Skylights in commercial buildings offer far more than just natural illumination. They create vibrant, energizing spaces that can boost productivity, enhance well-being, and even speed patient recovery in healthcare settings.

Modern skylight systems integrate with smart building technologies, optimizing energy efficiency and comfort. They can improve acoustics, aid in wayfinding, and serve as unique marketing features.

Let’s dive into the pros and cons of the six different skylight shapes:

Ridge Skylights

A Ridgelite also known as a Ridgelight, back-to-back or two-sided skylight is a type of skylight that features a common ridge, or apex, and two sides. These skylights create opportunities for long continuous runs for maximum light penetration. The triangular shape provides excellent strength and flexibility. In flat roof applications Ridgelites will have gable ends also known as ends lights which can be glazed with glass or architectural panels.

Pros:

• Ridge skylights provide extensive natural light running long distances
• Ideal for large open spaces
• Ridge lights can create a dramatic architectural feature

Cons:

• May require additional structural support when they are covering a wide expanse
• Potentially more complex installation and maintenance depending on size

Pyramid Skylights

Pyramid skylights draw inspiration from a timeless architectural form that has been utilized for over 4,500 years. Characterized by their four sloping sides that converge at a single point, these skylights create a striking four-sided, triangular appearance. Pyramid skylights not only enhance the aesthetic appeal of a building but also allow for abundant natural light, reducing the need for artificial lighting and contributing to energy efficiency. Their design ensures an even distribution of light, creating bright and inviting interior spaces.

Pros:

• The unique design collects and distributes light 360 degrees
• The design is aesthetically appealing
• The shape makes it ideal for shedding water and debris

Cons:

• Because of the many segments, they provide even light distribution

Cons:

• Polygons are more complex and require a more costly installation
• May require custom manufacturing to fit the final design and desired location
• The multiple facets make maintenance and cleaning challenging

Unit Skylights

A unit skylight, as the name suggests, is a single skylight typically featuring a single glazing plane.  While unit skylights can have a domed shape, flat skylights often glaze with insulated glass units or multiwall polycarbonate. Architects often incorporate multiple unit skylights into their overall design and lighting plans to enhance natural light and improve energy efficiency.

Pros:

• Versatile, they can be installed in different configurations or patterns
• They are often more affordable than custom-designed skylights
• Because there is only one panel and fewer parts, they are easier to maintain and repair

Cons:

• They lack the visual impact of larger skylight systems
• More skylights are required for larger spaces
• Skylight units provide only a limited amount of natural light.

Single Slope Skylights

Sometimes referred to as single pitch or lean-to skylights. While it may seem like these are unit skylights, single slope skylights are made up of several panels of dual-pane glazing, typically with insulated glass or multiwall polycarbonate. These skylights can be placed directly on a curb with a sloped pitch structure or built onto a parapet wall in flat roof applications.

Pros:

• These skylights have a simple, cost-effective design
• Easy to integrate into the existing slope or flat roof structures
• The slope causes water to run right off

Cons:

• Because there isn’t much artistry, they are less dramatic than other styles
• The single angle of light into the building is less than multi-faceted designs
• Limited spans without substructure

Barrel Skylights

Barrel vault skylights, also known as barrel-vaulted skylights, are an elegant and functional architectural feature that support large, curved glass pieces. These skylights create a stunning visual impact in a variety of applications, providing an abundance of natural light while enhancing a building’s aesthetic appeal.

Pros:

• The barrel shape provides even light distribution
• The shape is a distinctive architectural feature
• Because of the shape, they are effective at shedding water and snow

Cons:

• The curved shape is a more complex installation compared to flat skylights
• Custom manufacturing is required for both the framework and the curved glass
• Limited in size in glass applications

How to choose the right skylight for your project

After considering the pros and cons of various skylight shapes, it’s important to evaluate several key factors when selecting the ideal skylight for a commercial project.  This is a list of considerations.

