Heat-Strengthened Glass
Oldcastle GlassŪ' 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.
