PVB Laminated Glass

PVB Laminated Glass is manufactured by permanently bonding one or more polyvinyl butyral (PVB) interlayer between sheets of clear, coated or tinted glass under heat and pressure. The polymer interlayer of PVB is tough and ductile, so brittle cracks will not pass from one side of the laminate to the other. While laminated glass will crack if struck with sufficient force, the resulting glass fragments tend to adhere to the interlayer rather than falling free and potentially causing injury.

Laminated glass can incorporate various combinations of clear and tinted glass, transparent or coloured interlayers, as well as a range of high performance coatings. GlaasikTM laminated safety glass are used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. The major application of PVB laminated safety glass is for automobile windshields and architectural fields. PVB interlayers can be purchased in different color sheets.

Core Benefits of PVB Laminated Glass:

  • Penetration Resistance – more difficult to break through
  • Safety – Glass shards are held together by the interlayer
  • Sound Reduction – Reduces transmission of sound through the glass
  • UV Protection – Prevents fading of furniture and fabrics

Strength Variations in Laminated Glass:

  • Normal Strength (NS) for human impact safety
  • High Penetration Resistant (HPR) for additional security
  • High Impact (HI) for security in high-risk applications

Application

  • Automobile windshields
  • Skylight glazing in architectural structures
