Does anyone know at what point you are no longer reaping much benefit from adding R-value to a wall or ceiling. At what R-value are you reaching the point of diminishing return? There was a previous post where it was stated that when spray foaming your boiler's storage tank you'd get little additional insulation value past three inches of foam. I thought maybe there's an analogous figure for wall and ceiling insulation, possibly dependent on how far north you are.
I will be framing and insulating my new boiler room hopefully shortly, as well as increasing ceiling insulation throughout the house so would appreciate any advice. I will probably spray foam my 1000 gallon tank too with the recommended three inches of foam, if I can find someone who will spray with high temperature rated foam.
