5 Reasons to Choose Fibreglass Windows Over Vinyl

You may have heard the debate of whether vinyl or fibreglass make the best choice for your windows if you’re having a new home built or if you are doing a home renovation. Perhaps you have even gone over to a builder’s supply store or are seeking a home builder to consult with. Read on to see 5 reasons why fibreglass might be the option that’s clearly the best over the years and will have you looking at the brighter side of things. Pun intended.

Strength and Longevity

The expansion and contraction that comes from heating and cooling due to the changing temperatures are the same for the fibreglass window pane as it is for the glass in your window. This is because fibreglass is derived from the glass itself. This all translates to a solid window will have its risk of seal failure diminished significantly with the changing temperatures that we see in Toronto, as well as the rest of the lovely north that we reside in. In contrast, because vinyl windows have seams that are welded at the corners, and have different expansion and contraction rates than the glass window, you may see seal failure occurring in those areas. Structurally fibreglass is more superior in strength than their vinyl counterparts. They also require minimal maintenance; just a fresh coat of paint if want. Rest assured that with fibreglass, you will have a window that will not warp as it is more rigid, and you can expect it to be up to 9 times stronger than vinyl, and have a lifespan of at least an extra 38 years over the vinyl!

Environmentally Friendlier and Energy Efficient

Fibreglass windows are comprised using approximately 60% recycled glass. Vinyl windows are made of a material called polyvinyl chloride, or PVC. There have been many debates over the years about its eco-friendliness, however all that aside, they are still way harder to recycle than fibreglass at the end of its lifecycle. From an energy efficiency standpoint, fibreglass is the winner. This is because fibreglass windows will not contract with the changing temperatures which means that heating and cooling costs may be lowered as the heat is not entering or exiting your home from the window. As an added bonus, they are better for soundproofing too as they are sealed better than vinyl.

Increase Real Estate Value

It may not be a big boost in real estate value, but it’s still worth adding that fibreglass windows will make your home more desirable to potential buyers as they will feel that they are getting more durable, stronger, and long-lasting windows. This will mean to them that they likely won’t need a renovation to replace the windows anytime soon and that their new potential home will be more energy efficient due to the lack of seal failure which will prevent the heat and cold from coming in or leaving the house unwanted.

Choice for Customization

Whether you’re just doing a home renovation or having a custom home builder build your dream home, you will get the most options for different colors and finishes with fiberglass. In addition, you can even paint your fibreglass window if needed if you want it to be a very specific shade, or if you just get bored of the same color over the years - and let’s face it, you will have these windows a long time so you may want to switch things up!)


Fibreglass windows are stronger and less material is needed in the frame. This means that you will get more of the window glass in your window so you can get more sunshine in! Also, they have a neater finish because they are seamless and crisp with the seams not showing much. Vinyl windows are heat welded at the corners with the excess cut off, leaving them with a messy finished look.

Although economically vinyl windows might make the most sense as it is initially the more affordable option, you should strongly consider the benefits of choosing fibreglass over vinyl as the long term benefits outweigh the initial costs.
