| Tubular Skylight | Consists of a dome-shaped exterior collector, a reflective tube, and a diffuser inside the room. It transmits light through a reflective tube, ideal for areas with limited roof access. | Excellent for areas with limited roof space, relatively inexpensive, easy installation. | Limited light diffusion, smaller aperture restricts the amount of light entering the room compared to larger skylights. |
| Flush Mount Skylight | Installed directly into the roofline, creating a seamless integration with the roof surface. They sit flush with the roof, offering a clean, modern aesthetic. | Sleek and modern appearance, improved curb appeal, often available in various sizes and shapes. | Can be more expensive than other types, installation requires precise measurements and expertise. |
Skylight Materials
The choice of materials significantly impacts the skylight’s performance, durability, and cost. Common materials include glass, plastic (polycarbonate or acrylic), and metal.
Glass skylights, typically made from tempered or laminated glass, offer excellent light transmission and durability. Tempered glass is stronger and safer than annealed glass, resisting breakage and shattering into smaller, less dangerous pieces. Laminated glass consists of multiple layers bonded together with a polyvinyl butyral (PVB) interlayer, providing enhanced safety and insulation. The use of Low-E coatings on glass further improves energy efficiency by reducing heat transfer.
Plastic skylights, often made from polycarbonate or acrylic, are lighter and more impact-resistant than glass, making them a suitable choice for areas prone to hail or high winds. Polycarbonate offers superior impact resistance compared to acrylic, while acrylic provides better clarity. However, plastic skylights generally have lower light transmission than glass and may degrade over time due to UV exposure.
Metal framing is commonly used in skylight construction to provide structural support and durability. Aluminum is a popular choice due to its lightweight yet robust nature and corrosion resistance. Steel is another option, offering even greater strength but at the cost of increased weight and susceptibility to corrosion if not properly treated. The selection of metal framing material depends on factors such as budget, aesthetic preferences, and the specific requirements of the skylight design.

Interior blinds, shades, and curtains offer varying degrees of light control, from sheer fabrics that diffuse light to blackout options that completely block it. Exterior shades provide superior solar heat gain reduction compared to interior coverings, as they intercept solar radiation before it reaches the glazing. The material composition of the covering significantly impacts its effectiveness. For example, reflective materials can reduce solar heat gain more effectively than absorptive materials. The color also plays a role; lighter colors reflect more light and heat, while darker colors absorb more.
Comparison of Skylight Ventilation Methods
Several ventilation methods are employed in skylights, each with its own advantages and limitations. Natural ventilation relies on pressure differences created by wind and temperature gradients to induce airflow. This method is passive and requires no external energy input, but its effectiveness depends on external weather conditions. Mechanical ventilation utilizes fans to actively exhaust or introduce air, providing more consistent and controllable airflow regardless of weather. Hybrid systems combine natural and mechanical ventilation to optimize both energy efficiency and ventilation performance. For example, a system might employ natural ventilation during favorable weather conditions and switch to mechanical ventilation when needed to maintain indoor air quality. The selection of the appropriate ventilation method depends on factors such as climate, building design, and occupant needs. In regions with consistent breezes, natural ventilation might suffice. In climates with little wind or high humidity, mechanical ventilation is often more effective in ensuring adequate air exchange.
