The Spec-Brik Hi-R units have been designed to provide reduced thermal bridging and can be used in both fully and partially grouted wall assemblies with no need to remove the insulation inserts for uncompromised thermal performance.
Hi-R Inserts are made by Concrete Block Insulating Systems, Inc. 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 more dense building construction products. Expandable polystyrene contains no fluorocarbons and no formaldehyde.
