Tubular skylights, also known as solar tubes or sun tunnels, have gained popularity for their ability to bring natural daylight into interior spaces. These innovative light sources harness sunlight and distribute it through a reflective tube, brightening up even the most dimly lit areas of a building. If you're considering installing tubular skylight or already have them in place, this guide provides essential insights into their installation and maintenance, ensuring that your spaces continue to enjoy the benefits of abundant, energy-efficient natural light.

Understanding Tubular Skylights

Skylight System consists of three main components: a rooftop dome, a reflective tube, and a diffuser installed on the interior ceiling. The rooftop dome captures sunlight and directs it into the reflective tube. The reflective tube, often coated with a highly reflective material, efficiently transports the sunlight to the interior space. Finally, the diffuser spreads the natural light evenly throughout the room, providing illumination without the need for electricity.

Benefits of Tubular Skylights

Energy Efficiency: Tubular skylights provide ample natural light, reducing the need for artificial lighting during daylight hours. This leads to energy savings and a smaller environmental footprint.

Improved Mood and Well-Being: Natural light has been shown to positively impact mood, productivity, and overall well-being. Tubular skylights can create a more pleasant and inviting indoor environment.

Enhanced Aesthetics: The soft, diffused light from tubular skylights can enhance the aesthetic appeal of interior spaces, making them feel more open and spacious.

Cost Savings: By reducing the reliance on electric lighting, tubular skylights can lead to significant cost savings on energy bills over time.

Less Heat Gain: Tubular skylights distribute light without emitting excessive heat, as traditional skylights can. This helps maintain a comfortable indoor temperature.

Considerations for Tubular Skylight Installation

Room Placement: When deciding where to install a tubular skylight, consider the function of the room and its lighting needs. Rooms that are frequently occupied, such as kitchens, living rooms, and bathrooms, benefit the most from the natural light provided by the skylight.

Roof Angle: The angle of your roof can impact the efficiency of the skylight. Roofs that face north might receive less direct sunlight while south-facing roofs receive more consistent sunlight throughout the day.

Daylight Variations: Keep in mind that the amount of natural light entering through the skylight will vary based on the time of day and weather conditions. While tubular skylights are excellent for brightening up interior spaces, they might not completely replace the need for artificial lighting during evening hours.

Sun Tunnel Length: Longer reflective tubes might be necessary for installations in multi-story buildings or spaces that require more light. However, longer tubes can reduce light output. Consult with professionals to find the right balance for your specific needs.

Impact on Roofing: Tubular skylight installation involves cutting a hole in your roof. Ensure that your roofing material can accommodate this modification without compromising its integrity. Consult with a roofing professional to assess the impact on your roof.

Maintenance Best Practices

Regular Inspection: Periodically inspect the interior and exterior components of the tubular skylight. Check for any signs of damage, cracks, or discoloration that might affect its performance.

Clean the Dome: The rooftop dome is exposed to the elements and can accumulate dirt, leaves, and debris. Clean the dome to ensure maximum sunlight capture. Use a gentle cleanser and a soft cloth to avoid scratching the surface.

Dust the Diffuser: The interior diffuser can collect dust over time. Regularly dust the diffuser to maintain its light-spreading capabilities.

Clean Reflective Tube: If your skylight has a reflective tube, ensure it remains clean and free from obstructions. Use a long brush or specialized tool to gently clean the inside of the tube.

Check Seals and Flashing: Examine the seals and flashing around the skylight for signs of wear, cracks, or deterioration. These components are essential for preventing water infiltration.

Clear Condensation: In certain weather conditions, condensation might form on the interior of the skylight. This is usually temporary and should dissipate as conditions change.

Installation and Maintenance Benefits

Improved Indoor Environment: Tubular skylights enhance the indoor environment by providing even, natural illumination that reduces glare and shadows.

Health and Well-Being: Exposure to natural light has been linked to improved mood, productivity, and overall health. Tubular skylights bring these benefits to interior spaces.

Reduced Carbon Footprint: By relying more on natural light and less on electric lighting, tubular skylights contribute to energy savings and reduce greenhouse gas emissions.

Daylight Harvesting: Tubular skylights are a form of daylight harvesting, which involves harnessing and utilizing natural light to reduce energy consumption.

Enhanced Aesthetics: The soft, diffused light from tubular skylights can enhance the aesthetic appeal of your interior spaces, making them more inviting and visually pleasing.

Cost Savings: Over time, the energy savings from reduced electric lighting usage can lead to significant cost savings on utility bills.

In Conclusion

Tubular skylights bring the beauty and benefits of natural light into interior spaces, creating inviting, well-lit environments while minimizing energy consumption. By following installation and maintenance tips, you can ensure that your tubular skylights remain efficient, effective, and contribute to a healthier, more sustainable living or working space. Whether you're looking to brighten up a dark room or enhance the overall aesthetics of your building, tubular skylights offer an innovative solution that brings the outdoors in.
