High performing fiberglass windows offer a variety of tangible paybacks to homeowners. Here are a few of our favorite benefits of fiberglass windows:

1. Durable

Fiberglass windows are extremely durable and can last up to 80 years! They are much more durable than their competition such as wood, vinyl, or aluminum. Wood windows can absorb moisture, which can lead to wood rot. Aluminum can corrode, and vinyl isn’t as strong as fiberglass material.

Fiberglass windows stand up to extreme weather conditions. It is impact resistant (think hard hats and canoes—because they are fiberglass). While other window materials buckle or deform under pressure, durable fiberglass windows distribute the impact load and prevent surface damage. Fiberglass windows don’t warp, rot, rust, corrode, shrink, or crack. They hold up even when subject to extreme temperatures and wear.

2. Energy Saving

Energy efficient fiberglass windows are not only used in residential properties, but also in today’s new construction on high-end commercial buildings. They help decrease your utility bills as they keep the air conditioning inside during the summer, and heat inside each winter. They can actually decrease energy costs by 20%- 40%. They don’t expand and contract, and therefore decrease the possibility of the hassle of caulking cracks. When it comes to water infiltration, they offer year-round superior performance.

Indoor comfort abounds with fiberglass windows due to their superior insulation properties. When indoor temperatures are consistent throughout your home, it makes for a delightful home atmosphere—largely due to fiberglass windows. They decrease the need to bundle up under multiple layers of clothes indoors each winter, and keep you cool in the summer, making them a top choice for replacement windows in the DC area.
