Technolog y
Insulation installed too close to
light xtures may affect the
luminaire’s performance. Do not
install insulation on top of or
within 3" of recessed light xtures
unless the xtures are approved
for such use. This is a requirement
of the National Electric Code.
Installation
Both FSK and PSK Flame Spread 25
insulation facing options are more
abuse-resistant than most other
building insulation facings.
However, when it is installed in
areas where the material may be
subject to abuse, suitable
protection should be provided.
Between Wood Studs
Flame Spread FSK and PSK 25
insulation should be t between
the studs with the anges stapled
to either the face or the side of
the stud every 8-12" to prevent
gaping or “ sh-mouthing” of the
vapor barrier.
Between Metal Studs
For most applications Flame Spread
25 insulation can be friction- t in
place until the interior nish is
applied. For applications where
extra support is desired, or when
applied in heights exceeding 8',
supplementary support should be
provided to hold the product in
place until the interior nish is
installed.
Exposed Masonry Walls
Flame Spread 25 insulation can be
applied by impaling on stick pins
or other similar attachments and
then af xing a locking washer on
the pin to hold the insulation in
place. Caps to cover the ends of
the pins should be speci ed for
areas where people may come
into contact with them.
Under Roof Decks
Flame Spread 25 insulation may
be wired, pinned or stapled into
position. Consult insulation
contractor for preferred
installation method.
Be sure to follow the stick pin
manufacturer’s recommendations
in regard to surface preparation
and attachment of the fastener to
the wall and under roof decks.
For wall and under roof deck
applications, the minimum
number of stick pins needed for
Flame Spread 25 insulation batts
and blankets in thicknesses up to
and including 6¼ " R-19 are shown
in Figure 1. Stick pins should be
placed 3-6" in from the edge(s) of
the product.
Product should be kept dry
during shipping, storage and
installation.
Applicable Standards
Flame Spread 25 FSK-faced
insulation complies with ASTM
C665, Type III, Class A. Flame
Spread 25 PSK (polypropylene-
scrim-kraft).
The thermal resistance values for
Flame Spread 25 insulation were
tested in accordance with ASTM
C518; R-value for insulation only.
The surface burning characteristics
of Flame Spread 25 insulation
were derived from product tests
per ASTM E84. This standard is
used solely to measure and
describe properties of products
in response to heat and ame
under controlled laboratory
conditions. These numerical
ratings are not intended to re ect
hazards presented by this or any
other material under actual re
conditions. Values are reported
to the nearest re rating.
The vapor retarder permeance
of the FSK facing on Flame
Spread 25 insulation was
developed from tests conducted
in accordance with ASTM E96,
desiccant method.
Flame Spread 25 insulation
contains ber glass wool, which is
a possible cancer hazard. To avoid
this possible cancer hazard,
minimize breathing ber glass
wool dust. Use a properly tted
NIOSH or MSHA approved
disposable dust respirator such as
the 3M model 8210 (Model 8271
in high humidity environments) or
equivalent when installing or
removing this product in poorly-
ventilated spaces such as attics or
crawlspaces.
Fiber Glass and Mold:
As manufactured, ber glass
insulation is resistant to mold
growth. However, mold growth
can occur on building materials,
including insulation, when it
becomes contaminated with
organic material and when water
is present. To avoid mold growth
on ber glass insulation, remove
any water that has accumulated
and correct or repair the source
of that water as soon as possible.
Insulation that has become wet
should be inspected for evidence
of residual moisture and
contamination, and any insulation
that is contaminated should be
promptly removed and replaced.
