5 Benefits of Fiber Glass Reinforcements in Windows

April 29, 2021

All recent conversations about windows revolve around their energy efficiency abilities. Did you know that windows are responsible for most of the energy lost in a building? But, this may be due to the materials they are made of.

Windows having fiberglass frames offer a lot of benefits over traditional materials like wood, vinyl, or aluminum. A brief list of these benefits includes insulation, improved structural performance, design variability, and less energy usage.

Fiberglass is one of the best materials for window construction in Arizona. It is highly durable, can resist the elements, and uses up less carbon during manufacturing, usage, and beyond. The following benefits of fiberglass make it ideal for use in windows:

They Are Resistant to Corrosion:

Since fiberglass reinforced plastics (FRP) are resistant to corrosion, they provide a long-lasting service even in environments with rapidly changing temperatures. FRP is corrosion-resistant because it’s made with resin. The higher the amount of resin in the laminate, the more effective it will be.

In many cases, they are also the cheapest option, making them an economical choice for homeowners.

They Are Lightweight:

Given the strength of fiberglass, you’d be surprised to know how light it is. The weight to strength ratio for FRP is extremely low, while it provides the same performance as steel and aluminum in a much smaller quantity. Because of their lightness, fiberglass windows are easier to install and cost less, especially if installed on an existing structure.

They Provide High Performance:

Fiberglass is a highly durable material, making it ideal for use in homes located in Arizona. It can withstand high temperatures without falling apart, bending, or breaking.

They Are Cost-Effective:

One of the leading benefits of fiberglass reinforced plastic is that it’s priced lower compared to other materials. Fiberglass can be used in many different designs without worrying about availability and high raw material costs.


Fiberglass has a low thermal conductivity, which means it is about 500 times less conductive than materials like aluminum. This makes double glazed fiberglass windows a thermally efficient alternative to other materials.

By focusing on windows, homeowners can improve their house’s thermal performance and reduce the load on heating and cooling systems. This way, one can achieve higher energy savings without the HVAC.
