What Are the Advantages of Fiberglass Windows?

Fiberglass windows offer a number of benefits to prospective window buyers that other window varieties do not.

While all types of windows today can incorporate energy efficiency features to decrease your home’s energy consumption, none can match the energy efficiency benefits offered by fiberglass frame windows. Fiberglass is a very poor conductor of heat, meaning very little heat will transfer into your house in the summer time and very little will transfer out in the winter months.

Fiberglass is also a very resilient material that is not susceptible to extreme temperatures. In fact, fiberglass will expand and contract 800 times less than vinyl in extreme temperatures. This is advantageous because it means that your windows will fit snugly in the frame year round—minimizing airflow into and out of your home from around the frame.

Finally, fiberglass requires virtually no maintenance. Fiberglass won’t warp, fade, crack, rust, or rot like wood or vinyl windows. With a simple wipe down, fiberglass windows should look like-new for years!

Great company that backs their product. We built a new house and Quality Window & Doors was the subcontractor for our Weathershield windows and doors. Wayne and Noe came out to service a broken handle on our 16' Weathershield sliding door. We were technically beyond the warranty period but they repaired the handle for free. They also took the time to go around and adjust our other exterior doors to make sure they were well aligned now that the house had settled a bit. Wayne was a real expert and got all the doors adjusted and working perfectly!

We are thrilled with our new windows and door! Excellent job from estimate to completion! The install team was fantastic and I loved that the lead installer was also present during the initial measurement phase. It took a few months for the windows to arrive so it was really nice to see a familiar face for the install and he knew exactly what to do! Highly recommend!!

QWD is a first rate company. The staff from product selection, estimate, showroom, measurement and installation were professional and highly competent. The installation crew paid attention to detail and went through great lengths to ensure our satisfaction. I love the new windows and I recommend them without reservation.
