natural lighting option will offer the most light and give us all those benefits that we are looking for?


PROVEN BENEFITS Research has shown us that rooflights offer some surprising benefits. Rooflights have been shown to provide at least twice as much light as vertical windows of the same size, and three times more light


than dormers. They can also provide higher wall luminance than dormer and facade windows, resulting in a softer transition between the high luminance of the windowpane and the adjacent wall, therefore reducing the risk of glare. Rooflights offer a better distribution


of light on all floors of a building by balancing the light levels more consistently. The higher levels of light


variation of light levels, increasing visual interest within a room. They can be installed into cellars, basements and balconies where the installation of vertical windows may not be possible. In summary, consider rooflights if you are looking to reduce the energy use from artificial light, to increase the levels of light consistently, reduce annoying glare, or just add light to bring function to an area of a home.
