There are different types of screen systems and many different types of screen cloth. The choice of screen cloth is determined by the question: what do you want to achieve with the screen system? Many production greenhouses use wire systems with aluminium profiles and slip blocks. The slip blocks are used to prevent cracks forming in the system and also to create a uniform gap in the screen to allow humidity to escape.. Because greenhouses are becoming ever larger and many are fitted with aluminium gutters, the application of slip blocks can remedy any expansion or shrinkage in the system. There is also a push-pull system with aluminium profiles with optional spring blocks. This system exerts less force on the end walls.
