Types of Windows in Commercial Design

Jun 4, 2025 | Blog

Windows do more than just provide a view to the outside. They play a critical role in connecting spaces, improving energy efficiency, enhancing aesthetics, and even boosting workplace morale. For commercial property owners and architects, the right selection of windows is vital for balancing form, function, and cost-effectiveness. Maximizing daylight through options like skylights can also reduce the need for artificial lighting, helping to lower electricity costs.

At South Coast Improvement Company, we understand the unique challenges and opportunities involved in commercial design. With a Design-Build service that eliminates conflict and streamlines the process, we pride ourselves on helping clients bring their visions to life.

This guide explores the various types of windows you can leverage for your commercial property, the factors to consider in choosing them, and how South Coast Improvement Company’s expertise can help create seamless, impactful results. Specialty windows and custom shapes are also available; custom windows can be designed to enhance architectural features and create unique, personalized designs for commercial spaces.

Introduction to Commercial Windows

Commercial windows are a vital component in any business environment, designed to maximize natural light, promote healthy air flow, and boost energy efficiency throughout the building. Whether you’re outfitting a modern office, retail space, or institutional facility, the right window type can make a significant difference in both comfort and operational costs.

There are several popular window types used in commercial settings, each offering unique benefits. Double hung windows and single hung windows are classic choices, with double hung windows allowing both sashes to move for flexible ventilation, while single hung windows feature only the bottom sash as operable for a more streamlined, cost-effective solution. Casement windows, which swing open on side hinges, and awning windows, hinged at the top and opening outward, are excellent for spaces that require enhanced air circulation and a tight seal against the elements. For projects with unique architectural requirements, specialty windows—including arched windows and custom shapes—can be designed to fit any vision.

Material selection is another key factor in commercial window design. Options like vinyl, aluminum, and wood window frames allow for a range of aesthetics and performance characteristics, ensuring compatibility with any architectural style. Energy efficiency remains a top priority, with advanced features such as low-E coatings and triple pane glass helping to reduce heat transfer, lower energy consumption, and maintain comfortable indoor temperatures year-round.

Customization is also readily available, from expansive glass panes that flood interiors with daylight to distinctive arched windows and other specialty windows that add architectural flair. With so many options, it’s easy to find the perfect window solution to meet your building’s functional and design needs.

Common Types of Windows for Your Commercial Space

Double Hung Windows

A double hung window offers versatility and a classic design that’s perfect for many commercial buildings. Both the upper and lower sashes are operable, allowing for improved airflow and easy cleaning. The sash slides vertically, providing flexible ventilation and making maintenance simple. Many double hung windows are ideal for spaces where functionality and traditional aesthetics are equally important.

  • Best for: Offices, retail spaces, and schools
  • Advantages: Easy cleaning, improved air circulation, balanced functionality, vertical sash slides for flexible ventilation and easy maintenance

Single Hung Windows

A single hung window has a simpler design. Only the bottom sash is operable, while the top sash remains fixed. This option is typically more budget-friendly while still providing good ventilation.

  • Best for: Budget-conscious commercial projects
  • Advantages: Cost-effective design, low maintenance

Casement Windows

A casement window is a popular window type that opens outward and is hinged on the side. Casement windows swing open, usually operated by a hand-crank or lever, allowing for full opening and excellent ventilation. This window type provides excellent ventilation and seals tightly when closed for better energy efficiency.

  • Best for: Spaces needing maximum airflow, like healthcare facilities or modern offices
  • Advantages: Excellent energy efficiency, excellent ventilation

Awning Windows

Awning windows, hinged at the top, open outward, offering a sleek and functional design. Their design prevents rainwater from entering the space, even when open, while still allowing fresh air to flow inside.

  • Best for: Coastal and rainy regions or areas of limited wall space
  • Advantages: Allows fresh air and ventilation during rain, energy-efficient seal

Picture Windows

A picture window is a large, fixed pane of glass designed to maximize natural light. Picture windows are fixed panes, meaning they do not open, but they offer unobstructed views and a clean, minimalist aesthetic. They function by framing the outside scenery, similar to a picture frame, making them ideal for showcasing beautiful outdoor views.

