If your windows are looking a bit plain or outdated, there’s a simple and budget-friendly solution that can make a big difference—DIY Window Grids. Also known as grilles or mullions, these add-on features create the classic look of divided window panes without the cost or hassle of full window replacement.

At New Panes Creation, we specialize in helping homeowners achieve that custom, high-end appearance without needing to replace their existing glass. Our DIY window grids are designed for easy installation and a clean, professional finish—perfect for anyone looking to enhance their home’s style and curb appeal.

Whether you’re updating a single room or giving your entire home a fresh look, window grids are a smart, stylish upgrade that brings charm, character, and value—all without breaking the bank.

Why Add DIY Window Grids?

Builder-grade windows are common in many homes, but they often lack visual appeal. DIY window grids are an awesome way to:

• Add character to boring glass panes
• Create a classic or modern look (you pick the style)
• Get the charm of divided-light windows without paying thousands for replacements
• Increase curb appeal with just scissors and a tape measure

It’s a fast fix with big-time visual impact. No contractors, no headaches, no blowing your budget.

New homes often feature multiple pane (divided-lite) windows or French doors as do all drapery ads. Why? Because the treatment adds beauty, value, and charm to any home! You could buy expensive new windows with costly grid options, or try to make your own grids with complicated miter cuts with much difficulty – but now you’ve found the source! Beautify your home inside & outside at the same time. Add Insta-panes® to your existing windows and patio doors to give it the New Panes look!

This is the only product of its kind  that lets you quickly (using just a pair of scissors & tape measure) add today’s popular look to any size plain windows and patio doors at a fraction of the cost of new windows – or even the grid options! Insta-Panes® fit any style of window whether it’s a slider, cranker, or has metal or wood frames.

The white molded Geon® grids are attached directly to the glass with Knife Blade Clips®, Velcro® brand self-adhesive fasteners, or white super double-stick tape. They’re flexible and thin enough to work with all sliders. Note: Wood grids are too thick to work with ordinary sliding windows or doors, too stiff to remove easily, and require much maintenance. Our grids need no maintenance and can be removed easily!

This add-on window pane product will allow you to decorate any type of glass; whether it is a sliding glass door, sliding window, fixed glass window, picture window, cranker type window, transom window, double hung window, sidelights, casement windows, awning windows, or patio doors!

How to Plan Your Window Grid Layout

Before you stick anything on your windows, you’ll want a game plan. A neat way to visualize how you may want the divided lites to look is to take a bar of soap and draw the grid lines directly on the glass. This works really well, makes it easy to visualize, change up the design, and even cleans the window in the process!

1. Decide on a grid style: Do you like the classic colonial look? Maybe prairie style? Want something modern and horizontal? Just center crossbars? Totally up to you.
2. Measure your windows: Grab a tape measure and jot down the height and width of the glass (rough measurements are all that’s needed).
3. You can do the basic math or use our calculator on our website: www.newpanes.com/calculator or email us: info@newpanes.com

What You’ll Need

Here’s a quick checklist depending on your method:

Install Time! Let’s Do This

Whether you’re using our NewPanes kit or building from scratch, here’s a basic step-by-step:

1. Clean the glass – Start with a squeaky-clean surface. Dust and grime mess with adhesion.
2. Mark your layout – Lightly draw your grid pattern using a dry-erase marker.
3. Cut your strips – Measure and trim your grid pieces.
4. Stick them on – Press firmly from edge to edge. For best results, go vertical pieces first, then horizontal.
5. Step back and admire – You just leveled up your windows.

Some Helpful Tips

• If you’re painting your window frame (black looks AMAZING with grids), do it before installing.
• Don’t go too dark on vinyl windows—they can warp in heat. Use light colors or check your manufacturer’s guidelines first.
• If you ever want to remove the grids, just peel gently and clean the glass again.

Real Talk: Before & After

There’s something about adding grids that makes your windows feel intentional. Suddenly your house has style. It has symmetry. It looks like someone put thought into the design. And you didn’t even break a sweat or your bank account to do it.

Whether you’re updating your entry door, sprucing up a rental, or just want a fun weekend project—DIY window grids are the definition of small effort, big reward.
