It's called fiberglass. What is fiberglass?
What is it made of, and why is it widely used in the construction industry?
glass fiber (formerly known as glass fiber) is a kind of inorganic nonmetallic material with excellent properties.

It is yelarite, quartz sand, limestone, dolomite, boraite, boraxite seven ores as raw materials through high temperature melting, wire drawing, winding, weaving and other processes made into,
The diameter of its monofilaments ranges from a few microns to more than twenty microns, equivalent to 1/20-1/5 of a human hair.
Each bundle is made up of hundreds or even thousands of monofilaments.
It is a kind of reinforcement material, in the process of GRG production, is the gypsum slurry and glass fiber constantly alternating, layer by layer overlapping, glass fiber helps to strengthen the gypsum block firmness, prevent the gypsum after solidification scattered
It is high temperature resistance, after testing, the temperature of 300℃ on the strength of glass fiber is not any effect
It has high tensile strength. The tensile strength of glass fiber is 6.3~6.9 g/d under standard condition and 5.4~5.8 g/d under wet condition.
It has good electrical insulation, glass fiber has excellent electrical insulation, is a senior electrical insulation material, also used in insulation materials and fire shielding materials.
It is not easy to burn, glass fiber can melt into glass beads at high temperature, in line with the requirements of fire prevention and control in the building industry.
It has good sound insulation, glass fiber combined with gypsum, can achieve good sound insulation effect.

Its price is cheap, no matter what industry, cost control is the most important link, the product with better price will certainly be favored.
Ok, so that's why fiberglass is widely used in the construction industry. Fiberglass is a very good alternative to metal materials.
With the rapid development of market economy, glass fiber has become an essential raw material for construction, transportation, electronics, electrical, chemical, metallurgy, environmental protection, national defense and other industries.
Because of its wide application in many fields, glass fiber has been paid more and more attention.
