Thermal Films Bulletin

Most of us are aware that the greatest energy loss in a greenhouse is through conduction, and the greatest savings are realized with a double layer glazing system such as the typical inflated double poly house. Studies have shown that a properly inflated double poly house can save over 40% in fuel costs compared to a single layer glazing. What you may not realize is than an additional 15- 20% can be saved by using a thermal film as one of the layers.

Thermal films lower energy costs by reducing the radiant heat loss from the greenhouse. They act as a shield between your warm plants and the cold night air, slowing the radiant heat loss that naturally occurs when your warm plants come into contact with cold night air. Since the radiant heat loss is reduced, heaters cycle less often and require less energy to maintain their set-point temperature.
