PARTIALLY TEMPERED GLASS
Heat-strengthened glasses are also resistant of the broken parts being stuck on the frame. It
to external loads and thermal stresses like has lower impact resistance than fully tempered
fully tempered glasses. Heat strengthening is glass but has a great tendency on façade designs
performed in the same furnaces and at the same due to its higher visual quality.

difference is the cooling process of the glass. The (thermal shock resistance) is 100 °C. Another
