Custom Windows

What are Custom Windows?

Custom windows come in an endless variety of sizes, shapes, and styles. They can even be made to order, allowing you to choose windows that improve the look of your home while also improving energy-efficiency. Expertly installed, custom replacement windows are more likely to achieve your design and energy performance goals than windows you buy off the shelves of big box stores because they are made specifically for your home.

Customization options include size and shape, as well as insulated glass packages and decorative elements like privacy glass, stained glass, and grids. Made-to-order replacement windows offer you the freedom to choose windows based on your home’s specific needs, whether it’s improved efficiency, unique design features, or a precise size for a more weathertight fit.

Perfect Fit:  Sometimes, when clients walk into our showroom they are surprised to learn that we don’t keep windows in stock. We order custom-sized windows made individually for each project ensuring that each window fits just right. Not all windows or window openings are the same size, ordering made-to-order windows minimizes mistakes and air leakage problems. Custom windows can be made in virtually any size and shape to meet your needs, your choices will depend on the vendor.

Energy Efficiency:  The potential energy benefits of custom windows are tremendous. For this reason, energy upgrades are some of the most popular window customizations. These include windows with insulating gas between the panes, glass coatings, or upgrading to a triple-pane design. If you’re upgrading a house full of single-pane window units you’ll notice an immediate difference in comfort and energy costs.

Custom Windows FAQs

At BM Windows and Doors, we know choosing the right windows can bring up a lot of questions.
That’s why we’ve put together this helpful FAQ section so you can get clear, straightforward answers

What are custom-shaped windows?
Custom-shaped windows are specialized units designed in unique geometric profiles—such as arches, circles, triangles, trapezoids, and more. At BM Windows & Doors, these are tailored to fit your specific architectural vision, allowing you to add a distinctive, high-end look to your home that standard rectangular windows cannot provide
What are the benefits of choosing custom-shaped windows from BM Windows & Doors?

Our custom designs combine artistic flair with the structural integrity of our high-performance window systems:

  • Precision Engineering: Every shape is custom-manufactured to fit your home’s rough opening perfectly.

  • Durable uPVC Frames: We use a 100% lead-free, high-impact uPVC compound that resists warping, cracking, and UV fading.

  • Architectural Versatility: From elegant rounds to sharp-angled rakes, we can match almost any design requirement.

  • Maintenance-Free: Our frames never require painting or staining, regardless of how complex the shape is.

Do custom-shaped windows provide energy efficiency?

Absolutely. Because most custom-shaped windows are “fixed” (non-operable), they have fewer points for potential air leakage. When built with our Cardinal LoE glass and fusion-welded frames, they offer superior thermal insulation and meet strict energy standards.

Can custom-shaped windows be combined with operable windows?
Yes! A popular design choice is to “stack” a custom-shaped window (like a half-round or transom) on top of an operable casement or double-hung window. This allows you to maintain the unique architectural shape of your home while still enjoying fresh airflow.
Are custom-shaped windows more expensive?
Because they require specialized manufacturing, custom bending, and unique glass cutting, these windows typically have a higher price point than standard shapes. However, they significantly enhance your home’s curb appeal and interior character, which can increase overall property value
Can I customize the color and glass of my shaped windows?
Definitely. We offer a wide range of interior and exterior color finishes to match your existing décor. You can also customize the glass with various LoE coatings for energy savings, or choose decorative grille patterns and privacy glass textures
How do I clean and maintain a custom-shaped window?
Since these windows have no moving parts or hardware, maintenance is minimal. The uPVC frames only require an occasional wipe with mild soap and water. For high-reach shapes, such as those in vaulted ceilings, a telescopic cleaning tool is usually the most effective solution.
