Various way of indicating the blending offer by coatings have acquire in literal practice session . This can chair to discombobulation . From now on Mardenkro will create clarity about this .
When ReduSol was insert to the market place , it was customary to indicate the light in the greenhouse as a percentage of the light outside . Many of the control measures in the greenhouse , for deterrent example exit the movable shading , after all are base on the sunlight ’s radiation .
To point the blending provided by ReduSol , Mardenkro also adopted this tradition .
But when you show that the shading percentage is 60 % , for instance , you are talking about a crying part . It is the sum of the coat and all parts of the greenhouse that excogitate or block light . In reality , ReduSol ’s part is then approximately 30 % .
beneficial ignitor incidenceThe gross percentage meter reading was no trouble , as long as the coating were only used for shading . However , it was not very precise either . And today , it really only do confusion .
All nursery builder in recent long time have done their best to improve the sluttish incidence in the greenhouse . Different glass , larger window window glass and lighter construction material . As a result the gross blending percentage declined . The difference between lite reduction in older and novel glasshouse has become very large , while the finish still comport on the button the same way . In other words , this produces a distorted painting .
Furthermore , advanced finishing , such as ReduFuse or ReduFlex were not develop to shield illumination , but to change the visible light into a direction that best benefits the crop . As a side effect they provide a minor percentage of shading , but when you suggest this using gross shape , this by all odds gives you the wrong picture .
This is observable in actual pattern as well ; sometimes this leads to mix-up . When have agreement or comparing products , one should really explicitly identify whether the figures provided concern perfect or last shading .
From now on , only profit shadingMardenkro wants to bring clarity to this issue and this is only possible in one way : by systematically indicate the finish ’s blending using net blending .
Wageningen University & Research ’s Light Lab has tested all of the ReduSystems coating . In the past , only the perpendicular transmission was measured , but today the hemispherical infection is measured . This is the transmission percentage when light comes from all counselling . After all , this is the natural situation , because the atmosphere sprinkle the sunlight , so that it falls on the greenhouse cover from all angles .
This is why Mardenkro make up one’s mind to use net hemispherical transmission . The percentage shading of high temperature and light are based on this . These are very clear figures that only depend on the coating ’s thickness .
Effective 2020 , the ship’s company will only use this net blending percentage in all communication about ReduSystems product . change over this into a gross figure is very simple for that matter . tot 17 % to the net figure for the glass ’ shading and 10 to 20 % for the nursery structure ( depending on the type and the age of the nursery ) .
