Made by Earth

Sioo:x patented wood protection has been inspired and designed by nature.

Featured: Twin Gables

Nestled among the orchards and wineries, the Twin Gable residence on Long Island, NY, combines deliberate modern design functionality with classic farmhouse forms that are familiar to the local vernacular. Vertical panels of Vulcan Radiata Pine dress the exterior of the home in a subdued, neutral wood-tone with exceptional texture. With over 8000 square feet of SiOO:X-treated Vulcan-timber, Twin Gables exemplifies the versatility of the product.
