Skylights | Rooflights
Skylights are architectural features that allow natural light into a building through a window or a translucent panel installed in the roof or ceiling. They are designed to improve the energy efficiency of a building by reducing the need for artificial lighting during the day. Skylights can be made from a variety of materials, including glass, acrylic, and polycarbonate, and can be installed in a variety of structures, from homes to commercial buildings to greenhouses. Skylights can also be designed to filter out harmful UV radiation while allowing certain wavelengths of natural light to pass through, making them a popular choice for sustainable and environmentally conscious architecture.
Skylights have been used in architecture for centuries. In ancient Roman architecture, atriums and courtyards were often open to the sky, allowing natural light to illuminate the interior of buildings. During the Renaissance, skylights became more common in buildings such as churches and palaces. In the 19th century, the Industrial Revolution led to advances in glass manufacturing, making skylights more affordable and practical. Modern skylights can be found in a variety of structures, from homes to commercial buildings to greenhouses, and can be made from a variety of materials, including glass, acrylic, and polycarbonate.
Skylights improve sustainability by reducing the need for artificial lighting during the day, which in turn reduces energy consumption and lowers greenhouse gas emissions associated with electricity generation. By providing natural light, skylights can also improve the overall health and well-being of building occupants, as exposure to natural light has been linked to improved mood, productivity, and sleep quality. Additionally, skylights can be designed to filter out harmful UV radiation while allowing certain wavelengths of natural light to pass through, creating a more comfortable and energy-efficient indoor environment.
Skylight leakage can be caused by a variety of factors, including improper installation, age-related wear and tear, damage from severe weather, and structural issues. Poorly installed or damaged flashing around the skylight can allow water to seep through, while cracks or gaps in the skylight itself can also cause leakage. In addition, if the roof surrounding the skylight is damaged or deteriorating, water can penetrate the roof and leak through the skylight.
The ideal type of glass for a skylight depends on the specific needs and preferences, such as energy efficiency, safety, and durability. Low-E (low emissivity) glass is a commonly preferred option for skylights as it helps reduce heat transfer and blocks harmful UV radiation. Tempered glass is another popular choice since it's stronger and more impact-resistant than regular glass, making it a safer option. Laminated glass that contains multiple layers of glass and a plastic interlayer offers additional safety and sound insulation, making it suitable for high-traffic areas or noisy environments.
