The size of replacement windows can vary considerably depending on the type and material used for the construction. Some replacement windows are designed with self-fitting tabs so that they can be cut to size without any measuring or templates. In cases like this, you will need to measure the width of your existing window and then find a comparable replacement window with a similar width.
In most instances, you will need to accurately measure the existing window to know what size window you need. Measuring your windows for replacement can be a tricky process. Regulations may vary depending on the size of your windows and how old they are, so it’s important to do some research before you start the project.
In this article, We’ll show you exactly how to measure your windows to find out how much insulation you need for installation purposes.
Fundamental Things To Do
The first step is to stand back from the window and take a close look at the sashes from top to bottom. Make a note of their measurements, so you’ll know exactly how much area you need to cover with insulation.
Next, you will want to measure the thickness of your windows and make a note of this measurement as well. This will allow you to purchase the correct amount of insulation for each window with an identical size.
If your windows are older than 10 years, they should already have air space between each sash. If the sashes are still tight, you can make an opening between the sashes using a utility knife.
Use a measuring tape to check and see if your window sashes are at least 1/2 inch apart. If they are not, you will need to add more air space before you begin insulating them.
Take a look at your window panes. If you have double-pane glass, these will also need to be covered with insulation and the air spaces in between.
Calculate Insulation Needed to Ensure Proper Comfort
Once you have measured your windows, it’s time to take a look at the space between the panes. You will need to calculate how much insulation you need to use to ensure proper comfort for your occupants.
To calculate the correct amount of insulation needed for your windows, you need to take a look at the thermal advantages and disadvantages of each type of replacement window. Consult with a reputable replacement window company for more information.
How to Measure Window Width
Measure the width of the window in three places: at the bottom, at the middle, and at the top. To measure the width of your windows, you will need to find a sash that is approximately double your measurements. Measure the space between panes with a ruler or tape measure, and then use this measurement to find a comparable replacement window of the same size.
You should usually use a tape measure to get the width of all your windows, but you could also use a ruler. If you choose this method, it’s important to consistently measure from the same point on your window to ensure that you get an accurate measurement every time.
How to Measure Window Height
To measure the height of a window, you’ll need to take three measurements again. Measure from the top board of the window frame to the bottom sill. A trio of measurements, one on each side of the window and one in the middle, would be most advisable.
Most likely, a window’s height will be measured in the same way as its width. In this instance, you will need to measure two sash widths and two sash heights until you find a comparable replacement window with the same measurements.
How to Measure Window Panes
Take a look at your existing panes. Use a tape measure or measuring tape to measure from scratch the area of each pane. It’s always best to add additional inches in order to account for any air space that may exist between panes. In this instance, you will need to measure two panes on either side of the window and one in the middle. Subtract these measurements from your existing measurement, and then find a comparable replacement window of the same size.
For your replacement windows, remember that double-pane windows should have triple panes for a proper insulation barrier.
As you can see, measuring your windows for replacement is not nearly as complicated as it might seem. In most cases, it’s just a matter of getting the measurements right.
The cost of insulation varies depending on the type of insulation used and whether you are insulating a single window or multiple windows. For more information about our products, visit STL Windows and Doors.
