Advantages of Fiberglass Windows

Fiberglass windows offer many benefits over other types of windows, including:

  • Energy-efficient – fiberglass insulates against heat transfer, keeping your home more comfortable and energy-efficient.
  • Low maintenance – unlike aluminum or wood windows that need frequent sanding and repainting to keep them looking pristine, fiberglass windows require virtually no maintenance. A simple wipedown with a rag should keep them looking like new for years.
  • Durable – fiberglass will not rot, chip, warp, crack, or fade like many other window materials. It is an especially good choice for homes in coastal or tidal regions, as it is not susceptible to corrosion.
  • Environmentally Friendly – fiberglass requires less energy to manufacture than vinyl or aluminum. As a nearly inexhaustible resource, fiberglass has a very small environmental footprint.
  • And more!

Fiberglass Window FAQs

What makes fiberglass strong?

Glass, by its nature, is not very strong and shatters easily. However, fiberglass for windows is a glass-fiber-reinforced plastic that is stronger than even steel or aluminum. This strength happens because the fibers in the compound carry the load of whatever is putting pressure on the glass, and the plastic resin helps distribute the weight throughout the product. As a result, it is strong enough to be driven over by a car without breaking.

How long do fiberglass windows last?

Fiberglass’s strength combined with the fact that it expands and contracts at the same rate as glass on the window means fiberglass windows last as long as 30 to 50 years without suffering seal failure. The strength means it’s hard to break, even with a strong impact. If you choose fiberglass, you don’t have to fear that baseball sent flying by the neighbor kids breaking the window frame.

Are fiberglass windows energy-efficient?

Yes, fiberglass windows are considered very energy-efficient. In fact, they are more efficient than vinyl windows and are often made from recycled glass, which adds to their eco-friendliness. If you want to choose an environmentally friendly window, fiberglass windows are an excellent choice!

How do I maintain fiberglass windows?

Fiberglass windows are quite durable. They don’t rust or rot, and they are not prone to warping. The only thing you need to do to clean them is rub the frames down with a mild detergent, water, and a cloth. You can also use a silicone lubricant to keep the tracks running smoothly.

Are fiberglass windows worthwhile?

While fiberglass windows have a slightly higher cost than vinyl when you install them, they will last longer and help you save money. This combination makes them a great choice as you seek window options for your home.
