PART 3 - EXECUTION
3.1 PREPARATION
A. Clean substrates of substances that are harmful to insulation or vapor retarders, including
removing projections capable of puncturing vapor retarders, or that interfere with insulation
attachment.
3.2 INSTALLATION, GENERAL
A. Comply with insulation manufacturer's written instructions applicable to products and
applications indicated.
B. Install insulation that is undamaged, dry, and unsoiled and that has not been left exposed to ice,
rain, or snow at any time.
C. Extend insulation to envelop entire area to be insulated. Cut and fit tightly around obstructions
and fill voids with insulation. Remove projections that interfere with placement.
D. Provide sizes to fit applications indicated and selected from manufacturer's standard
thicknesses, widths, and lengths. Apply single layer of insulation units to produce thickness
indicated unless multiple layers are otherwise shown or required to make up total thickness.
3.3 INSTALLATION OF BELOW-GRADE INSULATION
A. On vertical footing and foundation wall surfaces, set insulation units loosely laid according to
manufacturer's written instructions.
1. If not otherwise indicated, extend insulation a minimum of 36 inches (915 mm) below
exterior grade line.
B. On horizontal surfaces under slabs, loosely lay insulation units according to manufacturer's
written instructions. Stagger end joints and tightly abut insulation units.
1. If not otherwise indicated, extend insulation a minimum of 24 inches (610 mm) in from
exterior walls.
3.4 INSTALLATION OF INSULATION FOR FRAMED CONSTRUCTION
A. Apply insulation units to substrates by method indicated, complying with manufacturer's written
instructions. If no specific method is indicated, bond units to substrate with adhesive or use
mechanical anchorage to provide permanent placement and support of units.
B. Foam-Plastic Board Insulation: Seal joints between units by applying adhesive, mastic, or
sealant to edges of each unit to form a tight seal as units are shoved into place. Fill voids in
completed installation with adhesive, mastic, or sealant as recommended by insulation
manufacturer.

BUILDING INSULATION 07210 - 4
C. Glass-Fiber or Mineral-Wool Blanket Insulation: Install in cavities formed by framing members
according to the following requirements:
1. Use insulation widths and lengths that fill the cavities formed by framing members. If
more than one length is required to fill the cavities, provide lengths that will produce a
snug fit between ends.
2. Place insulation in cavities formed by framing members to produce a friction fit between
edges of insulation and adjoining framing members.
3. Maintain 3-inch (76-mm) clearance of insulation around recessed lighting fixtures not
rated for or protected from contact with insulation.
4. Install eave ventilation troughs between roof framing members in insulated attic spaces at
vented eaves.
5. For wood-framed construction, install blankets according to ASTM C 1320 and as follows:
a. With faced blankets having stapling flanges, secure insulation by inset, stapling
flanges to sides of framing members.
b. With faced blankets having stapling flanges, lap blanket flange over flange of
adjacent blanket to maintain continuity of vapor retarder once finish material is
installed over it.
6. Vapor-Retarder-Faced Blankets: Tape joints and ruptures in vapor-retarder facings, and
seal each continuous area of insulation to ensure airtight installation.
a. Exterior Walls: Set units with facing placed toward interior of construction.
D. Loose-Fill Insulation: Apply according to ASTM C 1015 and manufacturer's written instructions.
Level horizontal applications to uniform thickness as indicated, lightly settle to uniform density,
but do not compact excessively.
1. For cellulosic-fiber loose-fill insulation, comply with CIMA's Bulletin #2, "Standard
Practice for Installing Cellulose Insulation."
E. Miscellaneous Voids: Install insulation in miscellaneous voids and cavity spaces where
required to prevent gaps in insulation using the following materials:
1. Loose-Fill Insulation: Compact to approximately 40 percent of normal maximum volume
equaling a density of approximately 2.5 lb/cu. ft. (40 kg/cu. m).
3.5 INSTALLATION OF INSULATION IN CEILINGS FOR SOUND ATTENUATION

insulation over entire ceiling area in thicknesses indicated. Extend insulation 48 inches (1219
mm) up either side of partitions.
3.6 INSTALLATION OF VAPOR RETARDERS
A. Place vapor retarders on side of construction indicated on Drawings. Extend vapor retarders to
extremities of areas to protect from vapor transmission. Secure vapor retarders in place with
adhesives or other anchorage system as indicated. Extend vapor retarders to cover
miscellaneous voids in insulated substrates, including those filled with loose-fiber insulation.
B. Seal vertical joints in vapor retarders over framing by lapping no fewer than two studs.

wall openings; and at lap joints. Space fasteners 16 inches (406 mm) o.c.
C. Seal joints caused by pipes, conduits, electrical boxes, and similar items penetrating vapor
retarders with vapor-retarder tape to create an airtight seal between penetrating objects and
vapor retarders.
D. Repair tears or punctures in vapor retarders immediately before concealment by other work.
Cover with vapor-retarder tape or another layer of vapor retarders.
3.7 PROTECTION
A. Protect installed insulation and vapor retarders from damage due to harmful weather exposures,
physical abuse, and other causes. Provide temporary coverings or enclosures where insulation
is subject to abuse and cannot be concealed and protected by permanent construction
immediately after installation.
