Screen systems greenhouse horticulture
Installations that can be used multifunctionally
Cut back heating costs
Energy screens result in a substantial reduction in the cost of energy.
Energy-saving
Effectively reduce your energy costs
Energy costs make up a substantial proportion of the total costs of greenhouse horticulture businesses. A screening system with energy-saving fabric keeps those costs down while, if desired, the ingress of light remains at a consistent level due to the high light permeability of the fabric. The desire to reduce the use of fossil fuels and new cultivation techniques such as ‘Next Generation Greenhouse Cultivation’, is clearly reflected in the increasing use of double energy screens in new projects. Government grants are also often geared towards the installation of second screens. Significant savings – primarily in the field of energy – can be achieved through the use of these screens, particularly in combination with roll-up screens.
Why use energy screens?
Protection from the sun
Keep the sun outside
Too much sun is disadvantageous to your crop. Installing sun protection screens allows you to prevent leaf scorch and plant stress, among other things. Thanks to a sun shading screen, you will gain better control of the greenhouse climate. Such screens also offer your crops better protection. Opting for a sun protection screen with a coarse weave guarantees the adequate circulation of air, even when the screen is closed.
Also for energy savings
In cold climates, a coarse-weave sun protection screen is often chosen in order to save energy. Screens like this enable energy savings of up to approx. 68% to be achieved. Energy loss is also limited at night, when the screen is closed.
Diffuse screens
Some sun protection screens make the incoming light diffuse. This diffuse light ensures a much better distribution of daylight over your crop, thus preventing plant stress – and increasing production yield as a result. Light-diffusing screens mainly produce a higher yield in the cultivation of pot plants and cut flowers, although vegetable growers in more southerly countries are also increasingly opting for the use of screen fabric, albeit in a lighter version.
Why opt for sun protection screens?
Assimilation lighting
Contain light emission
Many crops are grown these days with the use of assimilation lighting. The use of assimilation lighting is subject to stringent requirements in various countries in terms of containing the emission of light emission or the nuisance this causes. In many countries, regulations are imposed on this by the government. An assimilation screen prevents the emission of light to the surrounding area. Not only that, because the fabric used in assimilation screens also reflects the light from the assimilation lamps you can optimise the lighting, and therefore the crop yield.
Screens used for crops exposed to assimilation lighting, also called ‘assimilation screens’, reduce light emissions by 99%, making it easy to comply with these laws and regulations.
We pay a lot of attention to the sealing and connection of assimilation screens with the façade screens to guarantee the absence of any cracks or seams.
Why opt for assimilation screens?
Black-out
Crop control
Screen installations for black-out purposes are used to determine the amount of light to which a plant such as chrysanthemums, gerberas or kalanchoes during a specific period. Our black-out systems are also used in the production of medicinal cannabis. At Holland Scherming, you always have the certainty of achieving a maximum black-out rate. As the façade and horizontal systems dovetail perfectly, light transmission is less than 0.1%.
Because of the heavier type of fabric used for these screens, we sometimes opt for a push/pull drive. We can, of course, also install this for you. Holland Scherming systems have a long lifespan yet require minimal maintenance.
Why make use of black-out screens?
Insect repelling screens
Keep insects outside and/or inside
Do you want to keep harmful insects out of the greenhouse and useful insects inside? If so, a mesh system is the ideal solution. Our sister company Holland Gaas supplies mesh for every type of crop and every type of greenhouse, while maintaining optimal ventilation.
Complete range of netting systems
Holland Gaas is a pioneer in the development of wire mesh systems. Thanks to its comprehensive product range, you can be assured of the right system with the ideal mesh opening for every type of greenhouse. Light interception is minimal, while the sealing is perfect. Not only that, any risk of diseases and pests is reduced because insects will no longer be able to fly into your greenhouse. At the same time, useful insects will stay inside the greenhouse. Mesh systems are also of paramount importance in controlling the greenhouse climate: they reduce direct weather influences and promote ventilation, even during rainfall.
