Grid vs. No-Grid Windows: An Architect’s Point of View

Note: This article was written by Jerry Kommrusch, our architectural designer.

As an architect with Robbins Contracting in Colorado, I’ve had the pleasure of designing custom homes that reflect our clients’ unique tastes and lifestyles, as well as many that have been built into lavish communities. Windows plays a crucial role in a home’s aesthetic and functional aspects. One of the most frequent questions I encounter is whether to choose grid or no grid windows. This decision impacts a home’s overall look and feel, making it essential to consider various factors, including architectural style, personal preference, and practical considerations.

In this article, I’ll discuss the pros and cons of grid versus no-grid windows, offering insights from my experience working on diverse home projects. By the end, you should understand which option might be best suited for your custom home.

The Short Answer: Grid or No-Grid Windows?

Choosing between grid and no-grid windows largely depends on your home’s architectural style and personal taste. Grid windows typically suit traditional and historical styles, adding character and detail, while no-grid windows offer a sleek, modern look and unobstructed views, perfect for contemporary designs.

A Detailed Comparison

Grid windows, also known as windows with grilles or muntins, feature narrow strips of material that divide the glass into smaller panes. These grids can be made of wood, vinyl, or metal and are often used to create a traditional or historical look. For example, Colonial, Cape Cod, and some Colorado Rustic homes, with their square, symmetrical designs, benefit from adding grid windows, which enhance their formal and classic appearance​​.

Grid patterns vary widely, from simple squares to more intricate designs like diamond patterns found in Tudor and Victorian styles. These grids add visual interest and align with the architectural details and historical accuracy of these home styles. Additionally, grid windows can provide a sense of charm and nostalgia, evoking the craftsmanship of earlier architectural eras.

No-Grid Windows, on the other hand, offer a clean, modern aesthetic. These windows provide unobstructed views, allowing maximum natural light and a seamless connection between indoor and outdoor spaces. This style is particularly popular in Modern, Contemporary, and Mid-Century Modern homes, where simplicity and functionality are key design principles​.

The absence of grids emphasizes the sleek lines and minimalist approach of these architectural styles, making them ideal for homeowners who prefer a more streamlined look.

Architectural Styles and Window Choices

Colonial and Cape Cod homes are known for their square, symmetrical, and formal designs. These styles often incorporate grid windows to enhance their traditional aesthetic. Double-hung windows divided into four, six, or even more panes fit perfectly within the symmetrical lines of these homes, creating a classic colonial grille pattern. This design complements the architecture and adds a sense of historical charm and detail to the home.

Tudor-style homes, with their distinctive exposed timbers and stucco or brick facades, often feature clustered casement windows with diamond-pattern grids. These intricate designs echo the crisscrossing timbers and enhance the old-world European charm of Tudor architecture. Victorian homes, another traditional style, are characterized by their decorative and ornate features. Grid windows with diamond patterns or more intricate designs on the top panels, combined with plain lower panels, add to the elaborate and embellished look typical of Victorian homes.

Modern and Contemporary homes favor a minimalist approach, often opting for no grid windows to maintain clean lines and unobstructed views. The sleek, uninterrupted glass surfaces align with the principles of simplicity and functionality central to these styles. Mid-century modern homes, which span from the mid-1930s to the mid-1960s, also embrace the no-grid look.

While these styles prioritize function and simplicity, they can still incorporate grid patterns for added detail if desired. However, the emphasis remains on maintaining the streamlined appearance and enhancing the home’s modern aesthetic.

Craftsman and Bungalow homes are known for their charming and custom details, such as covered front porches and tapered columns. These homes often use a hybrid approach to window design, with grid patterns on the upper sash of double-hung windows and plain lower sashes. This combination provides a balanced look that complements the architectural style without overwhelming it with too much detail​.

Practical Considerations

Energy Efficiency 

Double or triple-glazed windows with low-E coatings and gas fills provide excellent insulation regardless of the presence of grids. However, grid windows might have a slight edge in reducing heat transfer due to the additional framing material, which can improve thermal performance in certain designs.


No-grid windows are generally easier to clean and maintain because there are no muntins or grilles to collect dust and dirt. Their smooth surface allows for effortless cleaning with fewer nooks and crannies. In contrast, grid windows require more attention to detail during cleaning, as the individual panes and grilles can accumulate grime​.

Customization and Cost 

Grid pattern customization options are extensive, allowing you to choose from various styles and designs that match your home’s architectural features. However, this customization can come at a higher cost due to the additional materials and labor involved in creating the grid patterns. No-grid windows, being simpler in design, are typically less expensive and easier to manufacture and install​.

Final Thoughts on Grid vs. No-Grid Windows

From an architectural perspective, the decision between grid and no-grid windows is influenced by several factors, including the home’s architectural style, personal preferences, and practical considerations such as energy efficiency, maintenance, and cost. Grid windows are well-suited for traditional and historical styles, adding character and detail, while no-grid windows offer a sleek, modern look and unobstructed views, ideal for contemporary designs.
