Had not thought off that. In fact I have extra bats of insulation in the attic left over from covering the porch areas in the attic that were not insulated when the house was built. I'll get up in the attic today and try to do so. Only problem might be reaching the turbines as they are on the roof peak. I might have to use one of my extendable poles and attach the insulation to the end of the pole to reach the turbines. Thanks for the idea!When it is like this if you are able to do so you can get in the attic and push a section of fiberglass insulation up into the wind turbine hole.
This is as good as bagging it.
Easier to remove in the summer also.
