The accordion system has been developed by Holland Gaas itself. Exchanging knowledge with greenhouse suppliers, growers and research centres has led to a system that can be optimally integrated into new greenhouse structures because the profiles are already fitted in the greenhouse roof. But Holland Gaas has also thought about existing construction, polytunnels and frameless ventilation windows. By using a supplied cassette system, the netting can also easily be clicked into existing greenhouses.
Because the slats run back to two pieces in the ridge, only a small package is created with a perfect seal. To ensure that the netting folds neatly, we have developed a number of guiding systems. The netting is hardly visible when a window is closed. The quality is guaranteed by the use of a premium quality rubber seal. The built-in UV stabiliser and sustainable materials also ensure a long lifespan. And perhaps most importantly: the constant mesh openings keep out any unwanted insects!
