Benefits of Fiberglass Windows

Fiberglass windows cost more than some other home window replacement options, but the many benefits they offer make them a smart investment. In addition to an attractive appearance, top features of fiberglass house windows include:

  • Durability: Fiberglass is about eight times stronger than vinyl and isn’t susceptible to rust or corrosion. Very little maintenance is required to enjoy years of performance from your Southern California fiberglass windows.
  • Energy Efficiency: The low heat conductivity of these replacement windows makes them highly energy efficient, so you can save money on your heating and cooling bills while also reducing your carbon footprint. 
  • Environmentally Responsible: In addition to reducing your energy use, you’ll also appreciate the fact that fiberglass windows require 80% less energy to manufacture than some other options. Plus, the windows are recyclable.
  • Many Style Options: Choose from dozens of colors, styles, hardware options, and other features to create a look that will complement the other design elements of your home.
