Each Cesana product is created with excellent quality materials and manufactured with extreme care and attention. Glass and aluminium are the main materials in Cesana products. Glass Glass, available in thicknesses of 8, 6 and 4 mm. is always safety tempered based on the standard EN 12150/01. The tempering process increases the mechanical break resistance of glass up to 5 times. If it breaks, tempered glass crumbles into very small pieces which are not sharp. To confirm its full-fledged “quality culture”, which starts from the design and covers all of the manufacturing phases, Cesana has obtain ISO 9001/2000 certification for its production system. Aluminium Aluminium combines the properties of lightness with an exceptional resistance and strength over time: based on the European standard 9227/93, the frames of Cesana enclosures are tested in a salt spray enviroment, simulating more than ten years of use in humid installations.
