Sustainability rating: Wood or PVC?


Looking at the life cycle analysis of both window frames is quite complicated.

You need to judge the materials to see which is the most sustainable. Remember that the data assumed both window frames went to landfill for disposal. Recycling could influence your decision.

PVC window frame


Think about these:


  • Which material has the smallest environmental impact?

  • How do rate things like global global warming and the amount of waste produced?


  • How does production provide jobs for people?


  • How do the materials meet people's needs? Some people prefer the look of wooden windows but they need regular painting to prevent them rotting.



Rate wood and PVC using the table below.


Enter a score for each of the categories.
0 is poor and 10 is excellent.
