I'm doing a complete renovation on my 3 story home in Lake Tahoe. I've narrowed it down between two insulation bids.

One option is using Certainteed Optima Blow-In Insulation on all exterior walls using a vapor barrier to give me R 23. Also using it on several interior walls with quiet rock to help with sound and he wants to use R30 unfaced batts on the between floor sound insulation. I have no attic, and for various reasons I have to use l.5" rigid insulation on my ceilings which only gives me R 9.

My other option is Johns Manville Spider Wall Spray on my exterior walls using visqueen vapor barrier. This is supposed to give R 22 but supposedly better with sound insulation on the interior walls. Same R-30 batt recommended on the between floor ceilings.

I'm leaning toward the Certainteed Optima Blow-In. Has anyone used either of these products and have any opinion one way or the other?
