Greneth can build greenhouses for you, but also carry out turn key projects. Venlo greenhouses are available with the following bay sizes: 3,20m, 4,00m, 4,27m, 4,80m. Depending on the type, sections of 4,00 m, 4,50 m en 5,00m are available. Especially in Venlo type greenhouses various ventilation systems are possible. Single, double and continuous ventilation are the options on our Venlo greenhouses. Energy saving is an important issue; GreNeth is building Venlo greenhouses with tightly closing ventilation windows. Recently installing insect netting is an interesting and more common possibility. There is a huge variety in gutters, from narrow aluminium to wide steel.
