Common questions

  1. What is Fibreglass? Fibreglass is a lightweight, durable and corrosion-resistant material composed of thin glass fibres bound together with a plastic resin. It is often used for insulation, roofing, boat building and other construction materials.
  2. What are the advantages of Fibreglass? The main advantages of Fibreglass are its lightweight, durability, corrosion-resistance, and fire-resistance. It is also easy to shape and install, and cost-effective compared to other materials.
  3. What are the different types of Fibreglass? There are several different types of Fibreglass, including woven, non-woven, and stitched. Woven Fibreglass is the most common type, as it is the strongest and most flexible. Non-woven Fibreglass is also popular, but it is not as strong as woven Fibreglass. Stitched Fibreglass is the least common type, and is often used for insulation or marine applications.
  4. What are the different applications of Fibreglass? Fibreglass is used in a variety of applications, including insulation, roofing, boat building, automotive components, aerospace components, and more.
  5. What are the safety precautions when using Fibreglass? When working with Fibreglass, it is important to wear protective gear, such as goggles, gloves, and a face mask. Inhaling the dust generated by cutting Fibreglass can cause respiratory problems. It is also important to read all safety warnings and instructions that come with Fibreglass products.


Fibreglass is believed to have been invented in the late 1930s by a Russian-born American chemist called Vladimir K. Zworykin. It is said that he was inspired by the idea of making a lightweight, waterproof material from glass after noticing how seaweed had been able to cling to glass surfaces. Zworykin then experimented with glass fibers, eventually leading to the invention of fibreglass. This discovery revolutionized many industries including architecture, housing, and transportation. Fibreglass quickly became popular because of its ability to be molded into any shape, its extreme strength, and its durability. It is still widely used today and continues to be an important material for many industries. [Source](
