Pursuant to an article that appeared several issues ago in MR, I am curious if anyone has done anything with a product called "Poly-Iso foam". I am in the process of planning my layout (not my first, but do not want it to be a disaster, either), and am entertaining several media options. Any feedback as to its working nature, applications, and reliability would be much appreciated.
It will be basically a seaport theme with docks, carfloat facilities, and associated environs.

Polyiso foam is similar to polyurethane foam, except that is does not require the fire breaking of sheetrock. I have not seen it in sheet form, but it is used in spray(new) or injection(existing) construction. I suspect the cost may be higher than polyurethane sheets.

I believe you are referring to polyisocyanurate foam, and if I remember correctly (can't be sure of that!), the International Building Code requires it be treated the same as polyurethane or polystyrene foam. It does burn-check manufacturer's data sheets, e.g., Johns Manville. It is available in sheets.
