# PART 3 - EXECUTION

## 3.01 [Examination]{.underline}

A. [Verify that conditions]{.underline} conform to requirements of
Contract documents.

B. [Verify that related work]{.underline} to be performed within
indicated spaces before installation of insulation has been completed.

C. [Verify that substrates]{.underline} are in satisfactory condition to
receive insulation.

[Masonry Substrates]{.underline}: Verify that masonry materials have
dried sufficiently and have attained optimum moisture content.

D. [Do not proceed]{.underline} until unsatisfactory conditions have
been corrected. Commencement of installation indicates acceptance of
conditions.

## 3.02 [Preparation]{.underline}

A. [Clean substrates]{.underline} of any substances which might damage
materials to be installed.

B. [Remove harmful projections]{.underline} capable of puncturing vapor
retarder.

## 3.03 [Installation]{.underline}

A. [Do not install]{.underline} insulation which is damaged, wet,
soiled, or which has been covered at any time with ice or snow.

B. [Comply with insulation manufacturer's]{.underline} recommendations
and installation sequence. Provide permanent placement and support of
insulation.

C. [Install materials]{.underline} in a manner which will maximize
continuity of thermal envelope. Use a single layer of insulation
wherever possible to achieve indicated requirements, unless otherwise
indicated.

D. [Insulation Boards:]{.underline}

1\. Cut insulation neatly as required to fit tightly around
obstructions.

2\. Install boards as indicated. Butt board edges and ends tightly. Form
solid joints where insulation boards meet protrusions and between
adjacent boards. Stagger joints.

3\. Foamed plastic insulation: Mechanically attach to substrate.
Coordinate installation as necessary with work specified elsewhere to
ensure that insulation is concealed promptly after installation.

4\. Extruded polystyrene insulation:

Foundation installation: Provide installation capable of sustaining
subsequent construction work without damage or displacement.

E. [Insulation Blankets/Batts]{.underline}:

1\. Install properly sized blankets/batts per manufacturer's
recommendations.

2\. Cut insulation neatly as required to fit tightly around
obstructions.

3\. Faced insulation: Place insulation with facing oriented toward warm
side of construction, unless otherwise indicated. Maintain ventilation
spaces. If tears or punctures occur, repair them immediately using
suitable procedures to restore integrity of membrane.

4\. Tape seal joints in facing with white vinyl tape.

F. [Vapor Retarder]{.underline}:

1\. Comply with membrane manufacturer's recommendations for installation
of membrane as vapor retarder in application indicated.

2\. Install vapor retarder in a manner which will maximize continuity of
protection against vapor transmission. Extend membrane tightly and
uniformly to building framing and to other objects (pipes, electrical
boxes, etc.) impinging on the plane of the membrane.

3\. Install vapor retarder on warm side of insulation unless otherwise
indicated.

4\. Locate membrane joints over framing members or solid substrates.
Seal overlapping joints, butt joints, and fastener penetrations.

5\. If tears or punctures occur, repair them immediately using suitable
procedures to restore integrity of membrane.

6\. Tape seal joints with white vinyl tape.

## 3.04 [Protection]{.underline}

A. [Protect installed materials]{.underline} from damage until permanent
concealing work is completed.

B. [Where concealing work]{.underline} is not performed immediately
after installation work of this section is completed, erect suitable
temporary coverings or enclosures to prevent damage.
