Velux Sun Tunnels are a wonderful way to bring pure natural light into a small dark area. The best way to achieve this in a small area is a Velux bonded silver rigid sun tunnel. The rigid tunnel is highly reflected so the natural light has a clear path down from the roof to the ceiling. The ridged tunnel can be used for a longer length then flexible, allowing smaller 10” domes to provide a great deal of light.
The flexible tunnel is a great option it you have a shorter run from the roof to the ceiling, and if the room you are lighting is not immediately underneath where the exterior dome needs to go due to some minor obstruction. The Flexible sun tunnel has a ring with a mirror finish just below the dome to reflect light from all angles. To get the maximum light from a flexible tunnel you might consider the 21” dome if you have 24” (on center) rafters to accommodate it.
Whether the Rigid or the Flexible Tunnel is chosen there are two flashings options offered to help you get the maximum light available. The low profile blends in to the roofline and works best for south facing applications. The pitched flashing option is adjustable to gather the light from the desired direction and more suitable for a north facing application. At this time the sun tunnels are available for shingle/shake roofing material and tile with the use of an adaptation kit.
Sun Tunnels are Energy Star Rated. The pre-assembled interior ceiling ring is paintable, and a frosted dual diffuser reduces the possibility of condensation. In no time at all a sun tunnel can save you, and the earth, a lot of resources.
