Which rigid insulation is made with high recycled materials?
I'm looking for 2" rigid insulation for the exterior of the house made with high recycled materials. Like 80 to 90%
Thanks Rick

There are not a lot of choices of rigid insulation that are made with that high amount of recycled content. Mineral wool has high recycled content, some brands claim in the area of 90% but it is also very energy intensive in manufacturing. There are wood fiberboard insulation panels, which may or may not be recyled but they are made from a renewable resource, but they also may contain plastics so check manufaturers specs. This page here is likely a good read for you about different rigid insulation options :

Hopefully that page helps a bit, and we can help more, just tell us where you are located, whether it is a new build or renovation, and what the wall assembly is. Two inches is not a lot, so I'm just wondering what else you've got going on in terms of insulation.
