Fiberglass Windows are strong, durable, and require little — if any — maintenance. While they may not feel as traditional as wood windows, they usually last longer and require less maintenance investments from homeowners. They can be installed in any climate, and they almost never chip, rot or warp. So, rather than worrying about repairing or repainting windows, you can simply relax and enjoy the view.
A small amount of fiberglass can support a heavy amount of weight. That’s why it’s the material of choice for building boats, bridges and even hardhats. Fiberglass is tougher and lighter than wood, and as low maintenance as vinyl window composites. Additionally, fiberglass is virtually unaffected by moisture and temperature fluctuations.
When you install fiberglass windows, your home will withstand every seasonal change, from cold winters to rainy springs and hot summers.
While there are other high-quality fiberglass window manufacturers to choose from, few compete with Marvin®. As an industry leader, Marvin continues to innovate wherever possible, boasting a patented, pultruded fiberglass.
The Marvin pultruded fiberglass materials are 8x stronger than vinyl windows and 3x stronger than vinyl/wood window composites. These energy efficient windows use insulated glass fibers, making them a top choice for window frame materials and window insulation.
Furthermore, the pultruded fiberglass remains stable in extreme temperatures. They expand and contract at nearly the same rate as glass. This allows the fiberglass to work with the glass and not against it. So, your fiberglass frames and windows will stay strong in harsh weather conditions.
