Round two for Bill the green builder guy, again, some decent information, though he is a big lovable dork – I agree with a youtube poster that Vinyl Windows get an “F” for sustainability. Spray foam options can be sustainable from the perspective of higher insulation and better energy conservation, I have used them and they can be effective. As for composite decking made from recycled plastic – as much as I hate it, I give it a nod as it is recycled. So long as they source the material from the waste stream and keep it from going into the landfill for a time, I suppose its preferable. Whenever I think of plastic I think about this article in the Chronicle from 2006, and it never fails to piss me off.
