The Mono Pitch rooflight is the most common style of rooflight, this is due to its versatility within the pitch (min 5 deg to normally 30-40 degrees) and universal style that allows it to be used over most areas to provide significant daylight. It can also be supplied with specialised glass for both Light & Solar transmittance, along with electrical openers for both smoke and natural ventilation.
