Gordon, They spray the walls with a glue of some sort and then push the insulation into it. It is a batt insulation, but not fiberglass. I'm not sure what it is made out of, but it almost felt like a wool product. They said it has a higher R rating than fiberglass but no formaldihide products in it. They admit that the aluminum framing has a zero R factor. It is actually a conductor. That may be why the top part of the walls feel different than the lower parts. More aluminum up high due to the framing of the walls and roof plates. The interior wall covering has a vapor barrier on both sides to stop the flow of moisture either way. That's 1 of the reasons why sometimes the inside windows will fog up when running the furnace. We always crack a window on the down wind side if possible. It makes for a slightly more comfortable atmosphere.
Their service area is not that large. Seems to be just several doors plus what they can do outside. They really could add on here and offer quicker service. That would really shorten the wait period.
