Glass is a remarkable material with distinct characteristics. It typically exists in an amorphous solid state, meaning it lacks a crystalline structure and behaves neither like a liquid nor a conventional solid due to its fixed, non-crystalline molecular arrangement.

These unique properties include transparency and a notably low degree of thermal expansion, as well as a low thermal expansion coefficient (CTE). Despite the expectation that amorphous materials might have a low melting point, glass retains its mechanical integrity at relatively high temperatures, making it an enduring and versatile construction material that has been utilized throughout human history.

In today’s world, a wide variety of glass types are available, each tailored to specific applications, thus necessitating a comprehensive understanding of their distinct behaviors. In the context at hand, glass is being used in the form of fibers as an insulating material for buildings.
