Outside screens are used on the top of the greenhouses as the shading materials which also act as anti-hail materials thanks to its excellent high strength. Together with its outstanding shrinkage as low as 2%, the users are able to benefit from its long time effeciency.
Thermal screens offer a flexible and efficient way of improving the management of the greenhouse environment. These screens are designed to keep heat and radiation in a greenhouse during cold periods such as night time and prevent radiation and associated heat entering the greenhouse during hot periods, such as in the middle of a summer day.
This dual capacity makes these materials suitable to a range of conditions throughout the year. They are moveable so that conditions can be adjusted and optimised through out the day and night. Thermal screens can reduce temperatures during the day by as much as 10˚C and maintain temperatures during the night by as much as 5˚C.
When heating, thermal screens trap warm air nearer the crop, reduce the volume of air space to be heated and reflect radiation back to the crop. This can reduce heating costs significantly - possibly by up to half.
Under extreme, hot conditions, thermal screens are also valuable in reducing incoming radiation during the day. This reduces the heat load in the greenhouse and assists in maintaining humidity around the plants and reducing plant stress.
The use of screens needs to be carefully managed to make sure that plants remain actively growing
