Holland Gaas is a pioneer in the development of wire mesh systems. Thanks to its comprehensive product range, you can be assured of the right system with the ideal mesh opening for every type of greenhouse. Light interception is minimal, while the sealing is perfect. Not only that, any risk of diseases and pests is reduced because insects will no longer be able to fly into your greenhouse. At the same time, useful insects will stay inside the greenhouse. Mesh systems are also of paramount importance in controlling the greenhouse climate: they reduce direct weather influences and promote ventilation, even during rainfall.
