1.03 SUBMITTALS:

A. General: Submittals shall be according to \[Section 01009 - General
Information and Requirements.\] \[and\] \[Section 01300 - Submittals.\]
\[and\] \[Section 01365 - Certificates of Conformance.\]

B. Manufacturer\'s Literature: Submit \[[ ]{.underline}\] copies of the
manufacturer\'s descriptive data including the insulating
characteristics for the insulation to be used on this project.

C. Installation Instructions: Submit \[[ ]{.underline}\] copies of the
manufacturer\'s installation instructions for the insulation to be used

D. Samples: Submit \[two\] samples of the insulation to be used on this
project. Samples shall be 6- by 6-inch squares.

1.4 DELIVERY, STORAGE, AND HANDLING:

A. Storage: Materials shall be kept dry and at a location remote from
construction activities, and permitting easy access for inspection and
handling.

[PART 2: PRODUCTS]{.underline}

2.1 MATERIALS:

A. Rigid Foam Insulation: One inch reflective foil‑faced glass fiber
reinforced polyisocyanurate foam plastic core in plain factory finish.
Boards shall meet or exceed the following requirements:

1\. R‑value (aged) @ 75 degrees F mean temperature (ASTM C 236) ‑ 7.2

2\. Density (ASTM D 1622) ‑ nominal 2 pcf

3\. Compressive strength in thickness direction (ASTM D 1621) ‑ 25 psi

4\. Dimensional stability (ASTM D 2126) ‑ less than 1% change

5\. ab Coefficient of linear thermal expansion (ASTM D 696) ‑ 0.000013
in/in

6\. Flexural strength (ASTM C 203) ‑ more than 40 psi

7\. Water vapor transmission (ASTM E 96) ‑ less than 0.03 perms

8\. Liquid water absorption (ASTM C 272) ‑ 0.3% max.

9\. Flame Spread (ASTM E 84) ‑ 25 max.

B. Tape: Two‑inch wide regular duct tape used to hold insulation in
place to furring strips until gypsum board can be erected.

[PART 3: EXECUTION]{.underline}

3.1 PREPARATION:

A. General: Masonry and wall surfaces to receive insulation shall be
plumb, clean, dry, smooth, and free from foreign material. Masonry
joints shall be tool compacted and filled flush. Check surfaces for
protruding mortar or other obstacles that may interfere with the
installation. Remove such obstacles before insulation is applied.

B. New Construction: Masonry surfaces to receive insulation shall be
plumb, dry, smooth, and free from foreign material. Masonry joints shall
be tool compacted and filled flush.

C. Retro-fir Installation: Wall surfaces against which insulation shall
be applied shall be clean and dry. Check surfaces for protruding mortar
or other obstacles that may interfere with the insulation installation.
Remove such obstacles, if present, before insulation is applied.

3.2 INSTALLATION:

A. Furring Strips: Attach wood furring strips (net 1‑1/2 inch x 1‑1/2
inch) vertically to masonry wall 16 inches oc and continuously at floor
and ceiling junctures to receive mechanical fasteners to secure gypsum
board facing. Also provide furring strips where required, for subsequent
attachment of moldings, trims, cabinets or other heavy wall‑mounted
fixtures.

B. Insulation: Install insulation boards in a tight, snug fit to furring
strips in maximum lengths available. Butt ends shall be taped. Tape
edges to furring strips sufficiently to retain boards in place until
gypsum board covering can be applied. See Section 09260 ‑ Gypsum Board
Systems.

3.3 FIELD QUALITY CONTROL:

A. Inspection: Do not apply gypsum board until insulation installation
has been inspected and approved. Any insulation covered before
inspection shall be uncovered and recovered at Contractor\'s expense.

[PART 4: MEASUREMENT AND PAYMENT]{.underline}

4.1 METHOD OF MEASUREMENT:

A. Units: The work described in this section will not be measured for
payment.

4.2 BASIS OF PAYMENT:

A. Payment: No direct payment for the work described under this section
will be made. The Contractor shall include consideration for this item
in the bid price for other items of the Contract.
