When the time comes to replace your home windows, you will need to choose the material those windows are framed in. There are a lot of options these days. Vinyl windows are popular, as are fiber cement windows. One material you might also come across is fiberglass. So, what are the major pros and cons of fiberglass as a replacement window material? Take a look.

Pro: They don't warp as the temperature changes.

In most regions, the temperature changes from season to season. This can be hard on some window materials, such as wood, as it causes them to warp and distort from their original shape. Fiberglass windows won't do this. Fiberglass holds its shape even when temperature and humidity levels change wildly.

Con: They have to be installed carefully.

Fiberglass windows are more rigid than other window types. The fiberglass has essentially no "give" and can't be forced into a shape. This makes fiberglass windows a little harder and more time-consuming to install, so the installer might charge you a little more.

Pro: Fiberglass window sashes are thinner.

Fiberglass is really strong, even when milled or molded quite thinly. As such, fiberglass window sashes can be made narrower than vinyl or wood sashes. This means that in each window, you get more glass and less sash material. That translates to a wider view and more sunlight coming into your space.

Con: They are expensive.

Fiberglass windows tend to cost more than vinyl windows. The exact price difference depends on your region and on the specific brands you're considering. But if you get a quote for vinyl windows and another for fiberglass, the fiberglass will almost always be higher.

Pro: They block sound well.

Fiberglass is a good insulator against sound. As such, replacement windows made from fiberglass are a good choice for homes near roads; they help block traffic noise. These windows may also help keep sounds inside your home from traveling outdoors. Parents tend to like them as they keep the neighbors from hearing their noisy kids playing band instruments or loud music. Of course, they help keep sleeping babies' bedrooms quiet, too.

Consider the pros and cons above to decide whether fiberglass replacement windows are the right choice for your home. You can visit a window showroom to look at some examples in person and get a better idea of the styles that exist. For more information, contact window installers near you.
