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 wipe down 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!
