How To Block Heat From A Skylight

Understanding the Issue with Skylight Heat

Skylights can transform any space, bringing in natural light and offering a glimpse of the sky. However, they often come with a downside – unwanted heat. Especially during the summer months, a skylight can act like a magnifying glass, concentrating solar heat into your living spaces. This issue is not just an inconvenience; it can substantially impact your indoor comfort and shoot up your energy bills. Let’s learn how to block heat from a skylight.

Benefits of Controlling Skylight Heat

Taking control of the heat from skylights can dramatically improve your quality of life. Firstly, you’ll enhance your comfort levels. No one likes to sit in a room that feels like an oven, right? Secondly, you’re doing your wallet a favor. By blocking the unwanted heat, you can cut down on air conditioning costs, making your home more energy efficient. This is also an excellent way to contribute to environmental conservation.

Type and Material of the Skylight Fixture

The type of glass and material used in your skylight windows play a significant role in the amount of heat they let in. Traditional glass may allow too much heat, whereas specialized glazing can help block heat effectively. It’s crucial to identify if your skylight is a culprit in raising your home’s temperature. If you’re unsure, local window experts can evaluate your fixture’s energy efficiency.

Sun Exposure and Skylight Positioning

The angle and positioning of your skylight also affect how much heat and light enter your home. For instance, a skylight facing the sun’s path will obviously capture more solar heat. Additionally, the time of the year can influence the high-angled glare and heat gain. Understanding these factors will guide you in choosing the right window treatment for your skylight.

Skylight Shades for Reducing Heat

Methods to Reduce Heat

Using Skylight Shades and Blinds

Blinds and shades offer a straightforward way to cover skylights and control the amount of light and heat entering your home. Cellular shades, for instance, have air pockets that act as insulators, helping to prevent heat loss in winter months and block the heat in summer. Pleated shades and thermal blinds are also effective options. When covering a skylight, it’s essential to choose shades or blinds that allow you to maintain a balance—blocking unwanted heat without limiting their functionality.

Applying Reflective Films

Window tinting with reflective or UV reflective films is another great strategy to cut the heat. These films work by reflecting the sun’s rays, reducing glare, and stopping a significant portion of heat from entering your home. When choosing the right window film, consider the type that blocks solar heat without overly darkening the room. Choosing the wrong skylight tint can cause larger problems. Installation is usually straightforward, but for best results, you might want to get in touch with professionals.

Installing Ventilation Systems

Ventilation is a natural way to bring balance to your indoor climate. Skylights with built-in vents can allow hot air to escape, reducing the likelihood of overheating. There are various options for ventilating skylights, from manual to motorized systems. If you’re interested in a high-tech solution, remote control systems offer the ultimate convenience. However you choose to ventilate, ensure your system is energy efficient to keep heating bills low.

Incorporating Heat Resistant Glazing

Glazing is not just for aesthetics; it also plays a critical role in controlling heat gain and loss. Heat-resistant glazing materials can block a significant amount of heat from entering your home. These specialized coatings also let in natural light without the unwanted cold or heat. If your skylights don’t yet have this feature, retrofitting is an option. Just consult with a professional to determine the most effective way to block heat while preserving the view of the sky.

Venting Skylight for Heat Escape

Utilizing External Shading Devices

External shading solutions like awnings, louvers, and other systems offer an extensive range of options for blocking sunlight. These devices are not only functional but provide enhanced aesthetic appeal. They can be retractable, allowing you to control the amount of light and heat that enters your home. When selecting an external shading device, consider its durability and ease of operation. Some even come in several designs and colors, letting you match them with your home’s exterior.

Adjusting Landscaping

Believe it or not, the trees and shrubs around your home can act as natural skylight covers. By strategically planting trees that will grow to block the sun’s rays, you can create a tasteful, ambient atmosphere inside. This method is particularly useful during the summer months, when you need to cut down on both heat and glare. Just remember that maintaining your green canopy will require planning and regular upkeep.

Integrating Smart Technology

In today’s world, smart technology offers more than just convenience; it’s also a practical way to manage light control and energy costs. Smart blinds and shading solutions can be integrated with home automation systems, giving you the power to adjust settings through a smartphone or voice commands. With motorized blinds and shades, you can even schedule when you want to block the light or let in natural light into your home, making it an all-year-round solution.


Skylights are a beautiful addition to any home, bringing in much-needed natural light and offering a stunning view of the sky. Although skylights are also sources of unwanted heat and glare, various methods can help you manage these issues effectively. From shades and blinds to specialized glazing and smart technology, the right window covering can provide a balanced indoor climate without sacrificing the beauty and functionality of your skylights.

Whether you’re battling the heat of the summer months or trying to prevent heat loss in the colder seasons, these tips offer ways of covering your skylights to meet your specific needs. Remember, choosing the right solution can be tricky because of its design, but with a little research and consultation, you can find an option that’s both stylish and functional.
