Difference Between A Sun Tunnel And Sky Light

When it comes to bringing natural light into your home, both sun tunnels and skylights offer unique benefits. However, they also have distinct differences that can impact your choice based on your specific needs and preferences. This guide explores the key differences between sun tunnels and skylights.

Overview

What is The Sun Tunnel?

Designed to capture and direct sunlight from the roof to a specific area inside the home through a reflective tube.
It is ideal for smaller spaces or areas where traditional skylights may not be feasible.

What is a Skylight?

Larger openings in the roof allow direct sunlight to enter the home.
Suitable for larger spaces where maximum natural light is desired.

Key Differences

Feature	Sun Tunnels	Skylights
Design	Circular, tubular	Rectangular, square, or custom shapes
Size	Typically smaller (10-14 inches in diameter)	Larger (up to several feet in length and width)
Installation	Easier and less invasive	More complex and may require structural modifications
Light Distribution	Diffused, more even light	Direct, can create bright spots
Energy Efficiency	Highly efficient due to smaller size	Varies based on size and type (double glazing, etc.)
Ventilation	No ventilation	Can be fixed or vented for air circulation
Cost	Generally less expensive	Can be more costly due to size and installation
Best Use	Small spaces, hallways, closets, bathrooms	Large rooms, living areas, kitchens, bedrooms

Installation And Maintenance

Sun Tunnels

Installation: Typically less invasive and can be installed in a few hours.
Maintenance: Minimal, mainly involves cleaning the dome and occasionally the reflective tube.

Skylights

Installation: Requires professional installation due to structural considerations. It may take several days depending on the complexity.
Maintenance: Regular cleaning of the glass and checking for leaks. Operable skylights may need more frequent maintenance.

Benefits And Drawbacks

Sun Tunnels

Benefits

Ease of Installation: Quick and less disruptive to your home.
Energy Efficiency: Smaller size reduces heat loss and gain.
Cost-Effective: Lower installation and maintenance costs.
Versatility: Fits in spaces where skylights can’t be installed.

Drawbacks

Limited Light Output: Not suitable for large spaces.
No Ventilation: This does not offer the option to ventilate the space.

Skylights

Benefits

Abundant Natural Light: Provides ample daylight, enhancing the aesthetics of a room.
Ventilation Options: Can improve indoor air quality if operable.
Design Flexibility: Various shapes, size and glazing options are available.

Drawbacks

Complex Installation: Requires more time and potential structural changes.
Higher Cost: More expensive to install and maintain.
Heat Gain/Loss: A larger surface area can impact energy efficiency.

Choosing The Right Option

When deciding between sun tunnels and skylights, consider the following factors:

Purpose And Space
- For small, confined spaces like hallways, closets or bathrooms - sun tunnels are ideal.
- For larger areas such as living rooms, kitchens or bedrooms - skylights provide better illumination and ventilation options.
Budget
- If budget constraints are significant, sun tunnels offer a cost-effective solution with minimal installation expenses.
- Skylights, though more costly, provide greater benefits in terms of light and ventilation for larger spaces.
Energy Efficiency
- Sun tunnels are more energy-efficient due to their smaller size and reduced heat transfer.
- Skylights can be energy-efficient if properly insulated and double-glazed.
Aesthetic Preferences
- Skylights enhance the architectural appeal of a room and provide expansive views of the sky.
- Sun tunnels are discreet and less noticeable, providing light without altering the room’s appearance significantly.
Ventilation Needs
- If improving ventilation is a priority, operable skylights are the better choice.
- Sun tunnels do not offer ventilation, making them suitable for areas where air circulation is not a concern.

Installation Process

Sun Tunnels

Site Assessment: Determine the best location on the roof and inside the home.
Cutting the Roof Opening: Create a small opening for the dome.
Installing the Dome: Secure the dome to the roof.
Running the Tube: Install the reflective tube from the dome to the interior ceiling.
Installing the Diffuser: Attach the diffuser to the ceiling to distribute light evenly.

Skylights

Site Assessment: Evaluate the roof structure and determine the best placement.
Cutting the Roof Opening: Create a larger opening to fit the skylight.
Installing the Skylight: Secure the skylight frame and glass to the roof.
Flashing and Sealing: Apply flashing to prevent leaks and seal the edges.
Interior Finishing: Finish the interior trim to blend with the ceiling.

Maintenance Tips

Sun Tunnels

Regular Cleaning: Clean the exterior dome periodically to remove debris.
Check Seals: Inspect and ensure seals are intact to prevent leaks.

Skylights

Glass Cleaning: Clean the glass regularly to maintain clarity.
Inspect for Leaks: Check the flashing and seals for any signs of leaks.
Operational Check: For operable skylights, ensure the opening mechanism works smoothly.

Conclusion

Both sun tunnels and skylights are excellent options for bringing natural light into your home, but the best choice depends on your specific needs, budget and preferences. Sun tunnels offer a cost-effective and efficient solution for small spaces, while skylights provide abundant light and ventilation for larger areas. By considering the factors outlined in this guide, you can make an informed decision that enhances your home's comfort and aesthetics.
