Instructions / Assembly

3. Carefully run hands down along the edges of installed
insulation to ensure it is lling the back corners and/or is not
caught on any projections from the framing members.
Note: Care should be taken when working with metal studs. Edges and cutouts can
be sharp. Wear cut-resistant gloves when working with metal studs.
If there is any excess insulation at the bottom:
• Recheck for gap at the top of cavity. If there is a gap,
reposition the insulation.
If there is no gap, trim off excess to approximately ½ inch (longer
than cavity).
Note: Never fold the insulation to t in the cavity as this can create a crease/void
from side-to-side in the cavity.
FLOORS
Fiberglas™ insulation should friction t in 2x lumber joists and
trusses. For I-joists, Fiberglas™ insulation will sit on the bottom
ange. Fiberglas™ insulation must be full 16 inches or 24 inches
wide when used with I-joists.
1. Push insulation with just enough force to ensure it is fully
in the cavity but not compressed. Install each batt until the
length of the cavity is lled. Measure and cut the last piece
to t.
2. If needed, add wire ties to hold insulation in place until nish
ceiling is added. For crawl spaces, it is recommended to use
wire ties every 18-24 inches to ensure the batts stay in place
(no nish ceiling).
3. Acoustic applications do not require the cavity to be lled.
Since location of the batt in the cavity does not affect acoustic
performance, we recommend placing the batt at the bottom
of the cavity, so it can be supported by the nish ceiling.
ATTICS
1. Install baes as needed along sot to ensure ventilation path
along roof deck.
2. Start installation in areas farthest from the attic access, and
work back to attic access.
3. Full-width batts will butt together over framing if insulation is
taller than thickness of framing (e.g., trusses).
4. Leave 3 inches of space around non-IC rated light xtures.
Insulation can be in contact with and go over IC rated light
xtures.
GENERAL NOTES
• This product does not require a trained or certied installer.
• This product is classied as an “Article” under the
OSHA Hazard Communication Std. and does not require
a Safety Data Sheet. Copies of the Article Declaration Letter
and Safe Use Instruction Sheet (SUIS) are available on
www.OwensCorning.com.
• Protect from open ame or heat sources. Do not place
insulation within 3 inches of light xtures or similar electrical
devices unless labeled for contact with insulation (IC Rated).
Clearances around appliances, chimneys, and other hot
surfaces should meet the requirements of the National
Fire Protection Association (NFPA) and International Code
Council (ICC) building codes, or the appliance manufacturers’
recommendations. Use only unfaced insulation between wood
framing and masonry chimneys. Do not place insulation in air
spaces surrounding metal chimneys or replaces unless they
are designed to be in contact with insulation.
