CONTROLS: . . Decay Fungi
IMPEL Rods are safe, low-cost, and EPA-approved as a decay protection and prevention system for wood. At recommended levels, IMPEL Rods will control existing decay and prevent future growth. IMPEL Rods are molded from fused, water-diffusible borates, which are highly effective and well established wood preservatives. They have an appearance similar to glass rods and are available in a variety of sizes for a wide range of applications.
IMPEL Rods are placed into holes drilled in wood at specifically determined locations and depend on moisture to activate the borates. IMPEL Rods are positioned in such a way that moisture will distribute the desired loadings of preservative throughout the target area.
For the eradication of existing decay and to preserve wood in high-risk areas, 6 oz. of Boric Acid Equivalent (BAE) per cubic foot of wood is recommended. As the moisture content inside wood rises to 25%-30% (the same levels where decay begins to thrive), IMPEL Rods begin to diffuse.
IMPEL's strong preservative is distributed throughout both heartwood and sapwood by moisture as it naturally moves through the wood. The IMPEL Rod system offers a long-lasting, highly concentrated, solid form of borate that slowly dissolves over time. The less consistently moist the environment, the longer IMPEL Rods will last.

When moisture levels rise, IMPEL Rods will dissolve and diffuse. |

Over time, the IMPEL Rod will continue to diffuse and provide protection. |
IMPEL Rods are available from PRGin the following sizes and quantities.
