If you are thinking about adding natural light to your home or office, you have probably heard of skylights or roof windows and are wondering if they mean the same thing.
While the two terms are often used interchangeably, they refer to two different types of window installations. They also have some key differences that may affect your decision.
In this blog, we’ll explore the differences between skylights and roof windows, their benefits and drawbacks, and help you determine which option is best for your specific needs. So, whether you’re looking to brighten up a dark room or want to improve your home’s energy efficiency, read on to learn more about these popular window installations.
What are skylights and roof windows?
Skylights are types of roof windows that are installed on the roof of a building, mostly flat roofs, to allow natural light to enter from above. They can be made from a variety of materials, including glass, acrylic, and polycarbonate, and are available in various shapes and sizes. Skylights are mostly fixed and do not open; however, some can be vented to allow for proper air ventilation.
Roof windows, also known as roof lights, are similar to skylights in that they allow natural light to enter a building from the roof.
However, they are typically installed on the slope of the roof and can be opened for ventilation, making them a popular choice for attics, lofts, and other living spaces that require natural light and fresh air.
They are also available in a range of sizes, shapes, and materials, including glass, polycarbonate, and PVC. Moreover, roof windows can also be electric or solar-powered, allowing for more functionality and convenience while being environmentally friendly. You can find out more here.
Differences between skylights and roof windows
While skylights and roof windows both provide natural light to a building, they have some key differences that may affect your decision when choosing between the two.
For example, both skylights and roof windows can be vented, but roof windows can be opened in many different ways depending on their design. Below are other differences between these two types:
Energy efficiency
Energy efficiency is another important consideration when choosing between skylights and roof windows. While both options can provide natural light to a building, non-vented skylights are generally considered to be more energy-efficient.
Moreover, skylights can be designed with energy-efficient features such as double-glazed glass, Low-E coatings, and insulated frames, providing better heat insulation. Additionally, some skylights may include features such as automatic shading systems, which can help control the amount of sunlight entering the space and reduce the need for artificial cooling.
Standard roof windows, on the other hand, may not provide the same level of energy efficiency as skylights, although this will vary depending on their type and model, as some types of roof windows can come with similar features to skylights, such as double-glazed glass and Low-E coatings. In most cases, higher-quality roof windows can provide the same level of heat retention as non-vented skylights.
Installation process
The installation process for skylights and roof windows can also vary depending on the type of window and the structure of your roof. In general, the installation process for both options involves cutting an opening in the roof, installing a flashing system to prevent leaks, and securing the window in place.
Skylights are typically installed on a flat roof, which can make the installation process a bit more complex. This is because the roof must be cut to create an opening for the skylight, and the flashing must be carefully installed to ensure there are no leakages from water pooling. Additionally, the weight of the skylight must be properly supported to ensure that it does not cause damage to the roof.
In contrast, roof windows are typically installed on pitched roofs, and the installation process often requires safety equipment or even hiring professional roof contractors, depending on the type of roof windows you plan to install, particularly balcony windows.
Maintenance
Both skylights and roof windows require regular maintenance to ensure their longevity and prevent leaks. This includes cleaning the glass surfaces, checking the flashing system for damage, and ensuring that the window is properly sealed.
For skylights, it is important to regularly check the flashing system for damage or wear, as this is the most common area where leaks occur. In addition, if the skylight is vented, the mechanism for opening and closing the window should be checked regularly and lubricated as needed.
For roof windows, it is important to regularly clean the glass or polycarbonate surfaces to prevent dirt and debris from accumulating. Additionally, the opening and closing mechanisms should be regularly checked and lubricated to ensure that they operate smoothly.
Skylights vs. roof windows: which is better for your home?
When deciding between skylights and roof windows, there are not many factors to consider, as both are designed to bring in more natural light and brighten up your living space.
Having said that, roof windows are usually a good choice for living spaces that require natural light and a proper amount of ventilation, such as attics and lofts while installing skylights can be beneficial for existing dark spots around your home.
Ultimately, the decision between skylights and roof windows will depend on your specific needs and preferences. If you’re still unsure which option is best for your home, consult with a professional installer or contractor who can help you make an informed decision.
