Alweco Scherminstallaties B.V. products

The right insect screen will keep harmful insects outside and biological control agents inside the greenhouse. ALWECO has both harmonica and folding systems available for efficient insect control. Without a good insect-repelling system, biological control of insects in a greenhouse is not feasible. ALWECO`s system fits perfectly into the greenhouse and its fine mesh gauze radically stops harmful insects from entering. A tailor-made system (harmonica or folding system) is made for each greenhouse, and any unevenness in the existing greenhouse is smoothed out during installation so that no gaps are left that could undermine the system and thus the control of insects. Tailor-made insect control.

ALWECO`s roof roll screens have been specially developed for wide-span greenhouses, but have virtually the same properties and qualities as all other screen systems. More and more garden centres and production greenhouses are using ALWECO roof roll screens. In garden centres, the climate for plants, flowers and visitors must be perfect. Coloured screen cloths can be used to create an atmosphere that appears warm but still provides the necessary cooling. Ideal for plants and visitors!  Energy saving and light transmission are particularly important in production greenhouses, for which we also have the right screen cloths. ALWECO`s roof roll screens achieve optimum results in all cases.

Stop cold air flows in the ridge of the greenhouse? Simple. Install baffle screens. These transparent screens are easily installed and precisely prevent the cold air flows that cause temperature differences in the greenhouse. Many horticulture companies with a screen installation have to deal with a constant draught above the screen cloth. The air sinks downward, causing temperature differences during cultivation. If the crop is exposed to light, this temperature difference can become even greater. Roof seals have been developed to counteract these temperature differences caused by `cold traps`.

There are many types of screen cloth. The grower has the ideas and the vision, we have the specialists and the cloth to help realise these ideas and visions. A great combination, if we may say so ourselves. The type of screen cloth or film is determined by the system application: energy saving, darkening, sun protection or a combination of these. Humidity control can also be a deciding factor. ALWECO knows the properties of each screen cloth and can therefore recommend the most suitable cloth. ALWECO supplies screen cloths from all the leading screen cloth suppliers.

ALWECO`s blackout screen cloths give growers control over the day and night cycle, making it possible to achieve optimal cultivation with consistent quality all year round. Sometimes darkness is better than light in order to achieve the plant`s ideal flowering process. Total darkness is possible by using two or three layers of screen cloth in the horizontal screen installation. Each design is made to measure and assembled by a skilled installation team, ensuring that not a single ray of light enters the greenhouse. Darkening without concessions, completely light-proof.
