Used XPS Roofmate insulation and IAQ
VapourOpen
| Posted in Green Building Techniques on
I want to insulate my basement walls with XPS. I noticed that there are several places where I live selling used XPS insulation. I wouldn’t think twice about using it in the same application, however in an interior space, I am not sure if it would “smell” or produce IAQ problems.
Does anyone have any experience with this?

Cory,
Unless the XPS pieces are contaminated with some type of asphalt product, I don't see any reason to worry.
All of the material samples i have seen through pictures appear as though there is some grey residue in splotches here and there. I assume that it must be from an asphalt product as I can only figure that roofing applications is the only place where they come from
