A skylight enhances a building’s appeal and functionality, making it a desirable choice for businesses and homeowners looking for budget-friendly ways to bring in more sunlight. Here is what contractors need to know about skylights.
Understanding the Purpose of a Skylight
Skylights serve multiple purposes, from improving natural light within a space to enhancing energy efficiency. By allowing more daylight to enter a room, skylights reduce our need for LED lighting, lowering energy bills and creating a more inviting atmosphere. Additionally, they can help regulate indoor temperatures and improve air quality.
Skylight Materials
You must ensure you pick the right materials to design durable skylights. The two primary materials for skylight glazing are glass and plastic (typically acrylic or polycarbonate).
Glass Skylights
Glass skylights are known for their superior clarity, durability, and resistance to UV radiation. They often feature multiple layers of tempered or laminated glass to enhance strength and safety. Glass skylights are more expensive than their plastic counterparts but offer better insulation properties and a longer lifespan.
Plastic Skylights
Plastic skylights, made from acrylic or polycarbonate, are lighter and more affordable. While they may not offer the same level of insulation as glass, they are highly impact-resistant and less prone to breaking, which is suitable for regions with extreme weather conditions. However, it’s worth noting that plastic skylights can become discolored or scratched over time.
Installation Methods and Tools for a Skylight
Knowing the proper methods and tools for installing a skylight is necessary—such as curb-mounted and deck-mounted installation.
Curb-Mounted Skylights
Curb-mounted skylights sit on a raised frame (or “curb”) attached to the roof. This method is suitable for roofs with a low slope, as the curb helps elevate the skylight above the roofline. Ensure the curb has insulation and cracks are sealed to prevent leaks.
Deck-Mounted Skylights
Deck-mounted skylights attach directly to the roof deck, providing a sleeker profile. This method is generally quicker to install but requires careful sealing around the edges to prevent water infiltration.
Tools and Tips
Basic Tools
Essential tools for any roofing project include a tape measure to ensure accurate measurements, a level to maintain a straight and even surface, a saw for cutting materials to size, roofing nails for secure attachment, and sealant to protect against water infiltration. Each tool helps contractors build a durable structure.
For Plexiglass
Use a drill bit specifically designed for plastic when working with plexiglass to prevent damage. Our most helpful tip for drilling into plexiglass is to steady your pressure while drilling to maintain control and overheating. This method is essential to know when working with a material such as plexiglass.
Sun Path and Season
Consider the sun’s path and seasonal changes when installing a skylight. Positioning skylights to maximize natural daylight during the winter months while minimizing excessive heat in the summer can greatly improve energy efficiency and comfort indoors.
With a solid understanding of what contractors need to know about skylights, you can confidently make better decisions during construction. Help your clients achieve energy efficiency and increase sunlight with this guide to understand skylights better.
