What Window Parts Affect Standard Window Size?
When considering window sizes, it’s important to remember that there are a lot of parts that go in to a standard Canadian window. In taking a look at the parts that matter to window sizing there is:
The Jamb/Jamb Extensions
A jamb extension is a frame that fills the depth of the wall space from the inside face of the window frame or ” jamb” to the face of the wall. Jamb extensions are typically 3/4″ boards.
The Window Frame
The frame that holds together the whole window can vary in thickness and width. Ideally, you want to strike the balance between a slim frame that won’t hold the window together, and one that takes up too much room, partially obstructing the view.
The Glazing
Many window companies in Canada are starting to offer double-glazed and triple-glazed windows. Glazing indicates the number of glass panes inside. This, in turn, affects how much a window weighs, and the maximum size that it can be in order to support the weight.
The Casing
The casing is the trim around your windows. Depending on your home’s style, it can be adapted to look modern or classic and can differ in size.
The Brickmould
The brickmould frames the outside of the window, giving it a stylish finishing touch. When replacing a window, if the new window install is of a different size than the previous one, brickmoulds can be used to correct the problem.

How Do They Compare to Other Window Types?
How exactly do vinyl windows stack up against other window types on the market? Let’s take a look at some of the most popular options available.
Vinyl vs Fiberglass Windows
Both vinyl and fiberglass windows are solid options for your GTA home, but they do have some key differences. Both window types are strong and durable, both provide excellent energy-efficiency and low heat transference. Both PVC and fiberglass are non-corrosive, meaning they won’t rust or fade over time and they are generally resistant to water and extreme weather. When it comes to lifespan, fiberglass windows tend to last a little longer than vinyl, but you can expect to pay significantly more up-front. As compared to fiberglass, vinyl windows are easier to install and are more readily available on the market as well.
Wood vs Vinyl Windows
With so many challenges, wood windows are becoming a less popular window replacement option for new homes in Ontario. While they are easily customizable, aesthetically-pleasing and energy-efficient, wood windows typically have a much shorter lifespan and come at a much bigger price tag than do vinyl windows. As a natural material, wood is also prone to attacks by invasive species, deterioration, mold, and many other issues. Caring for your vinyl windows is generally much easier than is caring for wood windows.
