Energy screens

An energy screen is used both to control the climate and to save energy. Different fabric types exist that make a major contribution to the better insulation of the greenhouse and the reduction of insolation.


Sun screens

A typical feature of a sun screen is that it reflects sunlight while maintaining natural ventilation. This is achieved with an open fabric structure, so that air exchange can occur without opening the screen. In this way, a cooler greenhouse climate can be realised during sunny and warm weather conditions.


Growing lights

Due to the ever stricter legislation with regard to light emissions, the growing lights is starting to play an increasingly greater role in illuminated cultivation. Different types of fabric have been developed, where the light interception is variable from 85% to 99%. To take maximum advantage of the air exchange, there are also possibilities to work with two layers one under the other.


Shade screens

The Bom Group’s shade screens comply entirely with today’s high demands and have a long service life. Our professional method of working ensures erection without

gaps so the screen does not let through any light.

You as a grower can use your shade screen to determine day lengths, independent of the sunshine outside.


ABS wire system

ABS stands for 'Anti-Block System' (i.e. anti-jam) and is a unique invention in the field of screen systems. The ABS screen system has already been applied in many projects to the customers’ great satisfaction. As the attachment between the screen profile and the pull wire is implemented using a slip system, the installation always closes fully. In the open condition, the screen package is always kept to a minimum.


Push-pull system

The Bom Group’s push-pull system is driven by steel rack and pinions and steel push-pull rods, resulting in reduced forces on the greenhouse walls compared to other pull-wire systems. This is an especial advantage when multiple screens are used.


Roller screens

The Bom Group’s roll-up wall screens contribute to a more even temperature distribution and consistent growth of the crops in the greenhouse.

The perfect closure of our roll-up wall screens ensures maximum energy saving and reduction of the light entering or escaping. Also, if desired, a greenhouse section can be completely shaded off.


Wall screens

When the layout of a greenhouse has to be altered in a very short time, the Bom Group’s 

Twin Wall Screen is a logical choice. By application of the Twin Wall Screen, the climate in one area of the greenhouse can be separated off.

Twin Wall Screens can also be used to save energy or for shading-off purposes.


External screens

The purpose of external screens is to regulate the climate in the greenhouse better. This can be achieved by ‘screening out’ certain weather factors on the outside of the greenhouse.

Excluding sunlight ensures lower insolation and a lower temperature in the greenhouse. Also, through reduction in the cooling load, lower electricity consumption can be achieved. The roof vents can stay closed longer, which leads to improved CO2 concentrations.

In the colder months, energy savings can also be made thanks to the insulating effect of the external screens.


Insect mesh

The Intranetting© mesh system developed by the Bom Group is optimally integrated into the aluminium roof vent, whereby the following aspects are optimally considered:

• Minimal light loss
• Finish as a whole
• Roof-washer friendliness (greenhouse can be washed better)
• Guaranteed drainage of condensate.


Screen renovation

Our technical consultants can give custom advice about the state of the installation to be renovated. In as short a time as possible we can have your existing system renovated, so that your screen system can again function optimally for many years.
