BATT OR BLANKET TYPE
INSULATION:
Batt type insulation consists of flexible strips
of insulation in pre-cut widths and lengths. It
is designed to fit between structural members,
such as, rafters or joists. Batts may be faced
with paper or foil, or may be unfaced. Usually
it is stapled in place, but may be held in place
by friction against the structural members on
either side. There are two common batt
materials. Fiberglass and rock wool. Fiberglass
is a material which is made of long filaments of
spun glass which are loosely woven into a sort
of mat. There is evidence that inhaled
fiberglass may cause lung cancer so be sure to
wear a proper respirator when in the vicinity of
this material. Blanket type insulation is the
same as batt type insulation but comes in rolls
which are not pre-cut to any particular length.
Rock wool is a material which is made of granite
rock or furnace slag which is melted at
temperatures up to 3000 degrees F. This material
is a good insulation material but has less
insulation value than many other materials. It
looks and feels quite like fiberglass but is
darker in color. Be aware that the inspector
cannot review or report on conditions that are
not visible. Insulation covering parts of truss
systems and other framing members prevents total
review of the structural integrity of the
building. Truss clips, hurricane ties and other
important anchoring devices often cannot be seen
by the inspector due to insulation. Contact the
inspector for additional information concerning
this inspection limitation if you desire.
