Heat Strengthened Glass
Glass heat-strengthened glass is approximately twice as strong as annealed glass of similar thickness and configuration. Heat-strengthened glass generally fractures in a manner similar to annealed glass and tends to remain in the opening when broken. It is intended for general glazing where additional strength and/or resistance to mechanical and/or thermal stress are desired. Heat-Strengthened glass is NOT a safety glazing product and therefore should not be used where safety glazing is required.
