In common with all glazed structures, temperature reduction under night time or cooler weather conditions will lead to the possibility of condensation. Although the inclusion of thermal breaks on all major assemblies minimizes the risk, the use of background heating is also important, as is the utilization of adequate ventilation. Provisions to maintain an internal temperature between 10-15 degrees above the external ambient temperature is recommended.
