Greenhouses have always been susceptible to having a ‘cold side’ despite innovations in both roof and perimeter screening. The cold air ‘trapped’ above a roof screen will invariably collect at one gable end and this can result in a lower temperature in the growing area below the screen at the affected end.

Leen Huisman can now offer a solution to this problem in the form of an Intermediate Apex Seal!

By installing vertical partitions of clear cloth material between the horizontal roof screen and the greenhouse roof, the cold air above the screen is prevented from collecting at one gable end and therefore the temperature differential in the growing area below is reduced.
