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.
