Insulation - I am assuming that this is more than buying some R-19 and stuffing it into the house?
Client brought in receipts, but does it meet International Energy Conservation Code (IECC) that I'm reading about in the Form 5695 instructions? "You can rely on the manufacturer's certification" So, products that qualify have a certificate? (Windows I know only need a Energy Star sticker - I am wondering about things in IECC category like insulation.)
R-19 sounds very impressive, but is it good enough?
