Sun Tunnel vs. Skylight: Which Best Brightens Your Home? 

April 29, 2022

When it comes to enhancing natural light in your home, the choice often comes down to sun tunnels and skylights. Both options offer unique benefits and can transform a dimly lit space into a vibrant, inviting environment. However, understanding the differences between these two solutions is essential for making an informed decision.

Sun tunnels, known for their compact design and efficiency, contrast sharply with the larger, more open skylights. In this blog, we will explore the key differences between sun tunnels and skylights, helping you make an informed decision about which option best suits your home and lifestyle.  

What are Sun Tunnels?

Sun tunnels, also known as tubular daylighting devices (TDDs), are innovative structures designed to capture sunlight from the roof and funnel it into interior spaces. They consist of a rooftop dome, a reflective tube, and a diffuser that disperses the natural light evenly into the room. Sun tunnels are particularly useful in spaces where traditional windows or skylights are impractical or impossible to install.

How Sun Tunnels Work

Sun tunnels utilize advanced reflective materials to maximize the amount of sunlight they capture. The rooftop dome acts as a light collector, capturing daylight from various angles throughout the day. The sunlight is then directed down the reflective tube and diffused into the room through the diffuser, providing a soft, natural glow.

Advantages of Sun Tunnels

  • Energy Efficiency: Sun tunnels require no electricity to function, making them an eco-friendly and cost-effective lighting solution.
  • Daylight Quality: The diffused light from sun tunnels closely resembles natural daylight, creating a warm and inviting ambiance.
  • Flexibility: Sun tunnels can be installed in tight or awkward spaces, providing light in areas where skylights might not be feasible.

What are Skylights?

Definition and Purpose

Skylights are windows installed on the roof or ceiling of a building to allow direct sunlight into the interior spaces below. They come in various shapes and sizes, offering different design options to suit architectural preferences and lighting requirements.

Types of Skylights

  • Fixed Skylights: These skylights are stationary and cannot be opened. They provide a constant source of natural light but lack ventilation.
  • Vented Skylights: Vented skylights can be opened, allowing fresh air to circulate while also providing natural light. They are ideal for areas that require ventilation, such as kitchens or bathrooms.
  • Tubular Skylights: Similar to sun tunnels, tubular skylights capture sunlight through a rooftop dome and direct it into interior spaces through a reflective tube.

Advantages of Skylights

  • Abundant Natural Light: Skylights offer a direct path for sunlight to enter the room, illuminating the space and reducing the need for artificial lighting.
  • Ventilation Options: Vented skylights provide an additional benefit of improved airflow and can help with passive cooling in hot weather.
  • Aesthetics: Skylights can enhance the aesthetics of a room, adding a sense of openness and spaciousness.

What is the Difference Between Skylights and Sun Tunnels?

Both are roof penetrations that allow for light into your home. Skylights are larger and take longer to install; their installation involves two large holes in your roof and ceiling. Sun tunnels are a much smaller footprint on your home, but they also provide much less light. Also, it’s worth keeping in mind that there are two different types of skylights and sun tunnels. 

Skylights are either fixed or vented. Fixed are sealed to your roof, while vented let in fresh air along with natural light. Sun tunnels are either flexible or rigid; this really only has to do with their installation and not their performance. Fixed sun tunnels are used if a straight shot from the ceiling to the roof is possible, while flexible is used if there is some obstruction in the way. 

How Do Installation Costs Compare: Skylight vs. Sun Tunnel?

Installation Process for Skylights

The installation process for skylights begins with careful planning and measurement. Once the location is determined, a frame is created where the skylight is attached securely to the roof structure.

After ensuring proper sealing, the finishing touches are added, allowing the skylights open to provide natural light and ventilation effectively.

Cost of Installing Sun Tunnels

The cost of installing sun tunnels varies depending on factors such as location, materials, and installation complexity. Generally, homeowners can expect to spend between $500 and $2,500. This price includes both the tunnel and professional installation fees, ensuring optimal performance and aesthetic appeal.

Additional expenses may arise for roofing modifications or accessories like solar-powered fans. However, the long-term benefits of natural lighting and reduced energy costs often outweigh the initial investment.

Factors Affecting Installation Costs

Installation costs can vary significantly due to several key factors. One major factor is the complexity of the project, which can increase labor time and material requirements. Additionally, location plays a crucial role, as remote areas may incur higher transportation costs.

Another important aspect is the type of materials used; premium materials typically lead to higher expenses. Lastly, the experience of the contractor can impact costs, as skilled professionals may charge more for their expertise.

Which is easiest to install? 

As mentioned earlier, sun tunnels are easier to install. This is because you only need to cut two relatively small holes in your roof and fit a premade tube into those holes. From there, an acrylic dome is sealed onto your roof and a light diffuser to place on your ceiling. A skylight, however, needs two large holes in your ceiling and roof that will be unique to your home and will need to be refinished by a painter once the job is done. This is why a sun tunnel will take two professionals about 3 hours to complete, while skylights could take as long as a week. 

Which lets more light in?

Consider a skylight as a window incorporated into your ceiling, whereas a sun tunnel functions more like a reflective tube that captures sunlight. In simple terms, a skylight will permit significantly more light to enter. This is why skylights are the favored option if you aim to brighten a dim space in your house.

Skylight vs. Sun Tunnel: Which One is Right for You?

Considerations for Choosing Sun Tunnels

  • The location and orientation of your home: If your home receives limited direct sunlight, sun tunnels can efficiently capture and distribute it.
  • Energy efficiency: If reducing energy consumption is a priority, sun tunnels are an ideal choice.
  • Budget: If you have budget constraints but still want to enhance natural lighting, sun tunnels offer a cost-effective solution.

