Polythene Options:
Option 1: The standard polythene we use is a 1000G Thermic Anti-Drip Polythene. This is a clear film with the additional benefits of Thermic and Anti-drip properties.
'Thermic' - raises the temperature of the internal temperature by approx.1 to 2 Degrees celsius above the outside temperature.
'Anti-Drip' or 'Anti-Fog' - condensation evaporates or rolls off the polythene.
Option 2: Diffused Thermic 840G Polythene - This is a diffused film with the additional benefits of been Thermic.
'Thermic' - raises the temperature of the internal temperature by approx.1 to 2 Degrees celsius above the outside temperature.
'Diffused' - the sun's rays are 'dispersed' or 'diffused' to prevent plant scorching. The same amount of light is allowed in.
Polythene Warranty: A manufacturer's warranty against UVI degradation of the polythene is 5-6 years depending on the type of polythene picked. This warranty does not cover accidental damage, malicious damage, storm damage or general wear and tear etc.
