Borate Pressure-treated Lumber

Borate

Borate is the most cost-effective and environmentally friendly way to build lasting protection into your home. Distinguished by its bluish hue, this lumber is specially treated to resist the Formosan termite. The only sure protection against this termite is to "build with borates."

Borate is rot-resistant wood. It also protects against:

  • Standard termites
  • Carpenter ants
  • Roaches
  • Dry rot
  • Fungal decay
  • Wood-boring beetles

What Is Borate?

Borate has been treated with natural mineral salts called borates to protect against termites and other damage. Borates, which are made from the element boron, are toxic to insects, but safe for humans, pets, and the environment. Borate products have been in use for more than 100 years. In fact, you can find borates throughout your home, in many common materials and products.

Can Be Used for Sill Plates

Borate products are designed for interior use, but it can be used for sill plates, too. Borate will give added termite protection to your sill plates at a cost that’s less than other treated wood products. Borate treated lumber should not be used in unprotected exterior areas.

Costs a Bit More, But Worth It

Borate looks, smells, and handles like conventional wood. Building with borates does cost a bit more, but it’s worth it. The one-time added cost—typically 2% of the total construction cost—of building with borate-treated lumber is far less than the cost of repairing the damage termites typically cause. It’s also less than the cost of ongoing, short-term treatments for termites and wood rot. Plus, Borate is not corrosive to fasteners, so expensive fasteners aren’t required.

Most important, Borate is guaranteed as a termite barrier with a lifetime limited warranty longer than traditional termite-control methods.
