Large-size Class A fireproof windows (viewing windows) such as subway and mechanical and electrical rooms 3000mm x 2000mm


Product Introduction:

Hengbao Large-size Class A fireproof windows, the frame adopts 2.0mm thick high temperature resistant carbon steel, double-sided fireproof board on both sides of the frame and 1.0mm veneer, fireproof glass configuration. It introduced from European high quality FPOS 35mmA1.50 fireproof glass. The glass structure is four layers of 5mm tempered glass and three-layer 5mm FPOS fireproof glue, which are high transparency, good weather resistance, good heat insulation effect. The average temperature of the back surface is less than 140 °C when the fire surface is as high as 1000 °C (only 48° when testing C), and no yellowing, no whitishness, stable and reliable for more than 10 years. The certified size of the single layer glass is 3,000mm in width and 2000mm in height. The whole window meets Class A fire protection requirements of fire integrity and fire and heat insulation for 1.5 hours. It is the largest Class A insulation fireproof that China has obtained the national inspection report and CCC mandatory certification. After two decades of hard work, Heshan Hengbao has taken the lead in solving the problem of legalization of the super-class fire safety observation window of the subway high-speed rail fire control room.

Relevant Application Provisions:

For example, the relevant provisions of 《Fire Protection Standard for Subway Design GB 51298-2018》:

The central control room and the emergency command room (also known as the emergency command room or the emergency meeting room) are important to their nature, but their use time and function are different. The two are both connected and relatively independent, to ensure their use. Time security, especially the central control room. Under normal circumstances, a buffer zone will be set up before entering the central control room, and security facilities will be provided. When the central control room and the emergency command room are placed adjacent to each other and an observation window needs to be set, the opening needs to be fireproofed, so a Class A fireproof glass window is required. For other relevant provisions, please refer to: Code for Fire Protection of Building Design GB 50016-2014 and Fire Protection Standard for Subway Design GB 51298-2018.
