Certhon bundles the know-how and experience of two well-known names in international greenhouse horticulture: Wilk van der Sande (technical installations) and Bosch Inveka (greenhouse construction). Two sister companies who have worked closely together for many years, and who became officially united under one name in 2011.The integration of two companies under one roof was a conscious choice: a greenhouse and its technical installations are an inextricable whole. The bundling of know-how right from the start of a project offers many advantages: optimisation of the project and the logistics, saving time and money. It is a methodology which guarantees the best possible end product, which meets all requirements. In turnkey projects in particular, the combination of expertise gives added value. However, Certhon is equally pleased to undertake partial processes: construction of only the greenhouse, for example, or renovation of a heating system.Certhon is still very much a family firm. The four Van der Sande brothers are the company directors. The close involvement by employees and the short lines of communication are characteristic for our approach. Certhon invests in young people and attaches great importance to the personal development of its employees. There are plenty of growth perspectives for ambitious professionals. We have all possible knowledge in-house, and the long service record of our team ensures continuity of this know-how.Activities include sustainable energy solutions and application of renewable energy sources (for example solar energy, geothermal energy). Projects are executed all over the world (America's, EU, C&E Europe, Far East, Middle East, North Africa, Sub Sahara Africa).
