Sill Plate
This Blue Does More.
In the past, blue-tinted borates were the builder’s economical choice for sill plate. But saving a few bucks comes at a cost – borate-treated lumber requires special handling, since it leaches its protective chemical if left in the elements. The simple solution is ProWood® Sill Plate, made with Micro CA.
ProWood Sill Plate has all the advantages of borates:
- Lifetime protection against termites and decay
- Compatibility with carbon steel (black iron) fasteners
With the added benefits of:
- Several green certifications
- Approvals for any above ground exterior application
All this while being priced competitively with borates.

Its process has won green certifications including the GREENGUARD Children & Schools Certification, Environmentally Preferable Product (EPP) status, and NAHB Green Product Award. ProWood Sill Plate is also building
