I finished up a thermography inspection on an upper end home where practically every wall I scanned was missing insulation or simply in most cases not properly installed.
The floors and ceilings can easily be addressed however the home has 20 foot walls in some place and to cut out drywall and fix same would be rather expensive. I called numerous insulation contractors that I have used in the past but so far none have been able to advice me of a product that could be sprayed in with the least amount of wall repair needed.
One of the guys was telling me about possibly using Icynene however Im 99% sure that would create more problems as it expands…creating more pockets where it is pushing the insulation back.
Have been looking to see if their is more of a fine power type insulation that could be sprayed with a 1/2" nozzle.
Appreciate any suggestions
