Choosing the right windows for your home is a big decision, but when it comes to selecting window grids, many homeowners hit a wall. What do they actually do? Do I need them? And how do I choose the right style?
You're not alone if you’ve ever searched “What are window grids?”, “Are window grids outdated?”, or “Which grid style should I choose?” These are three of the most common questions we hear, and it makes sense. Grids can impact both the look and function of your windows, and there are more style choices today than ever before.
In this article, we’ll answer those top questions and walk you through the most popular grid styles —Colonial, Prairie, Modern, and Custom — so you can make a confident, informed decision for your home.
Window grids, also called grilles or muntins, are decorative bars that divide a window into smaller panes or sections. Traditionally, they had a structural purpose, holding together small panes of glass before large glass sheets were affordable or available. Today, grids are primarily decorative, used to add architectural character or replicate a classic style.
Do you need them? Technically, no, modern windows don’t require grids for structural integrity. However, if you're aiming for a specific aesthetic, historical charm, or design continuity, they can make a significant difference. They’re an optional feature that can enhance curb appeal or blend your windows into your home's design era.
In some cases, window grids aren’t just a design preference; they're a requirement. If you live in a condo, townhouse, or cluster home, your Homeowners Association (HOA) may have specific rules about exterior appearance, including the use of grids. These guidelines are often in place to maintain a consistent architectural style across the community. Before selecting your new windows, it’s essential to check with your HOA to see if grids are required—and if so, what style, pattern, or color is permitted. At Joyce, we can help ensure your windows meet these requirements while still reflecting your personal taste.
Short answer: They’re very much still in style when used thoughtfully.
While some traditional grid patterns may feel outdated on ultra-modern homes, the right style can elevate your exterior and add visual interest. The key is to match your grid choice with your home's architecture. For example:
Grids aren't one-size-fits-all, but when they fit, they really fit.
Let’s break down the four most popular grid styles we offer at Joyce and how they can transform your windows:
This is the most classic grid pattern, featuring small square panes often six-over-six or nine-over-nine.
Prairie grids create a wide perimeter border with open glass in the center—typically four rectangles in the corners with clear space between.
Modern grids are minimalist, with fewer lines—sometimes just a single vertical or horizontal bar.
Got a vision of your own? Joyce can help bring it to life. Custom grids can match historic designs, reflect a unique personal style, or complement custom architecture.
When selecting a grid style, consider:
