JHG fire-resistant glass is combined with borosilicate glass and float glass technology, which fire resistant properties much superior to those of sode lime glass , the main character is :
* high performance to bear high temperature , our tempered borosilicate glass 4.0 can withstand 120 minutes fire test .
* Ultra light ,borostilicate glass 8% less than sode lime glass
* Hign soften point in fire
* High ligh transmission
* No SO2 pollution ,no self-explosion
