PLANNING THE CONSTRUCTION OF A LIGHT SHAFT
FOR YOUR FAKRO SKYLIGHT
Building a light shaft is an integral part of finishing your FAKRO skylight
installation, in the case of homes with flat ceilings. It will bring the light
through your skylight into the room below, and its construction will govern
the distribution of the light within the room.
Making a light shaft involves opening up the ceiling below the skylight and
creating a larger hole within the ceiling, which is then framed, sheeted,
insulated, finish sealed and painted to suit the interior decoration of the
home.
The purpose behind making the opening in the ceiling larger than the sky-
light itself is to create both the visually pleasing effect of a larger room and
distribute the incoming light more widely within the room.
Light shafts can also be used to direct light to work spaces such as kitchen
benches or mirrored areas in bathrooms with excellent results.
Finishing the light shaft in pale shades or ceiling white paints will improve
the light transmission from your skylight into the room.
Decide the location and size of the
light shaft relative to the skylight and
the room.
Prepare the hole in the ceiling using
trimmer timbers in the same way
trimmers are used in roof and wall
construction.
Frame out the shaft, line with plasterboard, and ensure that the shaft is clad
with roofing insulation in the roof cavity. This will reduce heat transmission
from the roof cavity into the home in summer, and help reduce heat loss
from the home in winter.
