SECTION 07217

SLAB INSULATION UNDER BUILT-IN COOLER

[PART 1: GENERAL]{.underline}

1.1 SUMMARY:

A. Section Includes: Providing and installing rigid urethane insulation
board over a concrete base. A second concrete (floor) slab shall be
placed above the insulation.

1.2 REFERENCES:

A. American Society for Testing and Materials:

ASTM D 1621‑73 Test Method for Compressive Properties of Rigid Cellular
Plastics

ASTM D 1622‑88 Test Method for Apparent Density of Rigid Cellular
Plastics

B. International Conference of Building Officials (ICBO):

UBC-1991 Uniform Building Code

C. Underwriters\' Laboratories, Inc.:

UL 263-84 UL Standard for Safety Fire Tests of Building Construction and
Materials, Tenth Edition

1.3 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 5 copies of manufacturer\'s
current descriptive data, including insulating characteristics, and
instructions for protection of insulation to be used on this project.

C. Installation Instructions: Submit \[\_\_\] copies of the
manufacturer\'s installation instructions for insulation to be used on
this project.

D. Samples: Submit \[two\] 6 x 6 inch square samples of actual material
of insulation to be used on this project.

1.4 DELIVERY, STORAGE, AND HANDLING:

A. Delivery: Deliver materials to the site in the original sealed
containers or packages bearing the manufacturer\'s name and brand
designation. The containers or packages shall bear the referenced
specification number, type, and class as applicable. Inspect materials
delivered to the site for damage and unload and store with a minimum of
handling.

B. Storage: Storage spaces shall be dry locations permitting easy access
for inspection and handling. Store adhesive above 65 degrees F for 24 hr
prior to application. Urethane insulation is combustible. During storage
and installation, observe good fire safety practices, including job site
housekeeping.

[PART 2: PRODUCTS]{.underline}

2.1 MATERIALS:

A. Vapor Barrier: Six-mil polyethylene film or asphalt paper.

B. Insulation: Urethane rigid board with or without asphalt saturated
felt or foil‑kraft facers in 1-inch thickness. Boards shall meet or
exceed the following requirements:

1\. Compressive Strength in Thickness Direction according to ASTM D
1621, 25 psi

2\. Apparent Density according to ASTM D 1622, 2 pcf

3\. Surface Burning Characteristics according to ASTM E 84,

Flame Spread 45 maximum

Smoke Developed 160 maximum

[PART 3: EXECUTION:]{.underline}

3.1 EXAMINATION:

A. Verification of Conditions: Base concrete slab shall have the overall
dimensions required by the drawings and square. Insulation/floor slab
depression shall be sloped to drain and floated to a smooth surface.
Vertical walls shall be free of fins and other projections left after
removal of concrete forms All surfaces shall be dry and free of foreign
material.

3.2 PREPARATION:

A. Surface Preparation: Remove waxes, oily films and other residue left
on concrete surfaces from form release agents.

3.3 INSTALLATION:

A. General: Insulation shall be turned up 4 inches at perimeter (under
cooler walls).

B. Vapor Barrier: Lay sheet material in largest practicable width
continuously for the length of the depression and up vertical depression
walls. Lap edges 6 inches and seal with a permanent tape recommended by
vapor barrier manufacturer.

C. Insulation:

1\. Horizontal: Install first layer of insulation board tight to the
depression walls and to each other. Install second layer as above, but
stagger all joints 1/2 board width and length.

2\. Vertical: Install short vertical sections lengthwise of board.
Stagger end joints 1/2 board length. Top surface shall be flush with
finished concrete slab, bottom surface fits evenly and snugly with
horizontal insulation. Retain in place temporarily until concrete floor
slab is placed against it.

D. Placement of Floor Slab: Maintain in tight alignment during placing
of slab welded wire fabric reinforcement and during placement of
concrete floor slab.
