What Are the Benefits of Fiberglass Windows?

First introduced more than 20 years ago, fiberglass windows have made leaps and bounds and now hold a place firmly among more traditional window materials such as wood, vinyl, and aluminum. Some of the benefits of fiberglass windows include:

  • Strength – Fiberglass windows need no reinforcement, and a high strength-weight ratio means you get added structural strength without added weight. It’s hardness allows for smooth hardware operation and benefits home security features
  • Insulation – Fiberglass is one of the most effective insulators on the market, with a low heat transfer rate and a low U-Value
  • Design Flexibility – Fiberglass’ tensile strength allows slimmer designs with larger glass area, providing more natural light and enhancing heat gain during the colder months.
  • Durability – Fiberglass is not affected by moisture, extreme heat, cold, or acidic conditions. It does not degrade with exposure to UV rays, salt, or chemical or acid rain and it has an 80 year life expectancy.
  • Energy Efficiency – Fiberglass manufacturing requires less energy to manufacture than other materials, generating less waste than other materials during the manufacturing process. Fiberglass is an insulating material and does not require a thermal barrier like most other types of windows. Additionally, fiberglass windows expand and contract at much lower rates than aluminum or vinyl, meaning reduced air leakage and lower energy bills.
