• 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

  • Buildings and construction combined account for 36% of final global energy use and 39% of energy-related carbon dioxide (CO2) emissions (Source: UN Environment Programme 2017)
  • 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 For example, in the EU area, 86% of building glass surfaces consists of outdated and less energy-efficient single or double glazing (Source: Glass for Europe)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 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
  • Upgrades extend machinery lifetimes: all previous-generation 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
  • The solar industry is one of the industries that benefits most from using thin glass
  • The main benefit of thin glass in solar modules is that it provides better light transmission of the solar radiation, increasing the efficiency rate of the solar panels
  • 2-mm glass provides optimum light transmission, resulting in higher energy yield
  • 2-mm solar modules are extremely lightweight compared to conventional ones, resulting in lower freight costs and easier handling and assembly
  • GlastonAir with special air flotation technology enables 2-mm glass tempering with excellent quality and without any roller waves, resulting in the thinnest and highest quality glass

Responsibility at Glaston

  • Responsibility is part of Glaston’s everyday way of operating
  • Glaston’s own production processes have only a minor impact on the environment. The largest environmental effects arising from Glaston’s own activities come from the energy consumption of its facilities and from transport
  • Glaston strives to promote sustainable development – both with the products and services it offers to customers and in its own operations
  • The Tampere production plant’s ISO 14001-certified Environmental Management System provides the basis for the management of Glaston’s environmental issues
