White Oak wood is a very strong hardwood that is used for hardwood flooring, furniture, and exterior siding. Though often confused with Red Oak based on its appearance, White Oak lumber is actually harder, denser and much better than Red Oak when used for exterior applications. The pores are filled with a crystalline substance called Tyloses that acts like the caulk around your bath tub and makes the wood highly water resistant. We like it so much as an exterior product that we feature White Oak heavily in our Alpha line of cladding and decking

White Oak in our Alpha Cladding Line

White Oak in addition to being a great exterior wood, it takes color really well. Plus the stereotypical wood grain look you can get even under relatively solid finishes makes it a perfect option when only real wood will do. We have used it to create a wide variety of looks in our cladding lines.
