APPROXIMATE INSULATION
THICKNESS:
Thickness of the insulating material generally
would indicate the R-value of the material. Each
material has its own characteristic measurement.
The inspector cannot ascertain the R-value of a
given material but you may consider 4 to 6
inches of insulating material, such as
fiberglass or cellulose loose fill as a minimal
acceptable amount. The inspector cannot
ascertain whether insulation exists within
walls, enclosed areas or under slabs. R-value is
defined as the measurement of the
"resistance to heat flow" of a given
material. The higher the R-value the better the
material is as a thermal insulator. Newer
buildings should have at least R-19 in the
attics and R-11 to R13 in the walls. In mild
climates an R-value greater than this is
exceptional. under floor insulation is usually
fiberglass batts which are either stapled or
wired to the underside of the flooring and
between the floor joists. Keep this material
securely fastened. It is not uncommon to see
this material hanging out of position.
Insulation will vary in thickness due to
installation variations, settlement and
compression by personnel or animal traffic.
