Super Clear Polythene 720 gauge (180micron) Designed specifically for the UK where low light levels are common. This film allows 95% light transmission allowing through more of the light spectrum used by plants. It also scatters light entering the tunnel. FOR USE WITH All crops which are frost hardy, where you don’t need to introduce heat, such as over wintered nursery stock, hardy herbaceous perennials, or where the tunnel is only to be used for summer production of vegetables or flower crops.
Thermal Anti Fog Polythene 720 gauge (180 micron) This film has added UV A & UV B filters which dramatically reduce many fungal diseases & condensation. It also contains an Infra-Red additive designed to reduce the speed at which heat dissipates out through the cover – in heated greenhouses 15-20% fuel savings are achieved. FOR USE WITH All crops where heat is important such as bedding/annual plants, propagation houses & over wintered vegetable production. “This is our most popular film”
Super White Polythene 720 gauge (180 micron) This film reduces light transmission to 70% and ultimately the temperature inside the structure. This film is most useful where sun scorch is a problem for growers. It is also suitable for animal husbandry applications and other stock and storage houses where a great build up of heat is not ideal. FOR USE WITH those plants that would normally grow under a shade canopy, species as diverse as camellias and impatiens.
