One of the main reasons people opt to install rooflights in a building is to increase natural daylight.
Efficiency - One of the key benefits of rooflights is that they help cut your light bill. In a busy warehouse or office, you are going to need a good high quality light throughout the day. Sunlight can also heat up your spaces which can considerably cut down on your energy costs
Privacy - With homes and offices being built in ever-greater proximity to each other, it has become a challenge to provide plenty of access to natural daylight while also preserving the privacy of a building’s occupants. A roof light can solve that problem effortlessly. Installed on your roof, the lack of an angle to your skylight prevents any users of nearby buildings peering in but still allows in as much light as possible.
