Indow window inserts block drafts, reduce noise, and save on your bills. But, how much do they cost?

Indow pricing is by the square foot and the grade type you select.


How to Measure For An Estimate


Getting an Indow cost estimate is simple.

Find a frame step (see image 1) that is at least 5/8″ and without any obstructions. Measure the width and height of your window along that frame, using a tape measure (image 2 & 3). 

Step 1:

Some windows have more than one frame step, shown above in blue and yellow. Identify the best frame step for the insert.

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.

For Indow inserts to fit:

There must be at least 5/8″ of flat space all the way around. 

The frame step must be unobstructed by window hardware or blinds.
