Starting from the uppermost element, the following information will be required ...
1. The direction to which the roof that is to host the Dome faces
2. The degrees of elevation of the roof pitch.
3. Distance from the apex of the roof to where the Dome is to be located
4. Outer roof cladding - pitched roof with slate or tile. Flat roof finish, lead, bitumen, aluminium, profiled steel etcetera,
5. In the case of roof tiles, the tile brand and/or description of the tile type, such as plain / composite slate, or plain tile, interlocking tile, cement poly tile, etcetera
The occasion of installing a Solatube sun tunnel could be just the right time to consider the status of your loft insulation, particularly if an 'Energy Care Optima System has been selected.For bulk purchasesof insulation, we recommend our associates www.insulation-online.com

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.
The Parallel flashing sit flush with the roof and are most suitable for south facing roofs with a pitch of 30 degrees or less. Angled flashings are designed for use on more steeply pitched roofs, and on roofs that are not directly south facing. They are located as close to the roof apex as possible, so that they can harvest the maximum amount of natural daylight. Equally important, is the flashing's purpose to arrest the ingress of rain, sleet or snow. Flashings should closely fit the contours of the slates, tiles or other external cladding, to ensure the system is water proof
To make it as simple as possible to select the Solatube Kit that is most appropriate to the requirements of your project, we have created a number of complete kits. These kits are categorised, then listed in order of the roof to ceiling install distance. One variable is the Ceiling diffuser, of which the basic 'Vusion' Diffuser is included within the kit price. The facility to upgrade to a more elegant diffuser is included, and is simple to select.
We only sell complete kits. Each kit contains everything that is needed for a successful installation. A small selection of accessories is available to add to your kit, should you feel the need.
