• Safety glass – tempered or laminated – helps protect people from injuries, as it is up to 5 times stronger than ordinary float glass
  • Tempered glass – if broken, breaks down into small, almost harmless particles
  • Laminated glass – if broken, is held in place by an interlayer
  • The use of safety glass is regulated by international standards. Tightening safety legislation and building codes are driving the increased demand for safety and security glass
  • Safety glass applications: façades, shopfront glass, balcony glass, terraces, roof glazing, insulated glass units, railings, balustrades, curtain walls, burglar-resistance glass, sound-insulating glass, walk-on glazing
  • In the automotive industry, the use of glass is increasing in the exterior and interior. New functionalities and glass types as well as safety requirements increase processing complexity and quality requirements
  • Glaston offers the most comprehensive product portfolio in the industry

Energy efficiency

Energy-efficient buildings

  • In 2020, buildings accounted for 36% of global energy demand and 37% of energy-related CO2 emissions (Source: UN Environment Programme 2021)
  • The energy-saving potential in buildings is enormous. For example, in the EU area, 86% of building glass surfaces consists of outdated and less energy-efficient single or double glazing (Source: Glass for Europe)
  • Glazed glass is an essential construction material for low-energy buildings. High-performance glazed surfaces like double and triple insulating glass units, can help reduce the energy consumption of both heating and cooling. Triple glazing helps achieve extra energy savings and is essential for nearly zero-energy buildings
  • With the proper design, the amount of natural daylight through windows can be maximized, lowering the need for artificial lighting

Smart glass brings new opportunities for buildings:

  • Smart glass windows regulate thermal and light transmissivity
  • Integrated solar panels can produce energy

A key focus is on the energy efficiency of glass processing machines

  • The energy consumption of Glaston’s main products has been substantially reduced with the R&D efforts of our heating and cooling technology. In the tempering process of low-emissivity glass, savings have been approximately 30% over a 10-year period
  • Electricity consumption in the equipment used in the manufacturing of glass pre-processing machines and insulating glass units is low and as a result of product development, consumption has been reduced even further
  • Upgrades extend machinery lifetimes and Glaston machinery can be upgraded with the latest energy-efficient technologies


  • We spend over 80% of our lives in buildings. Natural daylight and proper sound insulation significantly contribute to our well-being
  • Well-designed sound environments in schools and offices enable better communication and help improve concentration
  • In hospitals, lower noise levels and a visual connection with the natural world outside help patients recover faster
  • In private homes, protection from noise creates a sense of security and privacy
  • Large laminated insulating glass units enable effective sound insulation and more natural daylight
  • Glaston ProL allows the flexible production of all types of laminated glass with up to 50% in energy and waste savings


  • Glass generates a minimal environmental impact
  • Glass is made of non-polluting raw materials, such as sand, soda ash, limestone and dolomite. The glass manufacturing process is highly energy efficient, requiring low levels of water and generating minimal waste
  • The majority of glass products for buildings are recyclable at the end of their useful life, contributing to lower environmental impact
  • When recycled into new glass products, glass waste helps save both raw materials and energy in the manufacturing process

Solar applications

  • Demand is growing for solar energy applications, such as solar panels, smart windows and integrated façades
  • Glass used in solar cells, mirrors and panels is subject to the highest quality requirements for glass thickness, durability and curved surfaces