  • Best for: Modern commercial spaces or showcasing scenic views
  • Advantages: Abundant natural light, low maintenance

Sliding Windows

Sliding windows feature a space-saving design. They are easy to operate by sliding horizontally, making them ideal for areas with limited space.

  • Best for: Narrow spaces or where operable windows are needed
  • Advantages: Space-saving, easy to operate

Bay and Bow Windows

Bay window is a distinct product type offered by many manufacturers, often featured in their replacement and new construction window lines. Bay and bow windows extend outward from the building, creating additional interior space and offering a dramatic architectural element. Bay windows typically consist of a central fixed window flanked by two operable windows set at angles, and are commonly installed in reception areas, conference rooms, or customer-facing spaces to increase natural light and provide enhanced views.

  • Best for: High-end offices, restaurants, or customer-facing spaces
  • Advantages: Adds aesthetic value, maximizes space and light

Specialty Windows

Specialty windows are custom-designed to suit unique architectural styles or needs. These include arched windows, stained glass, as well as other specialty options such as custom windows for personalized designs, garden windows that extend outward to create a mini-greenhouse effect, jalousie windows for enhanced ventilation, glass block windows offering privacy and decorative appeal, and hinged windows known for their energy efficiency and ease of cleaning.

  • Best for: Showcasing unique brand identity or historical preservation projects
  • Advantages: Fully customizable, adaptable to specific design elements

Factors to Consider When Choosing Window Types

Energy Efficiency

Energy-efficient windows are essential for lowering heating and cooling costs. Features such as low-E coatings, argon gas fills, and triple-pane glass can significantly reduce energy bills while improving overall indoor comfort. Compared to older single pane windows, these modern options offer superior insulation, greater energy savings, and better noise reduction.

Fact: Energy Star certified windows can cut heating and cooling costs by up to 40% in commercial spaces.

Return on Investment (ROI)

Modern window options, especially energy-efficient ones, not only slash utility costs but also increase property value. For example, properties that undergo thoughtful window upgrades often see a 10-15% boost in their market worth.

Design Compatibility

Maintaining a sense of historical or architectural continuity is vital. Consider window styles that align with the existing exterior or interior space, particularly for older buildings and historic sites.

Employee and Customer Well-Being

Natural light from thoughtfully placed windows enhances employee productivity and customer satisfaction. Specific window types, such as floor-to-ceiling or specialty windows, can further improve the comfort, aesthetics, and functionality of a building’s interior living space. Improved air circulation also leads to better indoor air quality, nurturing healthier and happier occupants.

Window Installation and Maintenance

Proper installation is essential to ensure that commercial windows deliver on their promises of energy efficiency, safety, and long-term durability. Professional installation is highly recommended, as it helps prevent common issues like air leakage and water intrusion, which can compromise both the performance and lifespan of your windows. A well-installed window system not only improves energy efficiency but also enhances security and occupant comfort.

Regular maintenance is key to keeping your commercial windows in top condition. This includes routine cleaning of glass panes, lubricating hinges and moving parts, and inspecting window frames for signs of wear or damage. The maintenance requirements can vary depending on the window frame material—vinyl frames are generally low maintenance, while wood may require periodic sealing or painting, and aluminum frames benefit from regular checks for corrosion.

Choosing energy efficient options, such as Energy Star certified windows, can significantly reduce energy consumption and utility costs. These windows are rigorously tested and rated by organizations like the National Fenestration Rating Council (NFRC), providing building owners with reliable information on performance factors such as insulation, solar heat gain, and air leakage.

Installation costs for commercial windows can vary based on the window type, size, material, and the complexity of the project. While initial investment may be higher for advanced or custom solutions, the long-term savings in energy and maintenance often justify the expense. Enhanced security features, such as laminated glass and robust locking systems, can also be incorporated to protect your property and occupants.

Whether you’re planning a new window project or considering replacement windows to improve energy efficiency and comfort, a well-designed and professionally installed window system will provide good ventilation, abundant natural light, and a lasting boost to your building’s aesthetic appeal.
