Skylights are openings in your roof that can allow sunlight to flood your attic, making it a livable space rather than just a storage unit. In addition, they are used to provide natural ventilation and light in many other instances such as stairwells, bathrooms and corridors. They can be made of glass or plastic of various qualities. They can also be operable or fixed.
Since they are openings in the roof, skylights can potentially allow heat to enter a space, depending on various factors. Here are some considerations regarding heat transfer through skylights:
Solar Heat Gain: Skylights, particularly those made of glass, can allow sunlight to enter the room. Sunlight carries heat, and this can contribute to increased solar heat gain within the space. The amount of heat gain depends on factors such as the orientation of the skylight, the glazing type (e.g., single pane, double pane, low-E coating), and any shading devices or treatments applied to the skylight.
Insulation and Glazing: The insulation properties and glazing technology of the skylight can impact its ability to resist heat transfer. Skylights with low-E (low-emissivity) coatings or multiple panes of glass filled with insulating gases can help reduce heat transfer and improve energy efficiency.
Ventilation and Airflow: Skylights that can be opened or have built-in ventilation features can provide an opportunity for passive cooling by allowing hot air to escape and encouraging natural airflow. This can help reduce heat buildup and improve comfort.
Shading and Glare Control: Utilizing shading devices such as blinds, shades, or films on skylights can help block or reduce direct sunlight, reducing heat gain and glare. These shading options can provide additional control over the amount of heat entering the space.
It’s important to strike a balance between maximizing natural light and managing heat gain when considering skylights. In warm climates or spaces with excessive heat gain, proper shading, glazing selection, and insulation can be essential to minimize heat transfer through skylights.
Consulting with professionals experienced in skylight installation and energy-efficient design can help you select the appropriate skylight type, glazing options, and shading devices based on your specific needs, climate conditions, and desired energy performance.
