Light is essential. Our accordion system is a compact, foldable package, which ensures the light intensity remains at a maximum in the greenhouse. Because the slats run back to two pieces in the ridge, only a small package is created with a perfect seal. Maintenance takes little time: annual cleaning with only water is sufficient. Besides the constant mesh opening, the quality of the accordion system is guaranteed because of the use of only high-quality materials. Insects do not stand a chance!
