Tube skylights vs traditional skylights: Navigating the light-filled choice

The debate between tube skylights and traditional skylights has become increasingly relevant in the quest for brightening interior spaces with natural light. Both options have their unique characteristics, advantages, and considerations. This article explores the differences between tube skylights and traditional skylights, helping you make an informed decision based on your specific needs and preferences.

Understanding tube skylights

Tube skylights, also known as solar tubes or sun tunnels, represent a modern and innovative approach to channelling natural light into interior spaces. These cylindrical devices consist of a dome or light-capturing unit installed on the roof, a reflective tube that directs sunlight, and a diffuser or lens that disperses the light evenly within the room. Tube skylights are particularly popular in areas where traditional skylights may not be feasible due to limited roof space or structural constraints.

Advantages of tube skylights

  • Installation flexibility: Tube skylights offer greater flexibility in terms of installation. Their compact design allows them to be installed in spaces where traditional skylights may not fit, such as narrow hallways, closets, or bathrooms. This adaptability makes tube skylights an excellent choice for bringing natural light to interior areas that are typically challenging to illuminate.
  • Reduced heat transfer: The tube design of tube skylights helps minimise heat transfer, making them more energy-efficient than traditional skylights. Many tube skylights feature advanced glazing and insulation options that further contribute to thermal performance, allowing for the entry of natural light without compromising the indoor climate.
  • Cost-effective solution: In terms of cost, tube skylights are often more budget-friendly than their traditional counterparts. The simplicity of their design and installation process contributes to a lower overall cost, making them an attractive option for those seeking an economical way to introduce natural light into their homes or commercial spaces.
  • Less prone to leaks: The sealed and streamlined design of tube skylights makes them less prone to leaks than traditional skylights. Their compact size and minimal penetration through the roof reduce the risk of water ingress, offering a reliable solution for areas with challenging weather conditions.

Understanding traditional skylights

Traditional skylights, often referred to as roof windows or ceiling windows, are fixtures installed directly into the roof of a building. They come in various shapes, including fixed, vented, or operable designs, and are typically larger than tube skylights. Traditional skylights have been popular for centuries, adding a touch of timeless elegance to architectural designs.

Advantages of traditional skylights

  • More extensive light coverage: One of the primary advantages of traditional skylights is their ability to provide larger light coverage. Their expansive size allows more sunlight to enter the space, making them ideal for rooms with high ceilings or areas requiring a significant amount of natural light.

  • Enhanced ventilation: Many traditional skylights come with ventilation options, allowing for the entry of fresh air in addition to natural light. This feature is particularly beneficial in areas such as kitchens and bathrooms, where proper ventilation is essential for comfort and well-being.

  • Architectural aesthetics: Traditional skylights contribute to the architectural aesthetics of a building, adding a sense of openness and sophistication. Their larger size and various design options make them a visually striking element that complements the overall design and ambience of the space.

  • Operability and control: Unlike tube skylights, many traditional skylights are operable, allowing occupants to control the amount of light and ventilation. Some models come with remote-controlled or automated features, allowing for easy adjustment based on changing preferences or weather conditions.

Decision-making factors

Space and structural considerations: The layout and structure of your building play a crucial role in determining whether skylights or traditional skylights are more suitable. Tube skylights offer flexibility in tight spaces, while traditional skylights may be preferred for areas with ample roof space and higher ceilings.


Lighting requirements: Consider the specific lighting requirements of the interior space. Traditional skylights may be more suitable if you need to flood a larger area with natural light. Tube skylights provide a focused and efficient solution for smaller or challenging spaces.


Energy efficiency goals:
If energy efficiency is a priority, both skylights and traditional skylights can contribute positively. However, tube skylights are often lauded for their reduced heat transfer and cost-effectiveness, making them a compelling choice for those aiming to minimise their environmental footprint.


Budget constraints: Your budget considerations will also influence the choice between tube skylights and traditional skylights. Tube skylights generally offer a more economical solution, making them appealing to those seeking a cost-effective way to introduce natural light into their spaces.
