My next thing on the house I'm concerned about is the insulation. I know from doing HVAC that I want foam, but have any of you all ever done the whole house were they spray the bottom of your roof?. Getting quotes for the job. Some want to do all levels foam some for a cost savings are quoting flash and batt. Thats were they spray about 1 inch of foam then not fill the rest with fiberglass batt. Just wanting opinions?
