Windows: Evidence of a clear contribution to sustainable construction

A Defra funded report published today summarises the impact that windows have on the environment in the first step to providing industry best practice on sustainability.  In particular, it concentrates on:

  • evidence about the environmental, social and economic impacts at each stage of the product’s lifecycle – from raw materials, through manufacture, installation, use and end of life;
  • the wide range of Government and industry actions already being taken to tackle any impacts; and
  • what areas can be considered for future action and improvement.

The report establishes that wood, PVC and aluminium frames all have a role in the future of windows – and a place to play in creating sustainable buildings.

This report has been produced collaboratively by Government and industry representatives, and is one of many actions to help deliver the Strategy for Sustainable Construction.

The next step for the Government and industry organisations involved, is to agree a voluntary action plan for tackling some of the areas highlighted in the report.
