When it was all said and done, 2 1/2 to 3 inches of closed-cell insulation was blown onto both the walls and the ceiling. After that, over a foot of open-cell insulation was blown onto the roof rafters, for a combined value of R55. This will help to keep the house warm in the winter, and cool in the summer.
The company also put rock wool insulation along all of the bathroom walls to minimize noise within the house. (And yes, I had to ask Joe for all of this information… it just looked to me like a bunch of Marshmallow Fluff all over the walls and ceilings.)
When another sub-contractor came by after the insulation was blown in, he said, “oh, this is really good insulation”, which made me happy!
