The use of glass applied to curved surface as a building material has increased in recent years. However, the curved glass is difficult to guarantee the quality in process of making it into double glazing, So it is vulnerable to thermal breakage. In this paper, when the glass broken during experiments, surface temperature difference on curved double glazing was compared to that of heat strengthened glass and flat glass. As a result, flat single glass was broken at temperature difference of 100~140 degrees but curved double glazing was broken at that of 40~60 degrees. Therefore, curved double glazing is more vulnerable than flat double glazing to thermal breakage, so it should be considered when applied to building facade.

In recent years, the use of glass applied to curtain wall as a building facade material has increased in our nation. However, the non-tempered curved double glass is very easy to broke because it is difficult to guarantee the quality in process of making it into double glazing. So, it is more vulnerable to thermal breakage than tempered double glass. In this paper, surface temperature difference on curved double glazing was compared to that of heat strengthened glass and flat glass by conducting thermal breakage experiments. As a result, flat single glass was broken at temperature difference of 100~140 degrees but curved double glazing was broken at that of 40~60 degrees. Therefore, it was concluded that curved double glazing is more vulnerable than flat double glazing to thermal breakage, and it should be considered the possibility of thermal breakage when curtain wall glazing is applied as a building facade material.
