Environmental impact of vertical cladding Downloadable Version
This report reviews how external wall cladding materials have been assessed within The Green Guide to Specification, including the application of the Environmental Profiles methodology which underlies The Green Guide data. The way in which cladding is addressed within building-level environmental assessment schemes such as BREEAM and the Code for Sustainable Homes is also explained.
The report will give manufacturers and specifiers a general understanding of the significant benefits and impacts of external wall cladding products over their whole life cycle and help to identify opportunities for improvements to their environmental performance.
It is part of a series that provides comparable information on insulation, floor finishes, windows, metals, timber, masonry and concrete to assess the environmental impact of specific construction materials.
