Window Profile

This is generally regarded as being one of the most important features of a window. Not only is it super important when it comes to maintaining the aesthetic appearance, but it’s actually vital when it comes to performance. When we say performance we’re talking about how well it controls airflow, temperature, light, sound, and so much more. Generally, the height of your windows determines how much light comes into your home, whereas the type of windowpane determines how much temperature is controlled. Looking for a low profile frame? Perhaps try a slider hung window or even an end vent. If you’re perhaps looking for the exact opposite, meaning a really tall or wide frame, you’ll want to try a casement window or an awning window. Both are excellent options that perform well and look great. The same goes for the hung and end vent windows. The below table displays some of the math pertaining to the matter. Keep in mind that this table is regarding fixed picture window calculations.

When it comes to Vinyl casings, most of them are about 2 and ⅝ inches or 3 and ⅜ inches. Typically the size of your brickmould will determine the size of the casing, but we’ll get to that in a moment. Overall the casing size is an excellent way of determining the standard size of a window. Dimensions always differ between manufacturers, so keep that in mind when looking at all of our calculations here.


As we previously mentioned, the size of your brickmould plays a large part in determining how large your Vinyl casing is. Overall, to put an explanation of Brickmould into perspective, it’s basically a strip of material. It’s on the outside of your window and is generally used to get rid of the space in between the wall and your window frame. It does this by actually filling the gap. This is super important because it stops water, air, and dirt from entering your home. It helps control temperature as well, for without it air would flow freely in and out of the house.

Jamb Extensions

Jamb Extensions are what adds length or width to the jamb, hence the name! Basically, by working closely with the jamb, you’re securing the window once the casing’s been placed. Overall the actual size of your jamb extensions depends on how big your actual windows are. If you’re walls or a 2 by 4 construction, generally we would recommend you get your jamb to be as thick as 1 ⅜ inch inches.

Canadian Window Size Regulations

Similarly to most things in Canada, there are regulations you need to follow. Depending on what type of window you plan on installing, you’re going to need to make sure it performs appropriately. This means you’re going to need to make sure it fits the minimum size as well as the maximum size. Some windows have special conditions attributed to them, whereas others don’t.
