Turret extensions

     Living in a northern climate can create some shadowing on certain north facing roof lines depending on they're pitch. The other reason is for build up of ice and snow in some prone areas, in some areas North of Toronto 24" or more of snow or more can build up on roof tops.  Our latitude in the Toronto area is about 44 degrees,  to maximize the amount of light input into the dome assembly Solatube developed turret extensions.  These fabricated collars raise the  height of the dome and are available in 4", 6", 12", 24" and 48" increments.  I had a couple of installations with photos where I used these extension turrets that performed very well extending above the shadow line created by the obstructions.

24" extension turret with dome installed above upper level roof line. In this home the shadowing what quite extensive with the split level roof casting a long shadow. 

Building or Renovating and adding natural light to a lower level?

     There exists the potential to install a Solatube from the roof line (sloped or flat roof) down through the room below to the next level living space.  In some cases the building plans will incorporate a framed in vertical shaft to house the Solatube to line up with the dark area below.  The framed in shaft will line up directly with the floor joists below and the ceiling/roof trusses above to permit the vertical Solatube.  Some of these installations yield a 10ft - 17ft long tube shaft depending on the height of the attic space above the framed in shaft.  Usually this shaft ends up located within a closet, hallway or pantry wall and is dry walled upon completion.  There is a small amount of light loss within this extra length, however the end result is sensational compared to the previously pitch black room below.
