ProWood Sill Plate treated lumber stacked at jobsite

ProWood Sill Plate

The greenest protection money can buy.

Sill Plate is a tough, versatile pressure-treated lumber. Like borate-treated lumber, it’s guaranteed to stop termites and prevent decay, plus it’s compatible with carbon steel (black iron) fasteners. But unlike borate-treated lumber, it requires no special handling.

Our sill plate lumber is both reliable and easy to work with, combining the advantage of several green certifications with the power to stand up to decades of pests and the elements.

ProWood® Sill plate's (MCA - Micronized Copper Azole) treated lumber is approved for any above-ground exterior application. Whenever the situation calls for superior quality pressure-treated lumber, consider the product that can handle it all.
