Select the most appropriate system for your needs
Ensure the appropriate size of Solatube® Daylighting System is selected, which is dependent upon the area to be lit. Also take into account the ceiling to roof height — if it is higher than average you may need to consider a larger diameter system.
Measure the distance between the roof and the ceiling to determine the quantity of extension tubes required. All reflective extension tube joints should overlap a minimum of 50mm and be fixed together using the aluminium tape (provided) and for very long or angled tube lengths, use the self-tapping screws (provided) is recommended.
Having identified the appropriate Solatube diameter and system length, next on the agenda is the roof flashing into which the dome is fitted above, and the reflective tubes below, The flashing's purpose is, while stopping the ingress of the outside elements, to position the dome so that it can capture the optimal amount of natural daylight. From the point of view of capturing daylight, Flashings come in two varieties, Parallel and Angled.
