MEASURE YOUR WINDOWS

Use a tape measure to measure the width & height of your window frames in inches. Your measurements don't need to be exact for this step - once you're ready to order, we'll provide you with the tools and instructions to get precise measurements and qualify for our Snug Fit Guarantee™.

Step 1

Some windows have more than one frame step, shown above in blue and yellow. The best frame step for installing an insert has 5/8" of flat, unobstructed surface.

Step 2

Measure the width of the base of your window frame. Round up to the nearest inch.

Step 3

Measure the height of one side of your window frame. Round up to the nearest inch.
