Im air conditioning my garage and have already insulated the garage door. I need to do the attic but have a hip style roof and lots of trusses in the way which makes the corners and far edges almost impossible to get to. Home Depot lets you use the machine for free when you buy the blow in insulation. Seems like a much easier way to get to the hard to reach places. You can get the pink fiberglass blow in, or some eco friendly version. Anybody tried it before? Any thoughts?
