Fiberglass Windows vs Wood Window Frames – From Maintenance To Durability, Fiberglass Is The Clear Choice

Do you love the traditional look of wood-framed windows but dread the maintenance involved in keeping wood frames in good repair? Fiberglass windows are the perfect solution. Fiberglass has the look of wood without the required upkeep that goes along with wood frames. 

3 Clear Benefits of Fiberglass Windows


Unlike wood, which can have all sorts of hidden secrets like dry rot, fiberglass won’t rot or decay. As long as your fiberglass window frames are in good condition, you shouldn’t have to worry about your windows deteriorating; that’s why we call them worry-free! 

Fiberglass also resists termites. Bugs tend to gain a foothold in old wood that has started to decay, but they won’t go near fiberglass. We call that tremendous peace of mind! 

Fiberglass is also easy to clean. Exteriors can be sprayed down with a hose and scrubbed without worry about damaging the material, where wood must be treated with greater care. 

Fiberglass is also incredibly strong, so it can safely hold larger panes of glass without worry.

In hot climates, fiberglass frames are insulated to help increase their R-value. Fiberglass can expand and contract with weather changes. 

In humid climates, fiberglass won’t rot when it’s damp for long periods. Additionally, it’s easy to clean moss and dirt buildup from outside. 

Wood windows can be tricky in cold climates because wood can’t flex when frozen, which can cause drafts. Also, the difference between heat inside and cold outside can cause condensation, leading to rot. 


Fiberglass comes in several premium colors. These are permanent colors that will never fade, chip, or wash away. Finding a custom color that fits your home is easy.

If you can’t find the exact color you need or if you want to upgrade your older fiberglass windows, fiberglass is also paintable. Because it’s paintable, you can truly customize the look of your home any way you like, as often as you like. 

Upgrade your traditional look by choosing fiberglass window frames for your next project. They make excellent replacement windows, and they are beautiful on new builds as well. Because they sport a traditional look, are maintenance-free and climate-friendly, and come in an array of customizable colors, they are often a much more practical alternative to wood.
