What are the problems with fire-resistant glass in domestic buildings?

1) Insufficient understanding of the performance and quality of fire-resistant glass.

As for single piece fire-resistant glass, although borosilicate fire-resistant glass has excellent performance, it is generally used as a testing sample due to its high price. Last year, the market saw the emergence of single piece high stress fire-resistant glass, which was more easily accepted by the market due to its lower price and gradually began to circulate. However, there were also problems such as rough edge quality and uneven surface stress caused by poor processing technology, resulting in a lower pass rate for firing inspection.

As for composite insulated fire-resistant glass, some domestic enterprises with inadequate technology produce composite insulated fire-resistant glass with poor weather resistance, aging resistance, susceptibility to yellowing and foaming, poor low-temperature resistance, and short service life.

2) Installation of fire-resistant glass

The fire resistance limit of fire-resistant glass depends not only on the quality of the fire-resistant glass itself, but also on the structure of the fire-resistant glass frame and the way the glass is connected and fixed to the frame. When installing composite insulated fire-resistant glass in an insulated frame system, there should be a certain gap between the glass and the frame. When installing a non insulated frame system using single piece fire-resistant glass, the frame system should clamp the glass tightly without leaving any gaps. So fire-resistant glass should not refer to simple glass itself, but rather to an integrated fire-resistant glass system.