Considerations for Choosing Skylights

  • Aesthetics: Skylights can be architectural focal points, adding beauty and value to your home.
  • Ventilation needs: If you require both natural light and airflow in a particular space, a vented skylight might be the right choice.
  • Home design and roof structure: Skylights require suitable roof angles and proper positioning, so your home's design will influence the feasibility of installation.

Where Can You Install Skylights and Sun Tunnels?

Best Locations for Skylights

When considering the best locations for skylights, the roof of your home is a prime spot to enhance natural light. For tighter spaces, solar tubes are an excellent alternative, as they resemble tunnels and are generally more budget-friendly. Ultimately, the choice for your home should focus on maximizing brightness.

Ideal Spaces for Sun Tunnels

Sun tunnels are an ideal choice for areas where natural light is needed but space is limited. Unlike traditional skylights, solar tubes are generally more budget-friendly, making them accessible for various projects.

These innovative solutions can brighten up hallways, closets, and bathrooms, providing an effective way to enhance interior spaces. A skylight lets in expansive views, while sun tunnels focus on maximizing light without compromising structural integrity.

Considerations for Roof and Ceiling Types

When selecting roof and ceiling types, light sources play a crucial role. Incorporating solar tubes and skylights can significantly enhance natural lighting while improving energy efficiency.

Moreover, for those on a tighter budget, tunnels are generally more budget-friendly options, allowing for adequate illumination without the higher costs associated with traditional windows.

Are Skylights Energy Efficient Compared to Sun Tunnels?

Understanding Energy Efficiency in Skylights

Understanding energy efficiency in skylights is crucial for optimizing natural light while minimizing heat loss. Proper installation and selection of materials can enhance insulation, reducing reliance on artificial lighting and heating. Additionally, integrating energy-efficient technologies, like low-emissivity glazing, can further improve performance and sustainability in residential and commercial spaces.

How Sun Tunnels Contribute to Energy Savings

Sun tunnels are innovative structures that harness natural light, significantly reducing the need for artificial lighting. By channeling sunlight into interior spaces, they create bright environments while minimizing energy consumption.

This reduction in reliance on electricity leads to lower utility bills and a smaller carbon footprint, contributing to overall energy savings.

Heat Gain and Natural Light Benefits

Natural light into your home significantly enhances your living space, creating a warm and inviting atmosphere. By maximizing daylight, you can reduce reliance on artificial lighting, leading to energy savings.

Additionally, a skylight is a good investment for increasing natural light, as it brings sunlight directly from above, brightening rooms and improving mood.

What Are the Maintenance Requirements for Skylights and Sun Tunnels?

Maintaining Your Skylight

Maintaining your skylight is essential for maximizing its benefits. When installing a skylight or a sun tunnel, it's crucial to consider factors like heat gain in the summer and the amount of light they bring into your home. A traditional skylight might let in much light, while solar tubes can be a more efficient option.

Choosing the right option between a skylight and a sun tunnel involves understanding the pros and cons. Sun tunnels are generally easier to install than a traditional skylight. However, both can effectively bring natural light into spaces like a hallway or a closet while enhancing your light fixture choices.

Furthermore, proper maintenance can help you avoid the issues that skylights aren’t immune to, such as leaks or damage to the roofing material. Utilizing solar tax credits for a new skylight or adding a skylight or sun tunnel can also be beneficial for energy efficiency and aesthetics. Always consult a skilled installer for optimal results.

Care and Maintenance for Sun Tunnels

Sun tunnels may be easier to install than a sun tunnel and are often more budget-friendly. They effectively bring light into the room, adding natural light to your home while reducing reliance on artificial lighting. Unlike traditional skylight installation, solar tubes focus on funneling natural light without the need for extensive modifications.

Although skylights come with ventilation options, skylights cannot always provide the same efficiency as sun tunnels. Understanding what's the difference helps homeowners choose wisely. A skylight is a window that lets light in, while sun tubes are designed to let light in through a reflective tube, maximizing benefits of natural light.

To ensure optimal performance, regular care and maintenance for sun tunnels is essential, especially during summer and heat loss seasons. Using a blind can help control brightness, while the installation of sun tunnels guarantees a flexible approach to adding more natural light to your space.

Common Issues and Solutions

Common issues in homes often include inadequate lighting and ventilation. Skylights can provide natural light and fresh air into your home. When choosing a skylight, consider whether a big skylight or a flexible sun is best suited for your space.

For more affordable options, installing a sun tunnel is a good alternative. Sun tunnels take a fraction of the cost of traditional skylights, making them a practical choice for bringing light to a room without creating a hole in the roof.

Understanding the difference between a skylight and a sun tunnel is essential. While rigid sun tunnels provide direct sunlight, they may not allow heat loss in the winter to be minimized as effectively as some skylights.

Ultimately, both options can help you effectively turn off the light during the day while ensuring your home is bright and airy. To complete the installation, consult with professionals for best results.

Choosing Between Sun tunnels vs Skylights 

If you want natural light in your home, it is better to get a skylight. Sun tunnels are great when you want sunlight in sections of your home that would not allow for a skylight. However, they do not provide the type of light that a skylight can. While they are more expensive and take longer to install, skylights simply work a lot better for what they have to do than a sun tunnel.IBEX Roof offers installation services and repairs for skylights and sun tunnels to improve natural lighting in homes around Vancouver and Portland.
