Fibreglass has a long lifespan. It might be colored, gleaming, or drab. It is low-maintenance, anti-magnetic, fire-resistant, electrically insulating, and waterproof. The drawback is that it must be re-gel coated every five years and might cause airborne fibers, which may be a difficulty for asthmatics. Fiberglass is used in the manufacturing of boats, cars, planes, and other products where strength and resistance to weather conditions are important. It is man-made and can be color-fast. Fiberglass is commonly used as a replacement for wood in sports equipment because it is lighter weight and more resistant to damage. For example, tennis rackets and golf clubs have been made from fiberglass since they were introduced into the market in the 1960s. Fiberglass is also used instead of metal for fishing rods and surfboards because of its light weight and ability to retain its shape under pressure. However, fiberglass is known to release small amounts of toxic substances when heated or burned. These substances include arsenic, cadmium, chromium, and nickel. Fiberglass has become one of the most popular material choices for home improvement projects because it is easy to work with, looks good, and lasts longer than other materials. It is also used by architects to create decorative elements for buildings and public spaces. However, fiberglass contains chemicals that can leach out under heat or sunlight.
