Attach the adhesive velcro piece on the muntin top and bottom.I used an 8.5″ x 11″ piece of printer paper as a general idea for the size of the “squares” I wanted to create.
#EXTERIOR DOOR WINDOW GRID REPLACEMENT WINDOWS#
Larger windows may need more than 1 muntin.

So, in order to OPEN the window, you must remove the grids. I put all of the grids on the inside of the windows. S o technically, the window grids that I made are called muntins.īefore we dive into the tutorial, I want to give you a heads up about the way I installed these DIY window muntins on our windows. What is the difference between a mullion and a Muntin?Ī mullion is a heavy vertical or horizontal piece that adjoins two windows together and a muntin is the very narrow strips of wood that divide up the individual panes within a sash (sometimes referred to as lights or lites). This was a bit more difficult and I had to use a level to make sure the grids weren’t slanted. However, I made some DIY grids for our sliding glass door which required both vertical and horizontal grids. Our windows already have horizontal trim (window mullions) so I only needed to add vertical muntins to complete the look I was going for. Yes, I added window grids (window mullions) to our 30+-year-old windows. You don’t need any power tools either!Ĭan you add window grids to existing Windows? Yep! Adding mullions to windows is super easy and cheap if you follow my tutorial. See how I attached them in my tutorial below! I made some faux window mullions using wood trim from Home Depot and paint.

✅ I used these velcro pieces to attach the trim to our windows.
