Installed inside the glass structure to prevent strong sunshine (during the day) and/or to prevent the air in the glasshouse from cooling off (day and night). The system most used consists of a cord attached to a rod which connects to the screen or a pull/push rod to move the screen backwards and forwards. The standard shadow screen is usually open, reflecting light on one side only; the thermal screen closed and transparent, the combination screen closed, partly reflecting light on one side only.
Installed along the sides of the glasshouse to prevent strong sunshine (during the day) and/or to prevent the air in the glasshouse from cooling off (day and night). The system consists of a motorized roller device. The standard vertical screens correspond with the horizontal screens.
Completely closes off sections in the glasshouse. This is often done to shorten daylight hours. The system used is a combination of the horizontal and vertical system with the addition of a screen in the middle (at right angles to the glasshouse walls from gutter to ground level). The standard screen is sufficiently lightproof and at the same time controls moisture.
The Partition Wall
Separates sections in the glasshouse. Can be either permanent or movable.
The wall is usually made from a synthetic, airtight fabric and is lightproof.
