The SunTunnelTM from VELUX is a product we often use because it is easy to install and emits a significant amount of natural light. VELUX says the Sun Tunnel skylight is optically engineered to capture light through a high impact dome on the roof. Light rays travel through a highly reflective tunnel, transmitting a pure natural light. A diffuser assembly at the ceiling distributes natural light evenly into a room while limiting bright spots and glare.
Sun tunnels are best suited for asphalt shingled or wood shake roofs with a slope of 14o to 60o.
VELUX manufactures two types of Sun Tunnels:
Rigid Tunnels which can be installed on most roofs.
Flexible Tunnels with reflective tubing that resembles a shiny dryer hose and can bend around obstructions in the attic, rafters and chimney.
Sun Tunnel Options:
Domes are standard arcylic or polycarbonate for debris resistance. A flat glass is available in the rigid line.
If you are installing the product in an area of the roof with a southern exposure, consider low profile flashing that will blend with the roof line.
A night lighting kit, which has a light bulb in the tube to allow the light to be used in evening hours is also available.
A designer lamp, the Lovegrove chandelier, which uses solar lighting to generate light that matches a 60-watt bulb.
Sun tunnels are energy efficient and meet EnergyStar criteria. Sun tunnels purchased before December 31, 2011 can qualify for a 10 percent federal tax credit up to a $200 limit.
Although VELUX says sun tunnels can be installed in two hours by someone with basic carpentry skills, we recommend hiring a professional because of the hazards associated with working on a roof and the fact that most homeowners do not possess the tools required to cut into the roof.
