Insulation

Went by the house today and all of the insulation has been installed. They started over the weekend and I snapped a pic before they were done. I don't know much about insulation but I see they used R-13 for all the bag insulation which according to Home Depot is about as low as you would want to go for a wall framed in 2x4. I'm willing to bet that they will also blow in the minimum for this zone as well (R-30). I sort of forgot that they have to insulate over the garage since there is going to be a bedroom above there. I hope this means the garage won't get as hot (or cold LOL) as weather changes. Also with the hybrid water heater it should help with it not being so hot all the time. I only snapped one pic of their progress about halfway through.
