These are excellent and optimal examples of insulation retrofits on existing homes,  If anyone reading needs siding and/or their roof replaced -- follow the exterior insulation method!

We would remove the cladding and insulate the exterior of our bungalow using the "persist" method in a heartbeat if it weren't for the excellent condition of our existing stucco which would cost thousands and thousands to replace.....

For our home we are looking at a slow rise cavity fill closed cell polyurethane for to bring our existing walls up to an r-vaule of ~R24.  Cellulose and open-cell, traditional retrofits, while cost effective and easy to install are very likely to create moisture problems with our stucco, by storing water in our old vapor permeable wall assembly.  We are searching for a suitable closed cell product so that the interior wall cavity will be vapor impermeable.  Any moisture could dry through the exterior stucco or interior plaster, and not be trapped inside the stud cavity as might be the case with an open cell product that would hold water in our wall like a sponge.

A few resources I have collected on the only slow-rise polyurethane closed cell foam I have found:

Sometimes we need to look outside of our home and really become involved in what type of communities we shape with our infrastructure spending. These issues will be on my mind when I vote.

Building Is An Act of Faith -- faith in your design, your team, your scaffolding, the weather, and yourself. Bit by bit that faith is rewarded and strengthened. Nails, glue, and brackets may hold your structure together, but the belief in each other is the the bond that sustains this activity.
