GLASS DESCRIPTION
●MIGO Clear Float Solar Glass is produced by processing high quality clear float glass in continuous tempering furnace. After tempering treatment, it is 4-5 times stronger than ordinary annealed float glass and, if broken, disintegrates into small fragments with dulled edges that are unlikely to cause serious injury.
●Light transmittance is a bit lower than ultra clear low iron glass, but cost is also lower. It is suitable for area having sufficient sun light.
