How do you insulate a tubular skylight?
From the attic side, caulk or spray foam where the tube meets the drywall. Cover the tube with R-8 or greater duct insulation that includes a vapor barrier. Use mastic, metal tape (not duct tape), or fasteners to seal the insulation to the light tube.
What is the R-value of a skylight?
The R-values of the VELUX range of skylights, which are all double-glazed, exceed the requirements of the H1 clause in the Building Code (minimum R-value for complete unit is 0.42 m2K/W).
How can you make skylights more energy efficient?
To make skylights more energy efficient, manufacturers use various glazing technologies including heat-absorbing tints, insulated glazing, low-emissivity (low-e) coatings, or translucent insulation material between several glazing layers.
Do skylights cause ice dams?
You see, when snow blocks the normal draining of water from your skylight, it can cause an ice dam. Ice dams increase pressure around your skylight, potentially resulting in leaks. Just make sure your skylight is kept brushed clean of snow, and you should avoid ice dams.
What is a skylight shaft?
The light shaft, also known as the chase or light well, is the area between the skylight on the roof and the ceiling. It is typically enclosed in drywall, but shiplap and tongue-and-groove wood can also be used to finish it.

They also fit into smaller spaces than traditional skylights, making them a practical way to brighten up a small, dim hallway or pantry. Lower risk of leaks – Traditional skylights are well known for their tendency to leak.
Are sun tunnels better than skylights?
In regard to energy efficiency, the solar tube is more effective, capturing light and diffusing it into the home. Though skylights gather three times the light of regular windows, energy is lost through heat gain, particularly in warmer months and climates.
Do sun tunnels lose heat?
It has been patented by Lightway as a feature directly connected to the heat insulation of the building at the access point of the tube and prevents the development of water condensation in the sun tunnel, loss of heat in winter months and excess heat gain in summer months.
What are the drawbacks to solar tube lighting?
