Roof window

[citation needed] A roof window is often a good option when there is a desire to allow both light and fresh air into the space.

This type of light tube design is often employed with buildings where the installation of a skylight or roof window is not practical.

[1] While a roof window is normally included in the original construction of the building, it is possible to add the design feature to an existing structure.

As long as the framework and the slope of the roof allow for the inclusion of this type of window, it can be installed with relative ease.

Many manufacturers offer prefabricated window inserts for retrofitting into existing roofs.
