When it comes to your home, windows play a fundamental part. From allowing you to see outside, to letting light and air in, to considerably changing the appearance of both outside and inside your home, you can see just how important your windows are. With that in mind, when the time comes to replace your windows, it is important to weigh up your options carefully to ensure you make the right choice for you and your home. Both vinyl and fiberglass replacement windows are highly popular choices among homeowners and home improvement contractors alike. As both replacement windows options have their own unique set of pros and cons, it can be difficult for homeowners to decide between them. In this article, we will be outlining the important differences between them so you can better understand which option would best suit your home.
At a Glance – What are the Differences?
Before we get into the unique specifications of both fiberglass and vinyl replacement windows, let us take a quick look at the basic differences between the two.
Vinyl Replacement Windows
Advantages
- Can be cheaper
- No need to paint
- Easy installation
- Readily available
- Increases resale value of your home
Disadvantages
- Can bend and warp as temperatures change
- Does not offer superior air sealing
- Poor insulation in the frame without upgrading to foam filled
Fiberglass Replacement Windows
Advantages
- Great insulation, making it more energy efficient
- Does not warp as temperatures change
- Increases resale value of your home
Disadvantages
- Considerably more expensive than vinyl
- Can be difficult to install
- Requires regular maintenance
Durability and Strength
In terms of durability and strength, fiberglass is the superior choice. Fiberglass windows are stronger and more durable due to the fact that fiberglass frames are reinforced with glass fibers, giving it considerable strength. Furthermore, compared to most other window types, fiberglass has the highest resistance to rotting, warping and corrosion. Unfortunately, some cheaper vinyl windows tend to warp, crack and bow under the influence of weather conditions over time.
Energy Efficiency
When it comes to the energy efficiency of your home, the window type you choose is vital. When deciding between vinyl and fiberglass replacement windows, fiberglass windows are the more ideal choice as they offer very high energy efficiency. This is because fiberglass frames react to changes in outdoor temperatures in the same way as the glass pane. This essentially means all components of a fiberglass window are contracting and expanding at the same rate, making it a superior insulator when compared with vinyl. However, there are some premium vinyl windows that compare to the energy efficiency of fiberglass.
Upkeep
Both vinyl and fiberglass replacement windows are considered to be low maintenance. In saying that, both replacement window materials do require care over time. Fiberglass windows can fade or peel, and may need to be repainted, whereas vinyl windows do not require repainting or staining over their service life. However, low cost vinyl replacement windows can warp or bow, which eventually causes poor air sealing. This means vinyl windows need to be filled with caulk every so often to stop air flow coming inside and or escaping outside. In general, however, both vinyl and fiberglass replacement windows are quite durable materials.
Aesthetics
Although the majority of any type of window is made from glass, there are a few distinct differences between vinyl and fiberglass frames. Generally, fiberglass frames more closely mimic the look of wood windows, while vinyl window frames tend to be simpler. Another benefit to fiberglass frames is that they can be painted any color at any time, whereas once you have chosen a color for vinyl frames, they cannot be repainted – only replaced. Vinyl windows, however, do come in a wide range of colors and finishes that can match any style of home, from traditional to modern.
Installation
When it comes to installing replacement windows, vinyl materials are generally considered easier to install. This is because vinyl is a highly flexible material that expands and contracts easily. Fiberglass material is more rigid and does not expand and contract as much as vinyl, meaning it can be trickier to fit into a window opening, therefore taking more time. Either way, we recommend hiring a professional home improvement contract for the installation of either window types.
