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.
