Can Solatube Daylighting Systems tolerate very heavy rain?

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.

Are there any issues with leaks?

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.

Are Solatube Daylighting Systems maintenance-free?

The Solatube® Daylighting System features passive daylighting technology that does not rely on moving parts, making it virtually maintenance-free. All assemblies (dome, flashing, tubing, diffuser) have seals to prevent bug and dirt infiltration. In addition, the dome and flashing are designed to eliminate debris build-up. Unlike traditional skylights, that need periodic cleaning and inspection, the Solatube Daylighting System does not require ongoing maintenance.

How can condensation be managed?

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.
