A solar tube skylight is a device that brings natural light into indoor spaces. It consists of a dome-shaped collector, a reflective tube, and a diffuser. Solar tube skylights capture sunlight and direct it into a room through a small tube. They are also known as solar tubes, light tubes, or tubular skylights. These lighting solutions are energy-efficient and easy to install. Here are the different types of solar tube skylights:
Based on Size and Number:
Solar tube skylights come in different sizes to accommodate various amounts of natural light. There are also models designed to fit together in a row to provide even more illumination. The options typically include 10-inch tubes, which are suitable for small spaces like closets or bathrooms. The 14-inch tubes, which are ideal for medium-sized rooms such as kitchens or hallways. Finally, the 22-inch tubes, which are meant for larger areas like living rooms or offices.
Based on Installation:
Solar tube skylights are also classified according to how they are installed. There are two main types: flexible and rigid tubes. Flexible tubes are bendable, making them perfect for installations where the path to the ceiling is not straight due to obstacles like wires or beams. Rigid tubes, on the other hand, are straight and best used when there is a clear path from the roof to the ceiling.
Based on Ventilation:
Solar tube skylights can also be sorted by whether they open or stay closed. Non-ventilated types are permanently shut and are a great choice for areas that just need extra light. Ventilated solar tubes, however, have the ability to open and close like a window. This is perfect for rooms that require air circulation, too.
Based on Application:
These solar tube skylights are versatile and can be used in a variety of locations. There are specific types for different rooms in the house. For example, there are solar tubes for bathrooms, kitchens, living spaces, and hallways. Each of these is tailored to fit the unique needs of each room. Additionally, there are even commercial solar tube skylights designed specifically for offices, retail stores, and other business settings.
Based on Additional Features:
Finally, solar tube skylights can be classified according to any extra features they may have. Some come with built-in UV filters. These are important for protecting furniture and flooring from being damaged by the sun's ultraviolet rays. Others might have advanced tubing technology. This allows them to capture and distribute light more effectively, providing brighter and more illuminated room.
The solar tube skylight comprises various features that enhance its functionality. Here are the key features to highlight:
Reflective Tube
At the core of each solar tube skylight is a highly reflective tube, typically made of durable and weather-resistant materials like aluminum and polycarbonate. This tube serves as the conduit for sunlight, effectively capturing and channeling light from the roof to the interior space. The interior surface of the tube is coated with a reflective material, usually a silver or mylar coating, specifically designed to maximize light transmission. The tube is then sealed with a clear, UV-resistant dome at the top and a trim ring at the bottom, ensuring minimal light loss and preventing heat transfer.
Diffuser
The diffuser is a crucial component that ensures the even distribution of natural light within the room. Installed at the bottom of the solar tube, it comes in various designs, including flat, frosted, or prismatic, to meet specific lighting requirements. The diffuser is crafted from high-quality, translucent plastic or acrylic materials. It is designed to scatter and soften the beam of light transmitted through the tube, thus preventing harsh glares and hotspots. The light diffusion process not only enhances the ambient lighting but also contributes to the overall aesthetic appeal of the space.
Ventilation Kit
The Ventilation Kit is optional but significantly enhances the functionality of solar tube skylights. It comprises components such as a flexible duct, a solar-powered fan, and an electronic control system. The Ventilation Kit allows for the circulation of fresh air, thus improving indoor air quality. It helps in preventing condensation buildup and reduces the heat, contributing to a more comfortable living environment. Additionally, the Ventilation Kit is equipped with an electric control system that facilitates the opening and closing of the tube skylight, thereby enabling manual or automatic ventilation.
Crank Handle
The crank handle is primarily used to manually open and close the skylight. It is designed for hard-to-reach places and is easy to install and use. The crank handle system enhances the control of outdoor air and natural light. It is connected to an electric motor that opens and closes the skylight. The electric motor is powerful, reliable, and equipped with weatherproof housing. It can be used to operate multiple skylights simultaneously, and it offers the option for integration with home automation systems.
Solar tube skylights are small and versatile. They are used in various applications to bring natural light into indoor spaces. Here are some common usage scenarios:
Residential Lighting
Solar tube skylights are installed in residential areas. For instance, in hallways, living rooms, kitchens, and bathrooms. They brighten up these spaces. They reduce the need for artificial lighting during the day.
Dark Rooms
These are rooms that receive little or no natural light. Examples include interior rooms and spaces with no windows. Solar tube skylights provide natural light. They make these rooms more pleasant and usable.
Energy Efficiency
Energy-efficient buildings incorporate solar tube skylights. This is to maximize natural lighting. This reduces energy consumption and utility bills. Businesses and homeowners save money and benefit from this.
Commercial Spaces
These are small light wells that are installed in commercial buildings. For example, offices, retail stores, restaurants, and hotels. They create inviting and well-lit environments for customers and employees.
Workshops and Studios
Artists and craftsmen prefer natural light to work without shadows or glare. Solar tube skylights are a popular choice for workshops, art studios, and creative Spaces.
Health Facilities
These include hospitals, clinics, and nursing homes. Solar tube skylights are installed to improve lighting in patient and treatment rooms. Access to natural light has positive health benefits for patients and staff.
Educational Institutions
Schools, colleges, and universities use solar tube skylights. They brighten classrooms, libraries, and common areas. Natural light improves concentration and creates a better learning environment for students.
Retail and Display Areas
Skylights enhance the lighting in retail stores and display areas. This is for products and merchandise. They create attractive and well-lit shopping environments for customers.
Entryways and Hallways
Solar tube skylights can be installed in entryways and hallways. This is to ensure a well-lit and welcoming first impression for visitors and guests.
Consider the following factors before buying a solar tube skylight.
Location and Climate
Install solar tube skylights where natural light is needed most, like kitchens and living rooms. Also, consider the climate. A solar tube with a built-in air vent is ideal for warmer areas as it provides cooling options. In colder climates, choose a well-insulated model to prevent heat loss.
Tube Size and Length
Choose a size that balances light and space. Larger tubes give more light but need more ceiling space. If the area to be lit is small, a standard size tube will work. But if space is tight, consider a compact design. Tube length varies too; opt for a shorter tube if the building's roof is low. Alternatively, pick a longer tube to reach further if there are obstacles.
Diffuser Options
Solar tubes come with different diffusers. A frosted glass diffuser softens and spreads light evenly. A clear glass one maximizes brightness. For aesthetics, choose a decorative diffuser that suits the room's style.
Installation Considerations
Ensure there's a roof space for solar panels without blockages from trees or buildings. The tube must run straight from the roof to the ceiling for best performance. Sloped roofs may need special brackets for stability. Consider hiring a professional for precise and safe installation, especially on high or tricky spots.
Ventilation
Some skylights have built-in vents. They open manually or automatically to cool rooms and release hot air. This airflow improves comfort and reduces air conditioning needs.
