Screening & shading.

Screens are, pound for pound, the most cost-effective climate installation in the greenhouse — a single moving cloth beneath the roof that does three quite different jobs depending on how and when it is deployed: it saves energy, it steers light, and it helps control humidity and radiation. Because one relatively inexpensive installation touches so many parts of the greenhouse's energy and light balance, screening is very often where a project gets the best return on each euro invested.

The three families each solve a different problem. Energy screens close at night to trap a still layer of air and dramatically cut heat loss through the roof — the fastest energy payback in greenhouse technology, and standard wherever heating is a significant cost. Shading and diffuse screens tame radiation peaks in bright or hot conditions, scattering harsh direct sun into even, deeply penetrating light that lifts photosynthesis while preventing scorch and heat stress. Blackout, or light-deprivation, screens create total darkness on schedule to control photoperiod for light-sensitive crops such as cannabis and chrysanthemum, and to block light emission to the surroundings where regulations demand it.

Crucially, the right screen package is not universal but follows the climate profile. Cold and temperate climates lean on energy screens — often two of them, in a double-screen configuration — to minimise heating costs through long winters. High-radiation and hot climates prioritise diffusion and shade to manage the sun and protect the crop. Many greenhouses combine several screens, each with its own cloth and its own control strategy, to cover the full range of conditions across a year.

All of them are orchestrated by the climate computer hour by hour, balancing energy saving, light and humidity against the risk of condensation, so insulation never comes at the cost of a damp, disease-prone canopy. Which screens earn their place in your greenhouse depends on your radiation and temperature profile — and we compute exactly that.
