The Right Way To Insulate CertaSpray Spray Foam Insulation

[HomeEnergyNow]

Right way to insulate? Walls have 2 required air barriers, you think they need a third? The leakiest places in a home are windows/doors/bottom plate/bathroom vents/fireplaces, none of which see spray foam.The tightest home I have tested was .01 ACH, w/out spray foam. No spray foam can achieve R-60, but for less money you can with loosefills. Add the cost of spray foam, add the cost of now having to bring in fresh air, add the cost of higher energy bills compared w/R-60, add risk of no fresh air
