Coos Head offers Borate treated wood for special climate and use conditions where the end use application is above ground and fully protected from the weather. Our Advance Guard® Borate pressure treated wood products have long-term protection that is a step up in quality construction. Above ground Borate treated wood works in sill plate on foundations or as sub flooring in utility rooms and bathrooms. It can also be used for interior framing as well as floor and roof sheathing.

Builders can depend on Advance Guard® products to provide–long lasting, built-in protection against termites, including Formosan termites, fungal decay and many other wood damaging organisms.
