Common zinc borate OSB Questions
What is zinc borate treated OSB?
Zinc borate treated OSB is oriented strand board protected from termites, fungal decay, and moisture with zinc borate.
How are the panels treated?
The zinc borate is mixed into the strands before pressing, so it spreads throughout the board, not just on the surface.
When should I choose zinc borate OSB?
In many cases, zinc borate OSB can replace pressure treated plywood at a lower cost without reducing quality or performance. Zinc borate OSB should be considered when building in a climate prone to mold, fungal decay and termite damage.
