air seal attic with spray foam - www.startinsulating.com

@ivcruiser Which cost return calculator did you use? If you don't know the cost of the material, or the cost of the electricity/gas, or the efficiency of the HVAC, than you can't say shit about cost return can you? 23 years you should probably know better huh?. Those three factors are just the main three in calculating ROI, why would even start to comment w/out those facts? And how can you call yourself a professional after that?

@ivcruiser R49-R60 is Energy Star for New England. High R value doesn't replace good air sealing, though- they go together.

See the link I just posted. I rest my case that R60 is a cost effective choice. Maybe it is time for you to retire.

The house had 5 inches of loose fill fiberglass. That stuff has an R value of about 2, so the total existing was about R10. Nothing wrong with going to R60, especially when you are doing the work yourself and buying cellulose in bulk (950 bags at a time). And my buddy who has been in the business 3 years has put a few of the local competitors who have been in the business 20-30 years OUT of the business.

depending on the age of the house there may NOT have been any building inspectors around at the time! ..Also, i am not sure where the guy speaking in this video got his info but 10" of cellulose over a R19 batt is closer to a R59 NOT a R40, the owner who did it himself wasted alot of cash on going that deep, speaking from 23 yrs experiance.

I should add that spray foam is an excellent way to seal up ceiling penetrations, like lighting fixture boxes and openings in wall plates for plumbing vent pipes, but a reliable contractor should have been called in to install fire stopping before proceeding with the insulation.

Makes you wonder how that house was approved by the building inspector at the time it was built! It needs a lot more than spray foam to correct the numerous fire paths into the attic.
