Tempered laminated glass, made with tempered glass that has enhanced impact resistance, is primarily used in areas with high human traffic, such as railing glass and façade systems. To prevent unexpected breakages caused by nickel sulfide (NiS), Alcam applies the Heat Soak Test (HST) to its tempered laminated products.

ALCAM’s Experience and Expertise on Laminated Glass

The production of tempered laminated glass involves two main processes: tempering and lamination. First, the glass sheets are heated to high temperatures in Glaston tempering furnaces and then rapidly cooled to increase their strength. This process ensures that the glass is up to five times stronger than regular glass, making it more resistant to impact. After tempering, the glass sheets are layered with an interlayer, such as PVB (Polyvinyl Butyral) or SentryGlasXtra (SGX), depending on the desired security level. The glass is then bonded together under high heat and pressure in autoclave furnaces. Alcam ensures the process is carefully controlled in climate-regulated environments to guarantee high-quality results. Additionally, the Heat Soak Test (HST) is performed on the tempered glass to eliminate the risk of spontaneous breakage caused by nickel sulfide (NiS).

  • Railing Glass: Used in high-traffic areas such as balconies, staircases, and terraces to provide both safety and durability.
  • Façade Systems: Incorporated into modern building designs to ensure safety while maintaining aesthetic transparency.
  • Skylights and Roof Glazing: For overhead applications, where impact resistance and security are critical.
  • Glass Partitions: Ideal for offices and public spaces where transparency and safety are both essential.
  • Shopping Mall Railings: Used to provide a clear view while ensuring maximum safety in areas with high foot traffic.
  • Walkways: Offering safety in public areas while providing excellent visibility.
  • Doors and Windows: For locations requiring strong, impact-resistant glass combined with security features.
  • Security Booths: In places where high resistance to impact and security is required, such as banks or government buildings.
