Frequently Asked Questions
Start with the use category and end environment. MicroPro® and NatureWood® are engineered for exterior above-ground and ground-contact applications, while Advance Guard® and Hi-Bor® protect interior framing against termites and decay. Tell us about your project and our technical team will recommend the right treatment.
Micronized copper systems like MicroPro® disperse fine copper particles into the wood for durable exterior protection in wet, above-ground, and ground-contact conditions. Borate systems like Advance Guard® and Hi-Bor® are formulated for dry interior framing, defending against wood-destroying insects and fungal decay.
Yes. Our preservatives are EPA-registered, and several carry third-party environmental certifications such as SCS Environmentally Preferable Product and NGBS Green Certification. Long-lived treated wood also keeps carbon stored for decades, supporting our broader sustainability commitment.
Our preservative systems are evaluated against recognized standards including ICC-ES acceptance criteria and the relevant AWPA use-category standards (for example AWPA T1 and P50). Each product page lists the specific certifications and standards that apply to that treatment.
