What kind of exterior rigid insulation should I use?
I am working on a series of small 1950 vintage homes. I am planning on filling the walls with cellulose blown from the outside, adding exterior rigid insulation, and re-siding. The exterior finish is not yet known, but I would like to offer the Architect something that works regardless what is chosen (within reason).
I had been thinking about some kind of un-faced extruded foam (so that I do not add any vapor barriers to the system) but people keep giving me funny looks when I say this.
