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.
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.
