PART 2  -  PRODUCTS

	
       2.01	ACCEPTABLE MANUFACTURERS
		
		A.	Manufacturers of Foamed-In-Place Masonry Insulation:  Subject to compliance with 				requirements, provide products from the following:

			1.	Thermco™  Thermal Corporation of America, 1405 West Washington,	 					Mt. Pleasant, IA  52641  (319) 385-1535
       
       			No substitutions allowed.

	2.02	INSULATING MATERIALS

A.	General:  Provide insulating materials which comply with requirements indicated for materials, compliance with referenced standards, and other characteristics.

B.	Foamed-In-Place Masonry Insulation:  Two component thermal insulation produced by combining a plastic resin and catalyst foaming agent surfactant which, when properly ratioed and mixed, together with compressed air produce a cold-setting foam insulation in the hollow cores of hollow unit masonry walls.

              1.	Fire-Resistance Ratings:  Minimum four (4) hour fire resistance wall rating 				(ASTM E-119)  for concrete masonry units when used in standard 					 two (2) hour rated CMUs.  

			2.	Surface Burning Characteristics:  Maximum flame spread, smoke developed and 				fuel contributed of 5, 50-100, and 0 respectively.	 																
3.	Combustion Characteristics:  Must be noncombustible, Class A building material. A Class A building material must have a flame spread rating of 25 or less.

       4.	Thermal Values:  "R" Value of 4.7/ inch @ 35 degrees F mean; ASTM C-177.  		
5.	Sound Abatement:  Minimum Sound Transmission Class ("STC") rating of 54 for 12” CMU and 52 for 8” CMU.

									
PART 3  -  EXECUTION
	
3.01	INSPECTION AND PREPARATION

		A.	Application Assemblies: 

			Block Walls:	   6", 8", 10" or 12" concrete masonry units

			Cavity Walls:	   2" cavity or greater

	3.02	INSTALLATION OF FOAMED-IN-PLACE INSULATION

A.	General:  Install foamed-in-place insulation from interior, or as specified, prior to installation of interior finish work and after all masonry and structural concrete work is in place; comply with manufacturer's instructions.

B. Examination: Examine walls and cavitis to determine whetehr there are conditions that would adversly affect the performance of the insulation. The walls to be insulated must be free of moisture both inside and outside of the block. Insulation is not to be injected into wet walls.

C. Installation:  Fill all open cells and voids in hollow concrete masonry walls where shown on drawings.  The foam insulation shall be pressure injected through a series of  5/8" to 7/8" holes drilled into every vertical column of block cells (every 8" on center) beginning at an approximate height of  four (4) feet from finished floor level.  Repeat this procedure at an approximate height of  ten (10) feet above the first horizontal row of holes (or as needed) until the void is completely filled.  Patch holes with mortar and score to resemble existing surface. 

D. Sampling:  Verify insulation density by random sampling. One cubic foot of fresh foam shall weigh between 2 lbs.8oz. and 3 lbs.6oz.

E. Painting: Allow two weeks after foam installation before painting masonry walls.
