Will a Solatube Daylighting System work in hot climates like Arizona?

Yes, Solatube® Daylighting Systems work especially well in hot climates. All of our Daylighting Systems feature Spectralight® Infinity Tubing. This transmits the visible spectrum of light (400 to 760 nanometers), but provides significant blockage of infrared wavelengths greater than 900 nm, which is the main culprit in solar heat gain.

Additionally, the dome ring in the Solatube 160 DS/ISn and Solatube 290 DS/ISn acts as a thermal break between the flashing and tubing to prevent external heat from entering an interior space. In the Solatube SolaMaster® Series, the tube ring performs this same function. In the Solatube SkyVault® Series, R-6 rigid insulation that comes pre-installed in the curb cap roof assembly prevents heat transfer. All of our other curb-mounted units have the option of adding the Curb Cap Insulation Kit for maximum heat transfer prevention.

Also, the Raybender® 3000 Technology featured in many of our products helps to reject overwhelming light and heat when the sun’s rays are most intense.
The Solatube Brighten Up®, SolaMaster 750 and the SkyVault M74 also offer inner dome options that improve thermal performance by creating a dual dome system.
These technologies allow Solatube Daylighting Systems to provide the highest light output performance with minimal thermal impact.
