What is the 3C mark of fireproof glass?

CCC logo. Class A fire-resistant glass corresponds to insulating fire-resistant glass (composite fire-resistant glass). This type of fire-resistant glass must pass the national compulsory product certification before it can be sold.

The product must have this mark on it to be a qualified product. Class C fire-resistant glass is non-insulated (single piece of fire-resistant glass), and this type of glass does not require mandatory certification. Extended information

When a fire occurs, the fire-facing glass bursts quickly when exposed to high temperatures, and its fireproof rubber interlayer foams and expands about ten times, forming a hard milky white bubble fireproof rubber sheet, which effectively blocks Flame, isolate high temperature and harmful gases. The finished product can be edged, punched, and cut to length.

When applied to exterior windows and exterior curtain walls, the design plan should consider the combination of fire-resistant glass and PVB laminated glass. Scope of application: Fireproof doors and windows of building rooms, corridors, passages, fireproof partitions and fireproof partition walls in important parts.
