Comments from Kurt
"Some walls are impossible to insulate." "That is what our homeowner was told.
These walls are constructed as follows -- exterior concrete block for structure. Then 2x4 framing with tongue-and-groove knotty pine interior.
With nothing but air space, these walls are cold in winter.
We have used many types of insulating materials in the past: Cellulose, Fiberglass, Poly, Air Krete; and we prefer the product Retro-foam. It is the most "green" of all the foam products and has the finest insulating characteristics. We use this in walls, closed spaces, attics, concrete block, between floors, and cathedral ceilings.
As you can see from the block-fill pictures, the foam will find its way into all of the cracks (where previously air had entered the home). To finish a block fill, we clean the wall and mortar our drilled holes.
The interior fill required some carpentry. To fill a wall such as this, a larger hole must be drilled in order to insure complete success. We snapped a line, drilled, filled, stained some bigger trim and custom fit it for the room.
Taking into consideration the limited efficiency of the concrete surrounding our foam and the bridge conduction of framing members of the wall, the new estimated insulation rating of the entire wall space exceeds R-35 (with little to no air infiltration).
We love it when we can make an old home outperform a new one. Pay attention builders."