A few unique benefits of skylights

Skylights are more than just windows on your roof, they can be game-changers for commercial spaces, offering perks that go way beyond letting in some extra sunshine. We’ve picked out five unique benefits that might surprise you about these overhead wonders. Here’s why skylights are secretly the MVPs of building design:

• Biophilic design: Skylights help incorporate natural elements into the built environment, supporting biophilic design principles. This connection to nature can improve occupant well-being and satisfaction. One study found that biophilic design can increase productivity by 6% and creativity by up to 15%.
• Seasonal affective disorder (SAD) prevention: Increased exposure to natural light can help mitigate the effects of SAD, particularly in regions with long, dark winters. Skylights can provide a crucial source of natural light during shorter days, helping to regulate circadian rhythms and boost mood for building occupants.  This is especially beneficial in senior living facilities where residents don’t go outside often.
• Potential for integration with smart building systems: Modern skylights can be integrated with automated shading and lighting control systems, optimizing energy efficiency and occupant comfort. This integration allows for dynamic adjustment of natural light levels throughout the day, working in tandem with artificial lighting to maintain ideal illumination while maximizing energy savings.
• Enhanced wayfinding: In large commercial spaces, skylights can serve as natural landmarks, aiding in navigation and creating a sense of orientation for occupants. By providing visual reference points and creating distinct areas of light and shadow, skylights can help people intuitively understand and navigate complex building layouts.
• Potential for solar energy integration: Some advanced skylight systems can incorporate photovoltaic cells, generating clean energy while providing natural light. This dual functionality can contribute to a building’s sustainability goals, potentially offsetting energy costs while still delivering the benefits of natural illumination.

F.A.Q.

How do skylights impact indoor air quality and ventilation in commercial spaces? Are there options for skylights that can be opened or integrated with ventilation systems?

Skylights that include venting can positively impact indoor air quality. Venting options can be manual or automated based on temperature, weather, or time of day. These venting skylights can help improve air circulation, reduce humidity, and remove indoor pollutants. 

What are the typical lifespans of different types of commercial skylights, and what kind of warranty options are generally available?

The lifespan of commercial skylights typically ranges from 20 to 40 years, depending on the materials used, quality of installation, and maintenance.

How do skylights affect the acoustic properties of a space, especially in large commercial buildings like offices or schools?

Skylights can help absorb and diffuse sound.  They can reduce the echo in large spaces.  The height of a skylight can improve sound distribution.  On the other hand,  the hard surfaces of skylights can reflect the sound and potentially increase noise levels. And, of course, rain or hail hitting the skylights will create noise.  Skylights can be designed with laminated glass that has a sound-dampening quality. 

Are there any specific considerations or specialized skylight options for unique commercial environments such as museums, greenhouses, or indoor sports facilities?

Specialized environments often require custom skylight solutions like museums which must protect the artwork.  Skylights can be made using UV-filtering glass or light control.  Greenhouses benefit from skylights that maximize light transmission while managing heat.  Indoor sports facilities require impact-resistant skylights and use shatter-resistant materials.

Are there any emerging technologies or materials in skylight design that are expected to revolutionize the industry in the near future?

We are now offering an option to integrate solar energy panels in the panes of glass. These panels can provide electricity to fans or lights installed with the skylight.

Other innovations on the rise include electrochromic glass which allows skylights to change opacity electronically, adjusting light transmission and heat gain without the need for shades.  Another innovation is photochromic and thermochromic materials that react to light or heat respectively, automatically adjusting their tint to optimize indoor comfort.

Are skylights weatherproof?

The quick answer: Yes! VELUX skylights are engineered with three layers of water protection and backed by an industry-leading 10-year installation warranty.

In the mid- to late-20th century, skylights were mostly made of plastic and called “bubble skylights.” This plastic was susceptible to damage from UV rays and normal weather conditions, leading the bubble skylights to become brittle and deteriorate, often resulting in water leaks.

After more than 75 years in the industry, VELUX has continued to enhance our skylight technology and durability creating our standard safety glass and three patented water protection layers. Depending on the type of skylight, these three layers include a gasket or deck seal, adhesive underlayment for secondary water protection, and engineered flashing for easy installation and primary water protection.

VELUX “Fresh Air” Skylights come equipped with rain sensors to automatically close the skylight at the first sign of rain, giving you peace of mind when the weather takes a turn for the worst. 

How strong are skylights?

Cutting a hole in your roof to install a skylight is a big deal! After all, when it comes to skylights, the glass is the pièce de résistance. You want to make sure it holds strong up there on the roof. That's why we offer a variety of glass options designed for strength and safety so you can rest assured the VELUX skylight you install will keep your home safe below.

Laminated Glass: This glass is cleaner, quieter, and safer than any skylight glass on the market today. That's why it comes standard on our deck- and curb-mounted skylights. As laminated glass, our standard glass meets all the safety and compliance codes for out-of-reach applications and includes a 10-year Hail Breakage Warranty.

Impact Glass: Our toughest glass, Impact Glass is highly resistant to penetration from flying debris. If you live in areas prone to large storms, this glass meets the requirements for wind-borne debris protection of the International Building Code Commercial (IBC), International Residential Code (IRC), and the Florida Building Code .

