  Paint-on insulation can address the pervasive problem of uninsulated walls in older homes. While it is easy, in most cases, to put conventional insulation above ceilings and under floors, sealed walls must be opened and resealed or have insulation pumped through holes, which must then be patched. The cost/benefit ratio of insulating existing walls therefore can be marginal, and homeowners often skip doing it.
