   I've not seen a texture like that, but it sounds like it would be a real bear to duplicate and blend into existing.

   Another option besides rigid foam is spray foam.

   I cannot believe I just typed that. <G>

   I am no fan of spray foam, but it does have its place in correcting situations like what you describe.

   If you were to replace the windows, then spray foam the exterior, and stucco over that, and you would have a well-insulated, durable exterior.

   I would also pay extra attention to moisture control and ventilation. My primary objection to spray foam is that it is not very permeable. If the building does not vent the normal moisture load (cooking, showers, breathing, laundry) you can end up with some serious problems.

   Fortunately, this is easy to address. If you want to investigate further, I would recommend anything by Joe Lstiburek at BuildingScience.com

   been told I pretty much have to apply rigid foam to the exterior to warm the place up.

   Can you stand furring the inside walls out?  That gives you an option which also addresses the moisture inside causing wall problems.

   What's the location/climate?

   Your stucco almost sounds like "popcorn" texture.  That fires a very dim memory of a stucco finish shaken off a browncoat brush--which might give a similar texture.  But, I could be remembering wrongly, too.

   Thanks Capn
   Not sure what you mean by shaking off a brush. This stuff actually looks like small pepple just onder the surface of the stucco....kind of BB sized. I'm in the high rockie Mtns of Colorado at about 7000 ft. Very dry....

   It's called a dash coat, where the wed mud stucco is applied and the pebbles are actually thrown against it to stick.  Another technique is to have a wet floated surface then dip a masons brush, or a broom, or we even used a green tree branch with several twig branches....this is dipped into a slurry of stucco and spattered onto the surface by hitting the stucco laden brush against a stick into the direction of the wall.  There are also texturing machines (popcorn) that spray the stucco on in various textures.  You have to play around with mud to get it to the texture you want.
