From more than two pieces of glass, plus inside the desiccant aluminum frame and sealing material composition, it's outstanding advantage is thermal insulation, can reduce the external noise of more than 30 decibels, give people a quiet and comfortable work and living environment. The high-grade insulating glass synthesized by low radiation coating glass has good heat insulating property, and is three times times more than single glass (single glass has the highest heat insulation coefficient of 5 8, while low radiant insulating glass can reach 1.8~1.6).
