Product Overview

Modern prison designs are shifting towards a more open and well-lit aesthetic, aiming to improve the well-being of inmates and enhance spatial visibility. However this creates an ongoing challenge in meeting security requirements for glazing while maintaining natural light.

Cooling Brothers Prison Glass plays a pivotal role in these environments, allowing natural light to flow through spaces while ensuring the highest safety of occupants. Prison Glass shows exceptional resistance to a wide range of prolonged attacks using implements such as axes, mallets, crowbars, and handsaws — tools that are commonly found and potentially used within correctional facilities.

Prison Glass is available in various thicknesses, including 15mm, 17mm, and 22mm, and adheres to AS/NZS2208 safety glazing material standards.

  • Security glass for high security facilities
  • Engineered with structural interlayers to withstand prolonged, high intensity attacks
  • Meets AS/NZS2208 safety glazing material standards
  • Allows natural light to penetrate the space, contributing to a more humane and well-lit correctional environment.
  • Configured with one way vision and IGU

How is custom laminated glass produced?

Laminated glass is produced by joining two or more glass panels with an interlayer, typically PVB or SGP. The glass is permanently bonded by applying heat and high pressure in an auto-clave, a vacuum chamber.

Are custom laminates Grade-A safety glass?

Yes, both laminated annealed glass and laminated toughened glass are classified as Grade-A safety glass according to AS 1288-2006 (Australian Standards) 2023. Our custom laminates fall under both of these categories.
