We’re always asked, “Do Skylights Open?” by many of our installation customers. In this article we’ll review the differences between skylights that open and ones that don’t open.

What is the Difference Between Vented and Non-Vented Skylights?

When it comes to brightening your living space, skylights can make a huge impact. However, not all skylights are created equal. There are mainly two types of skylights: vented and non-vented, also known as fixed skylights.

Fixed Skylights: These are the most straightforward type of skylight. Once installed in your roofline, they remain closed, allowing natural light to flood into your home without providing any ventilation. Fixed skylights are particularly useful for rooms like bathrooms where privacy is essential, but natural illumination is desired.

Vented Skylights: Unlike fixed skylights, vented skylights open and close, enabling airflow throughout your home. If you’re a homeowner looking to regulate hot air that naturally accumulates near the ceiling, vented skylights can help. They’re well-ventilated options, excellent for rooms prone to mold and mildew, like attics.

Whether you’re remodeling or just considering skylight installation for your home, understanding the main types of skylights can help you make an informed decision.

What are the Benefits of Vented Skylights? Do Venting Skylights Work?

Now that you know the basic difference between vented and non-vented skylights, you might be wondering about the advantages of choosing a vented option. Well, vented skylights offer a plethora of benefits that extend beyond mere aesthetics.

Natural Ventilation: One of the primary benefits of vented skylights is improved air circulation. As hot air rises, these skylights expel it from your living space, making the environment more comfortable.

Energy Efficiency: Believe it or not, vented skylights can be energy-efficient. By letting out hot air in the summer and allowing cooler air to circulate, you can actually reduce energy costs. Just make sure to choose a skylight with energy-efficient features like low-e laminated glass.

Control Over Light: Vented skylights often come with the option of a blind, allowing homeowners to help control solar heat and UV rays. This feature makes vented skylights versatile, providing direct sunlight when you want it and shade when you don’t.

Reduced Mold and Mildew: Rooms like bathrooms and attics are more susceptible to mold and mildew due to lack of ventilation. Vented skylights can help alleviate this problem by expelling warm, humid air.

So, do venting skylights work? Absolutely. They not only bring in natural light but also offer practical advantages that enhance your home’s comfort and energy performance.

Do You Lose a Lot of Heat from Vented Skylights?

One common question homeowners have is whether vented skylights lead to significant heat loss, especially during colder months. The answer largely depends on the type of skylight glazing you choose and how well the skylight is installed.

Glazing Options: Skylights come with various glazing options, either plastic or glass. For better energy performance, opt for laminated or low-emissivity (low-e) glass. This type of glazing also minimizes the risk of sharp pieces falling in case of breakage.
