SprimoSecure Around 1,000m² are produced daily. The glass is hardened so as to be 6 to 7 times more solid and resistant than ordinary (annealed) glass, particularly to thermal shock. And if it is subjected to a force capable of breaking it, it produces a multitude of small shards rather than large sharp pieces. For those two reasons, hardened glass is very safe. -------------------------------------------------------------------------------- SprimoSafe This type of glass, especially resistant and endowed with excellent acoustic or UV-protection properties, is intended for balconies, balustrades or even roofs - anywhere safety and resistance to breaking and entering are essential.
