The coefficient of thermal expansion of borosilicate glass over the temperature 0 - 300°C is 3.3 x 10-6/°C. This is very low when compared with other glasses and metals. That is why, borosilicate glass is often called low expansion borosilicate glass. Specific heat Specific heat between 25°C and 300°C is average to be 0.233Kcal/Kg, °C

Because borosilicate glass doesn’t expand like ordinary glass, there is a smoother transition between temperatures as well as the ability to withstand different temperatures at the same time. Borosilicate glass has an extremely low coefficient of linear expansion (3.3 x 10 –6 K –1 ) as a result of its low thermal expansion.
