The Ondula system is a new covering system totally unique and innovative and it gives the opportunity of protecting from sun and from rain. This realisation is possible thanks to the alluminium slats and its specialinsliding track, that can hermetically close from rain (6mm/h) and protect perfectly from the sun. The elegant design is the ideal solution for big covering of large spaces, terraces, pergolas. The maximum dimensions are 5 metres of width and 5 metres of extension. Thanks to the modular solution bigger spaces can also be covered.
