Celsius Performance Glass delivers the ideal balance of solar control and high visibility. It blocks even more solar heat gain and damaging UV than typical sunroom glass while still allowing the visible light to stream in. All of this with a minimum of exterior reflectance. Choose the original Celsius for pure performance or Celsius Blue for an unrivaled soft blue tint, making even the darkest days feel bright and sunny.

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.
