SunMaster & Sterilite SuperThermic Covers Explained
The latest of the smart films from XL Horticulture
Energy efficiency is vital in today's economy. Therefore to have a single skin greenhouse film on you tunnel which is as efficient as glass is an amazing advantage.
The temperatures recorded left relate to 1 day in the winter of 2010 and the trial was conducted by an independent consultant at New Place Nurseries in Sussex (more details are available in our Grower Experience trials).
The graph (bottom left) shows the difference in heat loss. The top line shows how much heat a normal tunnel cover will lose in cold weather. The central line shows how much heat a normal thermic film will lose and the bottom line shows how little heat (infra red
radiation) a SuperThermic film will lose.
The difference between the two films is that SunMaster SuperThermic is UV open and SteriLite SuperThermic is UV blocking.
