Potential large-scale producers of laminated safety glass "triplex"; in Russia are Open Joint-stock company "Mosavtosteklo", NPC "Steklostrovcomplect", Open Joint-stock company "BAMO FLOAT GLASS" and Open Joint-stock company "OSPaZ" - Oryol. They have industrial devices for production of “triplex” with maximum glass sizes: 2x3 meters for windows.

In the USA commercial and residential buildings are glazed with "triplex" laminated with the above types of Butacite ® PVB interlayers, and also latest trademarks Spallshield ® and SentryGlas ® Plus

It is notable that since 1995 it has been forbidden to glaze the two first building floors with ordinary glass in developed European countries.

Information on building polyvinyl butyral (PVB) INTERLAYER Butacite ® production of DuPont de Nemur USA

Building polyvinyl butyral (PVB) interlayer is used all over the world for production of laminated safety glass, so called “triplex”. Basically laminated safety glass is applied to glazing various buildings and constructions.

In Russia “triplex” is generally used” for production of glass packages of different types.

The most important advantages of PVB interlayer in production of triplex glass are:

  • big performance under impact and safety;
  • resistance to penetration;
  • the glass fragments remain firmly bonded to the interlayer if a glass breaks;

Application of pliable “triplex” glass – armor glass, used in banks, high class stores and in high security buildings serves as an obstacle to intrusion and excludes usage of metal bars.

In office buildings partitions, balustrades and various staircases can be made of laminated safety glass “triplex”.

In the world building laminated glass with clear and tinted PVB interlayer is applied to construction of sky-scrappers, galleries, stadiums, railway terminals, airports, high technology plants, atriums, swimming pools, big aquariums, oceanariums and many other installations.

It is notable that laminated glass can be not only flat but also acquire various curved forms.

Laminated glass is produced on specialized factories by vacuum or roll method depending on required configuration of the glass surface ordered by the customers.

What is more, various designs are used, outside or inside fences may be made in the form of stained-glass windows of different types and constructions.

Specifically DuPont worked out a method or producing "Sentry Glass ® Expressions" decorative interlayers digitally printed in full color which can be used for stained-glass windows as well.
