Railway Carriage Interior Train Window Insulating Glass
Product overview
Insulating glass means separating two pieces of glass through effective sealing material and spacer material, and a desiccant that absorbs moisture is installed between the two pieces of glass, so as to ensure that the inside of the insulating glass is a dry air layer for a long time, and there is no moisture and dust exist;
Two pieces of flat glass are separated by molecular sieves, the middle is filled with dry air, and the surrounding is sealed with organic adhesives and other methods. It has good thermal insulation and sound insulation performance.
