What is annealed glass?

Annealed glass is an alternative to heat tempered glass. It is a more cost-effective option, although strength and impact resistance are slightly less. It is less likely to crack or shatter than glass that hasn’t been annealed, and offer better durability against a range of temperatures.

How is annealed glass used?

Annealed glass is the most common glass used in windows. It is also often used in the home or office to create tabletops and is ideal for other low-traffic areas and rooms. Annealed glass can also be curved for use in architectural or interior design applications that don’t require the extra strength of safety glass.

How is annealed glass made?

Annealed glass is heat treated and allowed to cool slowly to ensure internal stresses are reduced once the glass has formed. This makes it less likely to crack or shatter than glass that hasn’t been annealed.

Is annealed glass safe?

Annealed glass is best used in low traffic areas where safety isn’t a major concern. While annealed glass is stronger and more durable than non-annealed glass, it is not designed to shatter into tiny pieces like tempered or safety glass and may pose a safety hazard when smashed.
