PVC windows have received top marks for environmental performance in a key international sustainable building rating system.
UK based Building Research Establishment (BRE) awarded uPVC (unplasticised PVC) windows an A+ for commercial windows and an A for residential windows in its 2008 update of the Green Guide to Specification tool.
The tool is designed to guide designers towards more sustainable buildings. The guide covers a range of building categories and gives a score from A+ to E for all planned building elemental categories of external walls, internal walls, upper floors, ground floors, roofs, landscaping, windows and thermal insulation.
Sophi MacMillan, Chief Executive of the Vinyl Council of Australia, says the score for uPVC windows reflects the range of benefits provided as well as the environmental impacts.
