A Berkshire Hathaway Company
Safety glasses with side shields are recommended to keep dust out of the eyes. Use ear protection
(earplugs, hood, or earmuffs) to prevent airborne dust or ﬁbers from entering the ear, if necessary.
Leather or cotton gloves should be worn to protect against mechanical abrasion. Optional: wear a
NIOSH-certiﬁed disposable or reusable particulate respirator with efﬁciency rating of N95 or higher
(per 42 CFR 84) except required when dust or ﬁber concentrations exceed the applicable exposure
limits of dust 15 mg/m
. Wear a cap, a loose-ﬁtting, long-sleeved shirt and long pants to protect skin
from irritation. Exposed skin areas should be washed with soap and water after handling or working
with ﬁber glass.
Other trades, including but not limited to, electrical, plumbing, and mechanical should have already
installed their required materials prior to the ﬁber glass being installed. Proper air sealing should
be complete prior to ﬁber glass batt installation to insure full performance of the ﬁber glass batts.
Verify all holes and seams between sheet goods such as drywall, sheathing, and subﬂooring at the
building envelope are sealed with durable caulk, tape, and/or foam sealants.

Johns Manville ﬁber glass batt and roll insulation is easy to install and does not require a certiﬁed
installer. Wherever insulation is installed in a building, it is very important that it ﬁts snugly on all
sides. If the insulation is too long for a space, cut it to the correct size. If it is too short, cut a piece
to ﬁll the void. For unfaced batts, friction ﬁt it into the cavities. If using faced batts, they may in
friction ﬁt or the ﬂanges may be stapled to the wood studs. Use a Bostitch, Arrow or similar manual
staple gun and
" staples, using enough staples to hold the insulation ﬁrmly in place and
avoid gaps and ﬁshmouths.
