SECTION 07217

SLAB INSULATION UNDER BUILT-IN COOLER

PART 1:  GENERAL

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

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

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:

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.

PART 4:  MEASUREMENT AND PAYMENT

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.  Contractor shall include consideration for this item in the bid price for other items of the Contract.
