Spray insulation seems to run up to 3 times what batt insulation costs. To use or not to use depends on your weather conditions. I did not use it and found that the extreme wind conditions here (plains) would have warranted it's use. Did use house wrap and foamed around windows and doors but still get wind leaks. Guess extreme hot or cold would also be a good reason.

There is definitely a higher front end cost, but investment pays.

Every client I have built for with this ionsualtion has been glad to carry that cost and to own the product and live with it.

Another advantage is that it makes the home muc quieter too.

But pay attention to ceiling and perimeter sills also. by doing the whole package, you control infiltration rates which are a large part of the heating /comfort cost equation.

Excellence is its own reward!
