The wait is over for the new Zinc Borate Treated OSB!

Extreme Panels is very excited to announce that in 2017 we have switched 100% production of our SIPs over to using Zinc Borate Treated OSB.  Our new SIPs are now protected against biological elements including fungal decay & ensure long-term durability against wood boring/eating insects!  We are calling this value-added upgrade to our SIPs “Structure Shield+”
