Insulation in a stucco home...

Our house in VERY cold. It is a 50 yr old stucco house, with plaster walled interior. The house is very cold, even with the digital thermometer set at 72.
What is the best way to insulate the home???
I have been told either side the house (do not want to change the look of the home) or blow insulation in the walls (what is the procedure and cost involved??

Thanks....frostbite Mike

Economically, insulation starts in the attic. R-values can be calculated here:

Next on the list would be walls. Then floor/crawlspace.

There is a balance between the cost of adding insulation incrementally and the return on investment. For instance, if might not be economically feasible to add more insulation to increase R -38 to R-49. It may be that it would take 20 years to recover the cost. If the walls were uninsulated, their insulation might make more sense. That return may come in fewer years, making more sense.

Much of this depends upon your current insulation. If you discover that you have R-19 in the attic, six inches of insulation, then moving toward the recommended level can make a lot of sense. If your area recommends R-49, there is a lot of difference between R-19 and R-49. Increasing the attic insulation would be a wiser move than insulating the walls before the attic.

Blowing insulation into walls seems to be the best way to insulate existing walls. A hole is cut into the wall between the studs, for each space between studs and insulation is blown into the cavity. The hole is then repaired.

Hope this helps.
