PART 3 -EXECUTION
3.1 EXAMINATION
A.Examine substrates and conditions, with Installer present, for compliance with
requirements of Sections in which substrates and related work are specified
and for other conditions affecting performance.
1.Proceed with installation only after unsatisfactory conditions have been
corrected.
3.2 PREPARATION
A.Clean substrates of substances harmful to insulation or vapor retarders,
including removing projections capable of puncturing vapor retarders or of
interfering with insulation attachment.
3.3 INSTALLATION, GENERAL
A.Comply with insulation manufacturer's written instructions applicable to
products and application indicated.
B.Install insulation that is undamaged, dry, and unsoiled and that has not been
left exposed at any time to ice, rain, and snow.
C.Extend insulation in thickness indicated to envelop entire area to be insulated.
Cut and fit tightly around obstructions and fill voids with insulation. Remove
projections that interfere with placement.
3.4 INSTALLATION OF CLOSED CELL FOAM INSULATION (Basement Walls)
A.Apply insulation in continuous thickness from base of foundation wall to
underside of wood sub-floor.
B.Mask around existing windows and keep insulation clear of sash and frame.
C.Maintain clearances around vents and thru-wall penetrations for mechanical
equipment as recommended by equipment manufacturer.

3.5 INSTALLATION OF GENERAL BUILDING INSULATION
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.Place loose-fill insulation into spaces indicated, by machine blowing, to
comply with ASTM C 1015. 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 the Cellulose
Insulation Manufacturers Association's Special Report #3, "Standard
Practice for Installing Cellulose Insulation."
C.Apply self-supported, spray-applied cellulosic insulation according to
manufacturer's written instructions. Do not apply insulation until installation
of pipes, ducts, conduits, wiring, and electrical outlets in walls is completed
and windows, electrical boxes, and other items not indicated to receive
insulation are masked. After insulation is applied, make it flush with face of
studs by using method recommended by insulation manufacturer.
3.6 INSTALLATION OF INSULATION IN CEILINGS FOR SOUND ATTENUATION
A.Install loose filled cellulosic insulation in floor cavities above existing ceilings.
