Block Insulation Inserts for Concrete Masonry Units
Basic Use: KORFIL Inserts are individually molded of expandable polystyrene and designed to fit standard two (2) core masonry units of 6, 8, 10 and 12-inch widths for use in both single wythe and cavity wall construction. Inserts are preinstalled at the block plant prior to delivery on the job site. In addition to nearly doubling the insulating characteristics of a masonry wall, KORFIL Inserts:
Limitations: Expanded polystyrene products of any type should not be exposed to temperatures in excess of 184�F.
KORFIL Inserts are made from flame-retardant treated expandable polystyrene. Like all foamed plastics, good fire procedures must be followed during storage and installation. Inserts give off no toxic products of combustion, except carbon monoxide and carbon dioxide, concentrations of which are far less than those given off by equal volumes of wood products. Expandable polystyrene contains no fluorocarbons and no formaldehyde.
Composition and Materials: KORFIL Inserts are individually molded from expandable polystyrene in a density range of 0.90 to 1.14 lbs. per cu. ft. Inserts are packaged at the point of manufacture in heat-sealed, clear polyethylene bags.
Technical Data: The Thermal Properties tables show the thermal resistance (Rt), including inside and outside air surface resistances of .68 and .17 hr-ft2-�F/BTU, respectively, and the U-values for various densities of concrete masonry units.
Physical Characteristics: See Physical Properties chart.
Preparatory Work: None required. Inserts are placed in blocks prior to delivery to the job site. Inserts do not affect the handling of blocks so no added labor is involved.
Precautions: During storage and installation, good fire safety procedures should be followed. Care should also be taken to make certain all broken or damaged inserts are replaced.
