Going to R-49 is a lot of insulation and they used fiberglass, not rock wool. They also installed batt insulation on the ends of the house which were just bare wood and soffit vent deflectors on all the soffit vents. It was $5000 for a 2100 sq ft house. If you rent a machine you need to get a full body suit with eye protection and a respirator. The two guys that went in the attic were all suited up and you have to have another person feeding the machine. Also I have a very long house and it took about 150 ft of hose to reach the back of the house from the machine through the attic access. I check my daily electric usage with OG&E Energy Insights and my usage is gown 25-30% compared to comparable weather days of 90 degrees and above before the insulation.
