What Are Fiberglass Windows?

Fiberglass windows are a top choice when you're thinking about getting new windows. They're made from a mix of glass fibers and a special material called resin. This makes them tough and long-lasting. They are called "fiberglass" because the glass fibers are combined with the resin to create a super strong material.

One exciting feature of these windows is the material they are made of - Ultrex fiberglass. This material is stronger than vinyl. That means fiberglass windows can handle more wear and tear, making them a great choice for the long term.

Another great thing about fiberglass windows? They are stylish and can be custom-matched for every home. You can pick different styles and colors that suit your home. Whether you want a modern look or a classic style, fiberglass windows can make it happen. 

Why Choose Fiberglass Windows?

1. Weather Resistant

Denver's weather can be tough on windows. The beauty of fiberglass windows lies in their ability to expand and contract with temperature fluctuations. This feature makes them a fantastic weather-resistant option.

2. Eco-Friendly

Fiberglass window frames are made with glass fibers and resin, requiring less energy to produce than other window frame materials.

3. Energy Efficiency
