Condensation in homes or buildings is mainly a winter problem. It occurs most frequently in areas where warm, moist air is generated and allowed to penetrate to colder parts of the building. A number of activities can produce moisture, including cooking, bathing, washing dishes and/or clothes, heating, and humidifying. Condensation may be more severe in buildings with inadequate ventilation.
In Solatube® Daylighting Systems, condensation can occur when warm, moist air enters the tubing or the space between the flashing or curb cavity. If this happens, it’s likely that moisture is also present around or on other building elements, such as windows, doors and skylights.
While condensation cannot be eliminated entirely, Solatube International has made design changes to its daylighting systems over the years to reduce its occurrence. The current systems are designed to allow warm, moist air to escape at the dome level while preventing air infiltration in the tube run and at the diffuser level. Modifying your system with a Dome Upgrade Kit, Flashing / Curb Insulator, Effect Lenses, Severe Climate Glazing, or Curb Cap Insulation Kit may also help, but your local Solatube International, Inc. expert is best-suited to determine if these improvements or other changes will help minimize condensation in your Solatube Daylighting System.
Due to the numerous contributing factors to condensation in a home or building, Solatube International, like most window and skylight companies, does not cover it under the manufacturer’s warranty. As such, please be aware that there may be a charge for the service call and/or additional parts needed to upgrade your system.
When just the roof is covered with snow, it may actually increase light output as the white snow makes the roof more reflective. When the dome itself is covered with snow, light output will be reduced but the dome will continue to perform. Tests have indicated that all Solatube® Daylighting System models can resist positive snow loads up to 150 pounds per square foot. For more information and to review the CCRR test report, click here.
The Solatube® Daylighting System captures ambient light so well that you can actually see a nice glow from your fixture on full-moon nights. If you prefer, you always have the option to add a Solatube Daylight Dimmer to block out unwanted light.
Solatube® Daylighting Systems have a variety of seamless, self-mounted flashing options, curb-mounted caps and roof accessories that, when combined with the dome and seals, provide a virtually leakproof system.

Our products feature dome optics that help collect low-angle sunlight, which is extremely important in northern latitudes. As a result, Solatube® Daylighting Systems have performed successfully in cold weather climates like the Northern U.S.A., Canada, and Northern Europe for more than 20 years.
Solatube® Daylighting Systems maximize the amount of daylight available for lighting your interior, regardless of sky conditions. Our proprietary Raybender® 3000 and LightTracker™ Technologies in our domes combined with our Spectralight® Infinity Tubing transfer the maximum amount of daylight from the rooftop down into the interior with minimal light loss, even on cloudy days. Keep in mind your light output is always relative to your light input. There will be a noticeable difference in light intensity between a clear, sunny day and a heavily overcast day. Our diffusers and Decorative Fixtures keep a consistent diffusion pattern, regardless of light intensity.
Yes, all Solatube® Daylighting Systems are designed with features that prevent water from entering the system. The round shape of the domes themselves prevent water from collecting on the surface.
In addition, the circular and seamless, one-piece design of the self-flashing systems allows rain runoff to naturally flow past the daylighting system. As a result, the flashing has no weak points that could separate and allow water to enter. However, an optional turret extension may be added to raise the dome above the roof deck where required.
For curb-mounted applications, the height of the curb would raise the dome sufficiently to avoid any rain runoff. The curb itself (made by others) would typically incorporate a water diverter (cricket) for sloped roof applications.
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.
