Planning for your VELUX skylight - Light shaft application

Determine the position of the light shaft in relation to the skylight already installed (1). Install trimmers in the ceiling (2), following the procedure used when installing trimmers in the roof.Frame the light shaft if necessary. Insulate carefully around the light shaft and finish the inside, including vapour barrier etc. (3).

A skylight shaft is a light well from which the incoming light from the skylight installed in the roof is distributed throughout the room. In simple terms, the construction of a shaft involves cutting the roof opening for the skylight installation, cutting a larger opening in the ceiling below and then framing, insulating and finishing the shaft between the two openings with sheeting. By making the ceiling opening larger than the roof opening and flaring the shaft, you will not only make the skylight and room appear larger, you will also distribute light more evenly throughout the room. A shaft also allows you to direct light to specific areas that need accentuatingsuch as a bath vanity or work area. Painting the interior of the shaft with a light colour will also reflect more light into the room for maximum benefit.
