PART 3 - EXECUTION
3.1
Coordination
A.
All work by others which penetrates the roof,, interior or exterior walls shall be completed
before insulation subcontractor begins work.
B.
When dense-pack insulation process is on-going, Contractor shall minimize the work of other
trades in areas of dense-pack work.
3.2
INSTALLATION, GENERAL
A.
Examine substrates and conditions under which insulation work is to be performed. Do not
proceed with installation of insulation until unsatisfactory conditions have been corrected.
Clean substrates of substances that are harmful to insulation or vapor retarder, including
removal of projections which might puncture vapor retarders.
B.
Comply with insulation manufacturer's written instructions applicable to products and
application indicated.
C.
Install insulation that is undamaged, dry, and unsoiled and that has not been left exposed at any
time to ice, rain, and snow.
D.
Extend insulation in thicknesses indicated over entire area to be insulated. Cut and fit blanket
insulation tightly around obstructions, extend blown insulation around obstructions, and fill
voids with insulation. Remove projections which interfere with placement. Apply a single
layer of insulation of required thickness, unless otherwise indicated.
E.
Water-Piping Coordination: If water piping is located within insulated exterior walls,
coordinate location of piping to ensure that it is placed on warm side of insulation and insulation
encapsulates piping.
F.
For preformed insulating units, 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.

INSTALLATION OF RIGID INSULATION ON FROST WALLS AND UNDER SLABS
A.
On vertical surfaces of frost walls, temporarily set insulation units in place until interior back
fill is sufficient to hold insulation. Trim tops as required before installing insulation below slab.
1.
If not otherwise indicated, extend insulation down in 48 inch lengths.
B.
On horizontal surfaces, loosely lay insulation units according to manufacturer's written
instructions. Stagger end joints and tightly abut insulation units.
3.4
INSTALLATION OF LOOSE FILL CELLULOSIC INSULATION (Dense-Pack)
A.
3.5
MASTERSPEC -SHORT FORM
Apply blown-in cellulosic insulation according to manufacturer's printed 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.
INSTALLATION OF SPRAY IN PLACE LOW DENSITY FOAM INSULATION
1.
Installers: Experienced technicians trained and certified by the manufacturer for
installation of the product used.
2.
Apply at walls (including band joists) by factory certified technician according to the
manufacturer’s printed instructions.
3.
Examine substrate and conditions under which the spray insulation work is to be
performed, with Contractor present, and notify the Contractor of any unsatisfactory
conditions, including, but not necessarily limited, to:
a.
Excessive dirt or oil on substrate
b.
Excessive moisture present including dampness, dew, frost, or water.
4.
5.
6.
7.
8.
9.
Install insulation only when the temperature on both sides of the wall is a minimum of 40
deg F during foaming and for a forty-eight (48) hour period after foam has been placed in
the wall cavity. If the exterior temperatures are below 40 deg F, the interior temperature
must be at least 40 deg for a minimum of eight (8) hours prior to injection and forty eight
(48) hours after completion. In any case, the outside temperature must be above 20 deg F
unless the exterior wall is protected on the outside by thermal insulation, min R8.
During installation, provide a minimum two (2) air changes per hour ventilation for
installation personnel. Provide heat only through the use of vented heat sources with no
open flame.
Cover tools and work of other trades as required to prevent damage from overspray. Do
not weld or operate open flame tools of any kind near the installed product. Cover with
subsequent work as soon as possible.
Apply at walls (including band joists) by factory certified technician according to the
manufacturer’s printed instructions.
Protect installed insulation from exposure to weather and physical abuse. Provide
temporary covers for installed work that is not immediately concealed.

SECTION
A.
3.7
On vertical surfaces of exterior walls, apply square-edged 1” x 48” x 96” insulation units
horizontally (24” high) for top 48” of wall as indicated. Fasten using 2” galvanized Z channel,
attached to concrete wall according to manufacturer’s printed instructions. Secure top of top
insulation course using compatible sealant. Entire surface of insulation will be covered with
5/8” GWB, with perimeter of GWB and all penetrations sealed with low expanding foam
insulation.
INSTALLATION OF SPRAY IN PLACE LOW EXPANDING FOAM INSULATION
AROUND DOOR AND WINDOW FRAMES
A.
Install spray in place foam from canisters around door and window frames. Apply in single
bead to fully expand into space without compressing window or door frame. If expansion of
foam causes jamb to move, remove foam, re-shim and secure jamb, and repeat foam
installation.
B.
Insulate all cracks, penetrations, and voids in exterior sheathing.
