For structures in high humidity environments, or where there is a proliferation of wood-boring insects, Designer Doors recommends our High Humidity/Insect Resistant Package for extra wood protection.

We implant highly effective, EPA-approved Borate Rods into the door frame, reducing the possibility of damage from fungus, termites, carpenter ants, a variety of beetles and many other wood-boring species. Borates are highly toxic to fungal decay and many insects but are not harmful to humans or other mammals. This package is included on all windload doors.
