  • Vinyl is a shorthand for polyvinyl chloride (PVC), which is a type of plastic. 
  • Fiberglass is made from a glass foundation that is heated at a high temperature and then pulled onto incredibly fine fibers that are then bound together. 
  • Fiberglass is impregnated with different resins and pressed into form if it is meant for sturdy construction, such as window frames.

Fiberglass vs Vinyl Windows: Durability

Both fiberglass and vinyl are extremely sturdy, durable, easy-to-care-for, and water-resistant fabrics that outlast wood. While wood is still the gold standard for window frames and sashes, owing to its lovely, classic appearance, it takes a lot of upkeep to maintain its good looks and avoid wear and tear.

Fiberglass allows for a greater variety of architectural possibilities.

Although both materials appear similar from afar and can be very appealing, fiberglass has a wider range of window appearances. Fiberglass frames are somewhat smaller than vinyl frames, leaving more glass exposed—ideal for letting in as much natural light as possible.

Although all products are available in a variety of colors, fiberglass can be painted whereas vinyl cannot. Finally, although vinyl is usually flat, fiberglass can be textured to look like real wood.

Although fiberglass windows are generally less expensive than wood windows, vinyl windows are typically less expensive than both.

Vinyl will save you anywhere from 10% to 30% depending on your position and the size and amount of windows you have. When you know that repairing a wooden window will cost up to $1,000, this will quickly add up.

Vinyl and fiberglass both outlast wood because they don’t rust or decay when exposed to moisture or insects, but fiberglass is the most durable choice. A high-quality vinyl window can last for up to 30 years, while its fiberglass equivalent can be used in your home for up to 50 years.

Fiberglass is more resistant to warping and cracking than vinyl and can withstand extended temperature extremes. Since vinyl stretches and contracts with changing temperatures, the seal between the window frame and the glass pane will crack in the harshest climates, drastically decreasing the window’s insulating abilities.


Vinyl and fiberglass windows are obviously less costly than wood windows, but vinyl is the lesser expensive choice of these two. Vinyl windows are between 10% to 30% less expensive. A single vinyl window costs $700 to $800 to install, while a single fiberglass window costs $900 to $1,100.

Do-It-Yourself Installation

Vinyl windows have a distinct advantage in that they are relatively easy to source and install for do-it-yourselfers. Fiberglass windows, on the other hand, must be mounted with extreme accuracy due to the rigidity of the construction, which necessitates tight tolerances.

  • Any kind of new construction or replacement window should be installed by a professional. Professional installation is almost always needed for fiberglass windows.
  • Any fiberglass window makers may be hesitant to market their products directly to homeowners, and they may not be warranted if they are not installed by a licensed contractor.
