Sun Tunnels (Solar Tubes)

Sun tunnels, also known as solar tubes, tubular skylights, or light pipes, are innovative natural lighting systems designed to bring daylight from the rooftop into interior spaces where traditional windows are not practical. Unlike conventional skylights that require large roof openings and may introduce excessive heat gain, sun tunnels use a compact optical design to capture and transfer natural sunlight efficiently into areas such as hallways, bathrooms, storage rooms, and walk-in closets. A complete sun tunnel system consists of three main components, starting with the rooftop capture dome, which is made from durable weather-resistant acrylic or polycarbonate material and collects sunlight from different angles. Advanced models include optical prisms or light-directing lenses that improve daylight collection during morning, evening, and cloudy conditions. The second component is the highly reflective optical tube, which is constructed from aluminum and features a specialized internal reflective coating that allows sunlight to travel through the tunnel with minimal loss. This reflective design enables daylight to pass through long distances and around attic obstacles while maintaining strong illumination levels. Sun tunnels provide an energy-efficient lighting solution by reducing dependence on artificial lights during the daytime while maintaining a compact, low-maintenance, and weather-protected installation system.
