A tubular skylight is a handy device you employ around your home or business to control the light of the sun as it steams down. Once the sunlight enters the skylight, it is gently filtered down into your home or business with the use of a translucent diffuser lens, so once it reaches you and those around you, the light is gentle and inviting. Install the skylight and its diffuser lens to take advantage of its properties.

Instructions

  1. 1

    Go outside and carefully climb up the ladder until you are on the roof. Set the dome where you want to install the skylight and draw a circle around it with the marker; this is how much roof you need to cut out for installation.

  2. 2

    Cut along the marker lines with the power saw to clear the roof and install the included foam seal, exterior dome, clamp and storm collar by attaching them together by hand; insert the dome into the hole.

  3. 3

    Go inside and head to the area of the ceiling that is below where you just installed the sunlight's dome.

  4. 4

    Climb carefully up the ladder until you've reached where the bottom of the skylight will be installed.

  5. 5

    Place the included insulator disk on the ceiling, and draw a circle around it with the pencil; this is how much ceiling you must cut out for the skylight to fit.

  6. 6

    Turn the battery-powered drill on and drill the circle out with it. Clear any wood or ceiling debris by hand.

  7. 7

    Insert the tube through the hole you just cut out to connect it to the dome and seal the bottom of the tube with the flashing by hand.

  8. 8

    Attach the included interior seals, insulator disk and diffuser together by hand and secure them to the tube; your skylight is now installed and it will diffuse sunlight that filters down through the roof's dome.
