ValkGreenTop | Saving energy with an outer screen

The climate inside a greenhouse is easier to control when certain weather factors can be ‘screened out’ before they enter the greenhouse. Keeping sunlight out, for example, reduces irradiation and keeps temperatures down, which is especially important when growing premium ornamental plants such as orchids and roses.

On top of that, outer screens also help keep power consumption down, because they reduce cooling needs and increase CO2 concentrations thanks to less ventilation loss. And thanks to outer screens’ insulating effect, considerable energy savings can even be achieved over the winter months.

The ValkGreenTop outer screen by Van der Valk Horti Systems sits on the greenhouse’s ridge, which keeps the gutters clear and prevents dirt from accumulating. The lightweight structure is weatherproof and compact, which minimises light interception.
