SprayChalk and Cool-FX provide extra protection during hot spells
There are a few weeks every year when crops could use some extra protection. On top of an existing coating or as a temporary chalk layer. SprayChalk offers an easy and effective solution in such situations.
Interest in SprayChalk has noticeably increased in recent years. The reason for this is that summers are getting hotter. Not only in countries where greenhouse growers are accustomed to long periods of heat, but also in countries with a moderate climate.
Combinations are feasible
In actual practice there are two types of users. The first category consists of companies that use ReduHeat, ReduFuse or ReduFuse IR to protect their crops. This provides their crops with a uniform mild climate. Some additional sun protection with SprayChalk is then only required for a short period of time in summer. This extra protection prevents a slowdown in growth, growth disorders and quality problems, such as blossom-end rot. The other category consists of vegetable growers who normally do not use any coating. These growers stand to benefit a great deal from SprayChalk during the few hot summer weeks.
All ReduSystems products are compatible and can be applied on top of each other without any problems.
This gradual climate change makes it necessary for everyone to look at protection in summer from a different perspective. SprayChalk is an ideal solution in this regard. It is a liquid product that is easy to apply. The layer’s thickness determines the quantity of light that is reflected: from 20 to 40% net screening.
Because SprayChalk does not contain a binding agent, it will disappear from the greenhouse roof after a few rain showers. Often that is exactly long enough for the extra hot summer days.
Roof coating for industrial buildings
Not only greenhouses, but factories and industrial buildings can also become too hot during the summer. This creates uncomfortable work conditions. The Cool-FX roof coating decreases the roof’s temperature by tens of degrees. This in turn creates a far more pleasant indoor climate. The indoor temperature can drop by as much as seven degrees.
This can also save a lot of energy, because it reduces the use of the air conditioning.
Cool-FX is a white coating that reflects sunlight. It can easily be applied using a roller or a low-pressure sprayer and is specifically developed for metal and asphalt roofs. Contractors are currently developing special equipment designed to quickly and efficiently apply Cool-FX. Over the next months the coating gradually wears off during rain showers, allowing the roof to regain its original dark colour for optimal heat absorption in winter.

Diffused light virtually always better
All fruit-bearing vegetable crops benefit from diffuse light. The total photosynthesis increases through better light penetration and reduced heat stress.
Three years practical experience with ReduFuse
Coating makes optimal growing possible. Diffuse light clearly can increase production and quality. Over the years this has been proven time and time again by horticultural research trials and now data from commercial nurseries is piling up. ReduFuse allows a greenhouse roof to diffuse light without the...
