Silex Fiberglass Windows and Doors are Environmentally Friendly and LEED® Compliant

Fiberglass windows and doors are recognized throughout the industry as a “green” building material. Fiberglass is made from silica sand and non oil-based abundant natural resources. Our FiberFrame® fiberglass is made with partially recycled materials which require less energy to produce. In fact, the embodied energy required to produce fiberglass is considerably lower than vinyl, wood and aluminum. Using our products can provide points for LEED compliance projects.

  • Fiberglass is 3x stronger than wood
  • Fiberglass is 3.5x stronger than vinyl/wood composites
  • Fiberglass is 8x stronger than vinyl
  • Fiberglass has a near zero thermal expansion rate
  • Fiberglass has superior thermal performance and U-Values compared to aluminum

Fiberglass is an excellent material for performing in extreme hot and cold temperatures and will not absorb moisture, giving a lifetime of performance while looking great. In addition, our special coating system makes fiberglass virtually maintenance-free. All these features make SILEX Fiberglass Windows & Doors an excellent choice for projects such as commercial buildings, multi-family dwellings and more.

LEED® is a green building certification system that is internationally recognized. The LEED® third-party verification confirms that a building was designed and built to improve performance across several metrics, such as: energy savings, water efficiency, CO₂ emissions reduction, and improved indoor environmental quality. When you design with and specify SILEX products, you earn LEED® points for the following categories:
