Insulated Concrete Blocks
To add comfort to your building, consider insulating your block. National Block offers Korfil block insulation as well as ICON Universal Inserts for concrete masonry units. Contact National Block today for more information or to place your order!
Korfil Block Insulation
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:
- Eliminate the need for on-site labor to insulate masonry walls.
- Do not deteriorate in insulation R-value with moisture or aging.
- Allow space within the cores for the escape of moisture. This space also allows for easy installation of utilities within the wall.
- Can be handled by masons just as easily as uninsulated blocks.
- Are cost-competitive when compared to the various other methods used to insulate concrete blocks.
- Have no effect on the fire rating of conventional concrete block walls.
- Improve both the dewpoint and sound transmission resistance of ordinary concrete blocks.
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.
ICON Universal Inserts for Concrete Masonry Units
Basic Use: ICON Inserts are molded from expandable polystyrene. The design of the insert allows it to compress so it will fit the cores of all masonry units with just one size. Inserts are placed in the cores of the block at the block plant. By placing inserts in blocks, there is a significant improvement in the thermal efficiency of masonry walls.
Product Advantages: ICON Insulated Blocks:
- Eliminate the need for on-site labor to insulate masonry walls.
- Insulation R-value does not deteriorate with moisture or aging.
- Allow space within the cores for the escape of moisture. This space also allows for easy installation of utilities within the wall.
- Can be handled by masons just as easily as uninsulated blocks.
- Are cost-competitive when compared to the various other methods used to insulate concrete blocks.
- Have no effect on the fire rating of conventional concrete block walls.
- Improve both the dewpoint and sound transmission resistance of ordinary concrete blocks.