Snowload Glass: If you live in an area prone to heavy snowfall, Snowload Glass is the option for you. This glass is reinforced to support the added weight from accumulated snow on the skylight. And, as with every VELUX skylight, it is built to prevent leakage of any kind.

Note: The type of glass in your skylight will depend on the requirements of your city’s building codes.

Do skylights make a space hotter?

Climate control in a space with skylights can be a big worry, whether your primary concern is heat gain during the summer or heat loss during winter. That is why VELUX products are Energy Star qualified in all 50 states. Additionally, our glass skylights are tested for heat loss, heat gain, and light transmittance and then certified by the National Fenestration Rating Council (NFRC) to ensure quality performance.

VELUX skylights can also be paired with skylight shades! Skylight shades offer additional insulation to help mitigate heat loss and gain while giving you control over the amount of light you let into your space.

How do I know what skylight size I need?

Your skylight installer will help you determine what size skylights will best fit your home. The industry standard for a new, in-home skylight is typically 5% of the floor space in rooms with a lot of windows already and 15% of the floor space in rooms without much natural light. These ratios help keep your space as energy efficient as possible while enabling you to enjoy the sunshine and fresh air that skylights offer.

What glass comes standard in VELUX skylights?

Energy-efficient LoE3-366® glass is the standard for VELUX skylights, a far superior glass to the acrylic skylights of yesteryear. We call this our Standard Safety Glass due to its ability to whisk away rainwater and debris to stay clean and high-tech insulation that helps block unwanted outside noise. And with their energy efficiency and durability, glass skylights do not change color over time and, when installed properly, won’t leak or allow drafts.

What glass options are available for skylights?

Depending on your location, you may need specific glass to handle the harsh weather or abide by stringent building codes. That’s why VELUX offers Impact, White Laminated, Snowload, Tempered, and our patented Standard Safety Glass to fit the needs of any homeowner. Whether you’re out on the snow-capped Rockies, the windswept plains of the Midwest, or are alternating between sunny beach days and hurricane warnings along the Gulf Coast, we’ve got the glass to keep your skylight standing strong.

What is the standard finish or  exterior color of a skylight?

VELUX skylights feature a neutral gray color as a standard finish that blends well with most roofing materials. We also offer copper cladding upon request for select deck-mounted skylights and select roof windows. Your VELUX installer can answer more questions about the best look for your roof line.

Can I pick a different exterior color or finish?

With the exception of copper cladding for select deck-mounted skylights, VELUX SkyMax is the only skylight available with customized exterior colors and finishes. For all other skylights, the standard color or finish is neutral gray. But don't worry: neutral gray blends well with most roofing materials!
Want to control the amount of light coming in through your skylight? Easy: add a shade!

VELUX skylight shades allow you to not only control the amount of daylight coming in but also to boost the energy efficiency of your VELUX skylights. VELUX skylight shades can improve energy efficiency by up to 45% depending on the type of shades. Skylight shades can be pre-installed with your skylight or add the shades in minutes with the VELUX bracket system.

VELUX offers two types of skylight shades: Room Darkening and Light Filtering in solar operation so you can mix and match the amount of daylight you want in each room. And with over 100 colors and patterns, pre-installed or special ordered, you can personalize any space!

Deck-Mounted vs Curb-Mounted Skylights

VELUX skylights are available in deck-mounted and curb-mounted installation options. Deck-mounted skylights are nailed directly to your roof deck (the trusses and joists between the structural components of your roof). This gives them a lower profile on your roof and makes them ideal for new construction homes or new skylight cut-ins.

Curb-mounted skylights are more common on low-sloped roofs. They're installed on a curb or frame, usually made of two-by-fours, that your installer attaches to the roof. The skylight itself is then attached to the top of the curb. Think of curb-mounted skylights like a shoebox: the curb is the box and the skylight is the lid.
Choosing to work with a professional for your skylight journey involves a skylight installer or general roofer to come to your home and work with you on design, planning, and pricing. Ideally, the installer will have your desired skylight in stock and can quickly install it. Otherwise, they will have to order it from the manufacturer.

To DIY your skylight installation, you’ll need to buy your skylight through an authorized dealer such as Lowes, Home Depot, or other home improvement store. Typically, authorized dealers are staffed by knowledgeable employees that can help you answer any questions you have on the installation process. For VELUX skylights, you’ll also need to make sure to install them with VELUX flashing to ensure warranty coverage.
