The answer
depends on a number of factors:
- Where
you live — you’ll need a higher R-value
if you live in the Northeast than if you live in Southern California.
- The age of your home (if your home is more
than 10 years old, you likely need more)
- How your home is built — for example,
is it a single-level or multi-level structure? Do you have cathedral
ceilings? Is there a basement or is your home built on a slab?
- How you heat and cool your home —
do you have a furnace, a central air conditioner, or a heat
pump?
