Environmental Benefits

As one of the UK’s largest glass manufacturers, Saint-Gobain Glass UK places environmental concerns firmly at the top of our agenda.

We recognise that glass manufacture is an energy-hungry process, so we have worked hard to pinpoint areas that can be managed more efficiently and to minimise any negative environmental impact of our glass manufacture.

Our PLANITHERM products last for many years, and play an important part in reducing the energy consumption of buildings. Over their lifetime, PLANITHERM products can help to save hundreds of times more energy than was originally used in their manufacture.

Focusing on CO2 emissions

The process of manufacturing flat glass for building applications inevitably has a cost in terms of CO2 emitted. However, this is more than compensated for in the savings made by replacing less energy-efficient glazing. The carbon used to manufacture 1m2 of double glazing is saved within 3.5 months if replacing single-glazed windows. In the case of standard double glazing being replaced by energy-efficient double glazing the time is around 10.5 months.

Reduction in carbon dioxide (CO2) emissions is a priority focus of the Saint-Gobain environmental policy. Our emissions remain marginal and lower than the government's permissible levels. However, we go further than the minimum requirements so that we can:

  • Reduce energy consumption and greenhouse gas emissions in our industrial and transport operations
  • Optimise the use of raw materials in industrial operations, which includes control of industrial waste, internal recycling, and designing products to be recyclable at the end of their lifespan

Using recycled glass

An effective way to significantly reduce CO2 emission levels is to feed recycled materials back into the production process. For every tonne of recycled or waste glass re-used In glass production, we save 255kg- 300kg in CO2 emission.

Our glass collection and recycling scheme enables us to utilise 30% recycled material in the manufacture of our window glass – more than any other float glass producer. In turn we have been able to reduce energy consumption at our UK manufacturing plant by an impressive 12%.

The scheme also diverts waste glass away from landfill, results in fewer empty lorries on the road, and enables us to use less energy and fewer raw materials in the manufacturing process, which in turn, produces less of the greenhouse gas CO2.

Recognition and Awards

As a direct result of our unique glass return and recycling scheme, Saint-Gobain Glass has received the Business Commitment to the Environment award and has been recognised as one of the UK’s Greenest Companies by the Sunday Times.

Revised Building Regulations

The government Building Regulations Part L, recently revised in October 2010, set new standards for energy conservation and reductions in CO2 emissions within the built environment. The regulations stipulate that insulating products must be extensively used in the construction of new buildings and that alternative methods of energy production should be explored. As Europe's best selling range of high performance low-emissivity glass, incorporating the very latest advancements in thermally insulating glass coating technology PLANITHERM can easily fulfil these criteria.

Specifically manufactured for the UK market, the thermal insulation of PLANITHERM TOTAL+ is more than three times greater than that of single glazed units and at least 25% more efficient than most installed double glazed units.

Combining excellent thermal insulation with high solar heat gain, PLANITHERM is the most energy efficient window glass available. If you are looking for the most eco friendly windows, insist on PLANITHERM as your energy saving glass.
