In architectural procurement, mistaking "heat-strengthened" or "tempered" glass for "fire-rated" glass is a high-liability error. While standard tempered glass is often marketed for its thermal resistance, it is fundamentally incapable of stopping the spread of fire.

​For contractors, distributors, and project procurement teams, selecting fire rated glass is not just about compliance—it directly affects project cost, approval timelines, liability risk, and long-term performance. This guide gives you a clear price breakdown + performance comparison + selection logic so you can make a fast, defensible decision.

This article compares the performance and applications of different types of fire-resistant glass, with a particular focus on the advantages and purchasing value of non-insulated 30-minute fire-resistant glass. Combining industry standards and market discussions, it provides B2B buyers with standard analysis, performance comparisons, and selection recommendations to help optimize safety material decisions.

According to the new standard "Safety Glass for Buildings - Part 1: Fire Resistant Glass GB15763.1-2009," issued in 2009, fire resistant glass can be divided into two types based on fire resistance: Class A (insulating fire resistant glass) and Class C (non-insulating fire resistant glass).
