Abstract

A prefabricated building panel, sometimes referred to as a stress skin panel, having a core which may be comprised of a single layer or may have multiple layers of material and into which core is incorporated, or encapsulated, borates in the form of borate compounds similar to TIM-BOR® in an amount (typically between about 2 weight percent and about 10 weight percent) which results in a core material which deters the entry of and the infestation of ants and other insects thereby enhancing and improving the usefulness of such prefabricated building panels. The addition of the borate compound has also been found to act as a fungicide and further flame retardant properties of the building panel are improved. Borate may be added, if possible, into the core material of any known prefabricated construction/building panel. However, it is most advantageous and effective if the borate is added during the fabrication of the core of the panel.
