Pitched Roof Window Buying Guide
Roof Windows - What You Need To Know
Roof Windows are outward opening windows that are installed in to part of the design of a roof, usually a tiled or slated pitched roof. Often confused with a Rooflight or Skylight (Which usually is referred to as Flat Roof Rooflights or Skylights), a roof window differs in a few basic ways.
A Roof Window is often a good option when there is a desire to allow both natural daylight and fresh air into a room.
There are many manufacturers available to choose from including VELUX Windows and FAKRO Roof Windows.
While a roof window is sometimes included in the original construction of the building, it is possible to add a window to an existing roof. Usually as long as the framework and the pitch of the roof allow for the installation of a roof window, it can be installed with relative ease. Many manufacturers offer ready made flashing kits hat can be installed by a professional roofer in a matter of hours.
What Size Roof Window?
The size of the window will make a big difference to the amount of light in a room. Manufacturers like VELUX and FAKRO offer a huge range of sizes and combinations forcustomers to choose from.
When purchasing a Roof Window, most manufacturers sizes usually refer to the external frame size.

Top or Bottom - Top Hung vs Center Pivot
So you know the size of the window you are looking to install, but do you need a Top Hung or Center Pivot window? This question gets asked all the time so lets try and narrow things down to help make that decision.
Center Pivot is usually the standard option. Usually there is a top control bar which makes it easy to open even with furniture under the window. Some windows like VELUX, have a design where the unit can be rotated 180° for cleaning. Usually all Center Pivot windows are available in manual, electric or solar operation. But it is worth noting that Center Pivot windows are suited for roof pitches between 15° and 90°
Top Hung Windows open outwards for an unobstructed view. Usually Top hung windows open any position up to around 45°, depending on manufacture. Top Hung Windows usually come with a convenient bottom handle which makes it easy to reach. And worth noting again that Top Hung windows are suitable for roof pitches between 15° and 55°, rather than 90° like Venter Pivot. (Again this may change slightly depending on manufacture)
So hopefully this helps make the decision on what type of operating window you need.
