Are SIPs susceptible to insects?

Although termites do not feed on the foam panel cores, there have been instances where panel cores have been hollowed out by these insects and used as a nesting ground. To prevent this, many manufacturers offer SIPs with borate-treated foam. Termites may also be deterred through the use of a specially 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.
