My husband and I have completely gutted our first home, a 1920's craftsman on the NorthWest Missouri Plains. It is very windy on the Plains and we have some very cold winters. We are having a rough time deciding between Icynene and Blown in Blanket. The cost if the Blown in Blanket is going to be about $1000-$1500 less than the Icynene. We're getting mixed reviews on both. What would you choose and why?
