We need two dimensions for each window in your your estimate, rounded to whole inches. You'll capture production-quality measurements once you're ready to order.

Here’s how:

window insert installation

STEP 1

Identify the place in your window to install your insert. Some windows have more than one frame step, shown above in blue and yellow.

STEP 2

For the inserts to fit there must be at least 5/8″ of flat space all the way around. Measure width and round up to the nearest inch.

STEP 3

The frame step must be unobstructed by window hardware or blinds. Measure the height and round up to the nearest inch.

When deciding where you'll install your insert, it's important to choose a frame step at least 1/2" from the window glass to maximize performance. If you want your inserts to block outside noise, the inserts should be installed in a frame step that's at least 1-4" from the window glass - the greater distance from your window - the more noise reduction you'll experience.
