Interior Framing, Decay, and Termite Protection

Termite attack on wooden structures in the United States leads to billions of dollars in damages each year. Formosan termite activity in Hawaii and the southern US has been well documented, and has led to a significant increase in the frequency and severity of termite damage caused to homes and commercial structures.

Wood frame construction made with borate pressure treated wood is protected against damage from both decay and Formosan termites.

  • Non-corrosive to metal fasteners
  • Does not adversely affect the
    strength properties of the treated
    lumber or plywood
  • Backed by a 20-year limited warranty against Formosan and other termite species, and fungal decay in dry interior applications

Our borate-protected wood is backed with a 20-year limited warranty.

Our borate pressure streated  lumber and plywood is pressure-treated with a borate-based wood preservative (Disodium Octoborate Tetrahydrate – DOT) that protects against Formosan and other termite species, and fungal decay in dry interior applications.

Nails, Fasteners, and Connectors

Corrosion test data shows that borate treated wood has connector corrosion rates similar or equal to untreated wood; however, building codes require the use of corrosion-resistant connectors in contact with all treated wood. Contact connector manufacturers for up-to-date recommendations on specific connectors for use with your treated wood product.

Safe Practices

  • Wear gloves when working with wood.
  • Wear a dust mask when machining any wood to reduce the inhalation of wood dusts.
  • Wear appropriate eye protection to reduce the potential for eye injury from wood particles and flying debris during machining.
    Wash hands thoroughly with mild soap and water after working with treated wood.
  • All sawdust and debris should be cleaned up and disposed of after construction in accordance with local waste management regulations.
  • Do not burn pressure-treated wood.
  • Wash work clothes separately from other household clothing before reuse. Pressure-treated wood should not be used where it may come into direct or indirect contact with drinking water, except for uses involving incidental contact such as fresh water docks and bridges.
  • Do not use pressure-treated wood in circumstances where the preservative may become a component of food, animal feed or beehives.
  • Do not use pressure-treated wood for mulch.
  • Treated wood should be disposed of in landfills or burned in commercial or industrial incinerators orboilers in accordance with federal, state and local regulations.
