Reliability is crucial – not only in the construction of your fiberglass windows – but in the capabilities of the company you want to hire to replace your windows. That’s why in Arvada, Colorado, you should hire the most reliable home improvement company: 1st Choice Windows & Siding.

1st Choice seeks to be your first choice in window replacement services. From residential window services to commercial window services, we know plenty about vinyl window upgrades – much more than average window contractors.

Choosing Fiberglass Windows

Going with fiberglass as your window material is a tremendously valuable decision. Fiberglass windows are a much more durable and practical solution than average custom vinyl windows.

As energy-efficient windows, fiberglass allows for much better window insulation. That’s due to their window frames and window glazing, which are perfectly sealed to allow for maximum energy efficiency. You’ll see lower energy bills in only a few months of use.

Those features also allow for the best noise reduction windows. The outside world is a noisy place – especially if you live on a busy street. 1st Choice windows give you a much quieter environment.

We can’t go without mentioning how our fiberglass windows perform as UV protection windows, either. If you want the cleanest sunlight possible for potted plants, you’re in luck! The window design on this product provides the best sunlight for sustaining plant life inside your home.

“I could not believe how fast they got the job done and how well done it was! They obviously were very careful about every detail. The house looks fantastic and everyone I talked to at the company was great to work with. The guy who did the inspection for the people who bought our house even asked us who did the siding because they did such a great job!”

“Chris was an absolute gem to work with and the window suggestions were perfect. The home was built in 1962 and had all of the old steel frame windows which were losing energy rapidly. We noticed an immediate change in the environment inside the house and the outside looks fantastic. Great installers.”

“Window replacement was for our elderly mother and the professionalism of the entire 1st Choice team, greatly appreciated by the family - we did not have to worry that mom was being sold a 'bag of goods.' Love the new windows! Noise reduction, energy efficiency, look, all just great!”
