Fiberglass can be explained as a hardened plastic also known as glass wool. The plastic is manufactured through the enforcement of plastic using glass to produce a glass-fiber reinforced plastic. Therefore, the fiberglass insulation is making of the glass fiber for commercial use. The fiberglass material has excellent properties such as being weather proof and strong. Plastic manufacturing industries do use the fiberglass based on the composition and texture of the final product.

Fiberglass can be subdivided into two groups based on the method of manufacture. There is the continuous fiber that is used in yawn and textiles and the discontinuous variety that is used as blankets, bats, boards for filtration and insulation. Fiberglass was developed to replace the molded plywood that was used in aircraft radomes. These are dome shaped and weatherproof enclosure that protects a microwave such as radar.

A modern use of fiberglass is the manufacture of sports cars and boats bodies, where such models were developed in 1950s. This has made a big impact in the automotives industry. A variation of fiberglass referred to as carbon fiber is used in aviation industry. The material is strong and non-corrosive and possesses the required standards of weight and volume.

The glass wool is also an important asset in telecommunications industries for the shrouding of antennas. Here the glass fiber is used to cover the antennas due to its permeability to Radio frequency and its low signal attenuation properties. Attenuation is the gradual loss or decrease in intensity of signal strength through a medium.

Where signal attenuation does not matter, the fiberglass is used to cover signal transmission equipment. This is mostly applicable in making of steel and cabinet support structure where signal reception is not needed. Fiberglass can be molded or painted especially where the users want to create a blending with other surfaces. It is also used in making electrical insulators that most power industry products have. Protective gears such as helmets and masks are also made using fiberglass due to its durability and light weight property.

Industries also use the fiberglass to make different storage tanks for different storage function. Some fluids such as chemical and oils may require high volume capacities such as 300 tonnes. Such installations must however be made from strong combination of glass wool contents to ensure resistance and durability. Way of ensuring such strength is using strong woven filament type of a fiber.

The glass-reinforced and durable plastics are also used to make house-building raw materials such as the door surrounds, roofing laminate, window canopies and sills. These inputs for house construction are easier to handle compared to metallic or wooden materials, and are easy to install. Industries that manufacture house panels can also adapt the fiberglass insulation to reduce heat loss while acting as acoustics.

Another application of glass wool is the making of water transport pipes that suit the underground usage and above the surface installations. This is favored by the fact that fiberglass pipes are resistant to weather and are non-corrosive. This ensures that the drinking water is not infected with heavy metals. The last application of fiberglass is in textile industries where fiberglass can be used as both continuous fiber to make yawn or non-continuous fiber to make heat insulators or laminators
