Glass features like floor-to-ceiling windows, a luxurious glass shower, or a glass dividing wall are guaranteed showstoppers. Recently, designers and homeowners have been using industrial gridded windows to create high-end design moments.
Known as Crittall windows, these windows feature black steel grilles (vertical and horizontal pieces connecting window panes) in a large grid pattern. Industrial Crittall-style windows are a blend of brutalist and contemporary design styles. They are strong and slim while still flooding a space with soft, natural light.
Used in porches, skylights, showers, and as room dividers, Crittall-style windows can become expensive quickly and often require a contractor for installation. If you love the high-end look but not the price tag, keep reading to learn how to DIY gridded windows at home for less than $10.

How to Get DIY Gridded Windows
Method 1: Electrical Tape
One of the cheapest and easiest ways to get the Crittall look without any heavy lifting is by creating grilles with black electrical tape. In her video on TikTok, Liz Lovery shows how to mimic the Crittall style for less than $5. To DIY the look at home, start by thoroughly cleaning the insides of your windows. Then, use a measuring tape, level, and a pencil to create small marks on the window sill where you want the panes to be.
Starting with the vertical lines, apply the electrical tape to the window. As you apply the tape, follow with a plastic scraper to remove any bubbles or bumps. Repeat the process for the horizontal lines. To remove the grid, peel off the electrical tape and wash the windows with warm water and dish soap. If there is leftover tape residue on your windows, gently scrub with a cloth and rubbing alcohol.
Method 2: PVC Trim
For a more built-in Crittall-style look, Mckenna Barry on TikTok suggests using PVC screen trim to create faux window grilles. Begin by cleaning your windows, then measuring and marking the placement for your vertical panes. Next, cut a piece of PVC screen trim to the length of your window to create the first vertical line. In her video, Barry recommends cutting the trim .5 millimeters longer than your measurement to ensure the trim looks built-in. Attach the trim to the window with a strip of double-sided 3M tape.
Repeat this process for the remaining vertical lines. Because the trim pieces are each .5 millimeters longer than your measurements, Barry notes the horizontal pane pieces shouldn’t require any tape. The tension between the vertical grille and the window sill will hold the piece of trim in place. Continue until you reach your desired look.
Method 3: Vinyl Molding
Another way to achieve the 3-D Crittall window look is by using removable vinyl molding. Anthony Immediato tried the hack in a TikTok video and gave helpful information on how to complete the project. Again, start with clean windows, and measure the height and width of your windows. Cut long strips of the vinyl molding, peel off the back sticker, and adhere the molding to your window. Choose to create both horizontal and vertical lines, or opt for one or the other for a more minimal look.
