On Friday the insulation installation was complete.   WOW that’s a hole lot of insulation.   Well insulation is key to the performance of a high performance house. It both help seal and does the insulation.  Ken packed in extra tight the cellulous into the corners and areas we suspected leaks.  Packing the cellulous tight lowers the R-Value a little but resists leaks .   Here are some phots of the house with the insulation done. Remember the cavity between the back of the sheathing and the drywall is 10″ .   The house really holds it temperature.
