Roof Lantern/Skylights
What are Roof Windows?
Roof windows are glazed openings installed in the slope of a roof. They are designed to provide natural daylight and ventilation to the space below. Unlike traditional skylights, roof windows can usually be opened, which allows fresh air to circulate while enhancing interior brightness and energy efficiency.
What are Skylight Windows?
A skylight, otherwise known as a sky lantern window, is a fixed or operable window installed in a roof or ceiling to bring natural light into the interior space below. Skylights enhance brightness, reducing the need for artificial lighting, and can improve ventilation and energy efficiency, all while creating a more open, spacious feel within a room.
4 Benefits of Roof Windows & Skylights
So why should you consider a roof window or skylight from us? Well, you can expect the following four benefits when installing this type of window in your home:
Energy Efficiency
Roof windows and skylights are energy efficient because they’re able to maximise the amount of natural light and heat retained by a room. This reduces the need and cost of producing artificial lighting and heating throughout the day.
Ventilation
Because heat rises, the rooms highest in a home can become the hottest. By installing a roof window or skylight, you can enjoy an effective source of ventilation in that space, if the model has an opening function.
Daylight
Roof and skylight windows allow an abundant amount of light to enter a room.
Aesthetic Appeal
With a truly unique design, roof windows and skylights can add aesthetic appeal to your home and increase its value. Another great reason to consider installing them as part of your next home renovation project.

Roof Lanterns & Skylights: FAQs
What’s the difference between a skylight and a roof window?
The key difference between a skylight and a roof window is that:
- A skylight can be installed “out of plane”
- A roof window must be installed “in plane” with the surrounding roof
Are roof windows suitable for flat roofs?
Roof windows can be suitable for flat roofs, but they must be specifically designed for flat or low-pitch installations. These units are built with domed or flat glass tops and integrated up stands to ensure proper drainage and waterproofing.
Do skylights make a room hotter?
Although skylights can make a room hotter, particularly in direct sunlight, modern skylights with low-E glass, ventilation, or blinds can help to reduce heat gain.
