or basement. The structural elements are usually exposed in these areas,
which makes it easy to see what type of insulation you have and to measure
its depth or thickness (inches).
Inspect the exterior walls using an electrical outlet:
Turn off the power to the outlet.
Remove the outlet cover and shine a flashlight into the crack around the
outlet box. You should be able to see if there is insulation in the wall
and possibly how thick it is.

walls. If so, the insulation in these spaces won't be visible. The builder
