Product Description
Product Overview
Insulating glass for railway carriage interiors consists of two glass panes separated by effective sealing materials and spacers, with a desiccant installed between them to absorb moisture. This construction ensures the insulating glass maintains a dry air layer long-term, preventing moisture and dust accumulation.
Two flat glass panels are separated by molecular sieves, filled with dry air, and sealed around the perimeter using organic adhesives and other methods. This design delivers exceptional thermal insulation and sound reduction performance.
