We recently purchased an brand new home in August and this is our
first year in the house. The house is much larger then my previous
house (3200 sqft vs 2400 sqft) and I've noticed that the furnace runs
much longer and much more often then my previous house. Based on the
specs of the builder, they put in R-11 batts in the ceiling with R-27
blow in "for tight insulation" and R-13 batts in the walls.
Does this sound sufficient? I'm not sure what the total R value would
be for the ceiling (do you add the R-11 and R-27 to come up with R-38)?
