What Is Safety Laminated Glass Used For?

Replace with laminated glass windows for strength and safety in your property.

Laminated glass is preferred for replacing recurrently broken windows in timber or uPVC frames due to its capability in being strong and reliable after a special manufacturing treatment. For residential and commercial properties, it offers a benefit of higher security as standard compared to normal double glazing.

What is laminated glass? Theoretically, laminated glazing is as strong as normal glass. With the tough PVB (polyvinyl butyral) plastic interlayer bonded between 2 panes, it has a better impact resistance but is still not as tough as toughened glass. The PVB sheet is a resin bond that holds the broken pieces in place when the glass breaks. This reduces the risk of an injury by having sharp fragments falling to the floor.

Advantages

  • 1
    Stronger Glazing

    In the middle of the 2 glass plies, the sticky PVB sheet is able to withstand the repeated strikes of weapons such as metal bars, hammers and sticks. Laminates can be built up in thickness to create a bulletproof shield for added security and is commonly used for royalties, celebrities and other official persons. Thick laminated glass windows are beneficial for resisting natural forces, such as tornados, hurricanes and thunderstorms.

    Safety Glass

    The added plastic polyvinyl butyral middle laminate for this type of glazing is a safety feature. Clients will pick this for their timber or uPVC windows as they depend on the PVB laminated glass to act as a glue to hold shattered pieces together if it breaks. It also temporarily deters from unwanted people trying to gain access into the property.
