Tubular SkylightPlay | Download (Right Click, Save As...)
If you’re trying to get natural light into a space where windows can’t be added, the answer may be a tubular skylight. These things are fairly do-it-yourself friendly and can be installed in a lot of places where a traditional skylight would never fit.
They start with a round hole cut into the roof. A mirrored tube is inserted down through it and the attic space. A self-flashing dome seals the opening on the roof and collects sunlight into the tube.
Inside the house a hole is cut in the drywall ceiling for the tube and a diffuser is mounted over that end to deliver sunlight to interior spaces in the home like halls, closets, and bathrooms.
Because the light is diffused there’s no harsh glare and the mirrored dome on the roof will collect light throughout the day.
