Greenhouse covering film

transparentthermal

We use thermal anti-condensation plastic films from 0.18 mm to 0.22 mm thickness for all our plastic greenhouses. The light transmission percentage for the PE films used is between 88% and 92% depending on the type of film. Which type of film to use is discussed thoroughly with the customer. When doing so we consider the crop and other important requirements, so that the right choice of film can be made to guarantee a perfect growth of the crop. UV stabilisation UV stabilisers in the film neutralise the negative effects of ultraviolet light so that the lifetime of the film is extended. Thermicity Low thermicity is obtained by adding mineral fillers and/or the use of EVA. These substances act as a barrier to the long wavelength infrared radiation and prevent too much cooling down at night. The lower the thermicity percentage the better. Anti-condensation working Adding special additives to the film causes the condensation to spread and form a thin film of water that can be drained off through the gutters. Our aluminium gutters are designed specially to allow the condensation water to be collected. UV-transparent films UV open films allow a high percentage of the UV-B radiation that is important for hardening, colouring and compact growth to be transmitted. Because ultraviolet radiation is not beneficial for all crops UV blocking films can also be supplied.
