The Hi-R Wall System is a specially designed concrete masonry unit and individually molded insulation insert.

The block and the insulation are combined at the block manufacturing plant prior to delivery to the job site. The assembly provides a wall system capable of achieving higher thermal R-values than conventional masonry, with no effect on the structural integrity of masonry construction.

Insulation Inserts

Hi-R 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.

Masonry Units:

Korfil Hi-R masonry units are available in precision faced and decorative faced units. Unit sizes are available in 8, 10 and 12-inch with nominal 8 inch x 16 inch face dimensions as well as 4 inch x 16 inch face dimensions.

Applicable Standards:

  • ASTM C 578, Type X, replacing Federal Specifications HH-I-524C. Specification for Rigid Cellular Polystyrene Thermal Insulation.
  • ASTM C 90 Standard Specification for Load-bearing Concrete Masonry Units.
