Insulation, Radiant and Vapor Barriers - How do I insulate my exterior walls

I have a two story home and the basement brick goes up to the second story. Over the basement brick is Lannon stone up to the second story. My exterior walls are really cold. I took off the drywall and found no room for insulation. After you see the basement brick, there is a layer of tar paper, then 3/4 inch furring strip, then 2 pieces of drywall together as one. That's it!There is only a 3/4 in. air gap in the wall. One room I took off the drywall and added 3/4 in. furring strips to the existing 3/4 in. furring strips and put in 1 1/2 in. pink foam insulation in between then put new drywall on. I don't want to make any of the rooms smaller. If I did this to the whole house, I would have to pull off the kitchen cabinets etc. My question is....., is ther a different or better way to insulate. Is there a liquid foam product that I can put a hole in the wall at the top and insert a long wand to the bottom and work my way up? But the foam can't be expanding foam that it blows out the existing drywall.I need help and answers.

Is your objective to have warm walls or to control heat transfer through the walls? We have used a multi-ceramic insulation coating to control heat transfer through the exterior walls and ceilings with good results. In other words, there was less heat loss thus lower utility usage. It does not warm the walls rather it repels the heat away from the walls where the coating is applied.

Foams and fibreglass "slows" heat transfer but never actually blocks it. Heat is absorbed into these products which through pockets of air slows heat from escaping. When I say escaping I am referring to simple thermal dynamics. Warm air molecules always move towards the cold.

With this in mind think about what is actually happening when you insulate your house this way. Heat is transferring through the walls/ceilings into the insulation and ultimately to the outside. How much and how fast depends upon the thickness and quality of your insulation. We have become conditioned to believe that the most effective insulation must be thicker. This method of insulating will trap and hold heat for a period of time but never actually stop it from transfering through the substrate altogether.

The multi-ceramic insulation coating does not take on heat at all rather it repells it away. Therefore on interior applications it will contain heat more effectively as the heat cannot flow through the insulation material, on exterior applications it will repel heat which is ideal in the summer months. This is the only insulation I have found that actually addresses all three forms of heat transfer (convection,conduction and radiation). All of the other insulations only address one or two.

One other word of caution, do your homework. Allways look for the ASTM certifications that proves the product will perform as claimed. I have found one which is actually listed as an insulation. It is fully supported with numerous ASTM certifications including ASTM C-236 which compares it to R-19 Fiberglass.

A distributor in Western Washington has been conducting an ongoing test on his own house with the local utility company to determine first hand how effective this insulation is during the winter months. I am waiting patiently for those results. Apparently there is a lot of data on commercial buildings but little on residential as this product was designed initially for the commercial industry.
