SillBor®Borate Treatment

SillBor® borate preservative makes wood resistant to insect attack and fungal decay. It is suitable for interior, weather-shielded applications in areas that may be subject to sources of moisture but are not subject to direct contact with water.

Offering a host of environmental benefits, SillBor® wood is listed in the GreenSpec® directory of environmentally preferable products.

The Treated Wood Council’s Life Cycle Assessment (LCA) compares borate-treated framing with galvanized steel framing and found that borate-treated wood requires less energy and resources to produce, and it has a lower environmental impact for similar performance.
