and industrial settings, finding its way into walls, ceilings, attics, and appliances.

Mechanical strength:
Fiberglass has a specific resistance greater than steel. So, it is used to make high-performance
Incombustibility:
Since fiberglass is a mineral material, it is naturally incombustible. It does not propagate or support a flame. It does not emit smoke or toxic products when exposed to heat.
Electrical characteristics:ngs
Fiberglass is a good electrical insulator even at low thickness.
Dimensional stability:
Fiberglass is not sensitive to variations in temperature and hygrometry. It has a low coefficient of linear expansion.
Compatibility with organic matrices:
Fiberglass can have varying sizes and has the ability to combine with many synthetic resins and certain mineral matrices like cement.
Non-rotting:
Fiberglass does not rot and remains unaffected by the action of rodents and insects.
Thermal conductivity:
Fiberglass has low thermal conductivity making it highly useful in the building industry.
Dielectric permeability:
This property of fiberglass makes it suitable for electromagnetic windows.

Types and forms of fiberglass:
Depending on the raw materials used and their proportions to make fiberglass, fiberglass can be classified into following major types:
A-glass:
A glass is also called as alkali glass and is resistant to chemicals. Due to the composition of A glass fiber, it is close to window glass. In some parts of the world, it is used to make process equipment.
01
C-glass:
C-glass offers very good resistance to chemical impact and is also called as chemical glass.
02
E-glass:
It is also called as electrical glass and is a very good insulator of electricity.
03
AE-glass:
This is alkali resistant glass.
04
S glass:
It is also called as structural glass and is known for its mechanical properties.
