Are Sun Tubes Any Good

Generally speaking, rigid sun tunnels can offer up to 20m of effective light distribution. Flexible sun tunnels meanwhile cost less and are much better for shorter distances, as the flexible tube allows you to negotiate around any obstructions in the roof space.

Are sun tubes worth it?

Solar tubes are generally not a replacement for electric lighting; rather, they are best used as an alternative to a natural skylight. While you won’t get a view of the sky like you would with a skylight, they are usually a lower cost product that can be easy-to-install and reliable alternative to skylights.

How well do solar tubes work?

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.
