Indoor and Covered Growing

Greenhouses & Constructions

Our parent company Bosman Van Zaal has almost a century of experience as a greenhouse builder and they manufacture all their structures in their own factory. Therefore we have the right knowledge in-house to realise the ideal construction for any crop, with natural conditions hardly constituting an obstacle. Moreover, we understand that matters such as light and climate play an important role and we immediately install the best systems in our greenhouse. Are you looking for a robust construction of recognised quality? We will be happy to realise it for you with care and detail.

CMW and Bosman Van Zaal together guarantee first-class support, planning, supervision, and implementation of your project, before, during, and after construction. Whether you are looking for a standard greenhouse or a customised structure, we will supply and assemble the project on time and to professional standards. A wide range of structures and ventilation systems are available, either in standard Venlo bay widths up to 14.4m, wide spans of up to 15.0m, and Cabrio houses with ventilators opening from the ridge. Or for those special situations, Bosman Van Zaal can deliver your greenhouse customised to suit your particular requirement.

CMW are sole agents for Bosman Van Zaal plastic greenhouses in the UK and Ireland. They offer growers not only structures built to engineering standards equal to the best glasshouses, but also the spectral performance of modern plastics and the prospect of significant energy saving.

All Bosman Van Zaal greenhouses can be supplied with double-layered film. This has several advantages, the biggest being substantial energy savings. Compared to a greenhouse with single panes of glass, a Bosman Van Zaal plastic greenhouse using double-layered plastic film with air between the layers uses up to 40% less energy.

Great strides have been made in the development of modern plastic films. Bosman Van Zaal use thermal anti-condensation films from 0.18 mm to 0.22 mm thickness. The light transmission of our films is extremely high – between 88% and 92% depending on the type and whether it is single or double skinned. The most suitable film for your project is discussed thoroughly beforehand taking into account the crop and other important requirements, so that the right choice can be made to ensure perfect crop performance. Special films such as F-Clean® and energy saving double layer films can be supplied on request.

Modern films have properties that can influence plant growth and development, contribute to energy saving and even play a part in pest control. Growers are becoming increasingly aware that plastics, far from being a poor relation to glass, actually bring real benefits to crop production by enabling the light spectrum to be manipulated so that only those wavelengths which ensure the best growth and development reach the crop.
