Market for extra Rockwool Comfortboard 80

pbout | Posted in Green Products and Materials on

I have about 700 square feet of 1.5” R6 Rockwool Comfortboard 80, leftover from my house project. I’ve posted it on my local Craigslist (Santa Cruz, CA), but wondering if there are green building supply specific sites, either through GBA or someone else. I could only buy this stuff by the pallet, so I would have been happy to find a partial pallet when I was buying materials last year. 
Ad here, which includes a picture of the installation on my house:

    Hi Phil -

    GBA does have a green building bulletin board, but I don't think it is as tuned as Craiglist is for selling small lots of materials, but take a look and see what you think.

      Thanks Peter, I've posted this info to the comments of that thread.
