Retractable thermal screens
Retractable thermal screens (also known as shade screens or climate screens) are the most cost effective and energy efficient means to reduce greenhouse energy costs. The system will close when the light levels are excessive and open when the light is limited. This system will also reduce dew drop and heat loss and provide a more constant and comfortable greenhouse environment.
The system is driven by a motorised drive system and can be operated either manually or connected to an environmental control system. With a lifespan of 8-10 years, these thermal screens will allow you to reduce heating costs by 20-70%, stabilise the climate in your greenhouse, and reduce fungal diseases.
We offer a range of models to suit different crops. Most greenhouses are designed with good natural roof ventilation. If you are growing in a hot summer environment, you need Open Weave Screens. These screens have gaps between the aluminium strips that allow warm air to rise through them, while the strips reflect unwanted light back out of the greenhouse. These screens still give significant energy savings of up to 30%.
If you are growing in a cooler climate and have high heating costs, or if you need to modify the day length, you need Closed Weave Screens. These screens have a clear plastic strip between the aluminium strips that helps trap heat, while the aluminium strips reflect unwanted light back out of the greenhouse. These screens give very high energy savings of up to 70%.
Blackout Screens are used to shorten or lengthen the day, useful for flowers like Chrysanthemum and other crops. We can also install retractable/roll-up blackout screens against the sidewalls of most greenhouses, if required.
