Are structural insulated panels susceptible to insects?
Although termites do not feed on the foam panel cores, there have been instances in which panel cores have been hollowed out by these insects and used as a nesting ground. Many manufacturers offer SIPs with borate treated foam to provide termite resistance. Termites may also be deterred through the use of a specifically designed steel mesh. Both these treatments are highly effective, but they are not a substitute for careful termite prevention and maintenance, as with any other wood structure.
