reSAWN TIMBER co. is proud to introduce Sylva™ thermally modified wood cladding. Sylva features wood cladding that is sourced from abundant and sustainably grown U.S. forests. Currently, our offering consists of Thermally Modified North American Red Oak products that are locally sourced and manufactured in Pennsylvania. They are stable, weather-resistant, FSC®-Certified, and comply with Wildland Urban Interface (WUI) requirements, ensuring their longevity.

North American Red Oak is the most abundant hardwood in the eastern and central regions of the United States and southern Canada. The species thrives in cold, wet winters and hot, humid summers, making it extremely adaptable to various climates. Red Oaks are fast-growing, sprouting up to 24 inches per year and reaching a mature height of 60 to 90 feet. They flourish in sunlight and require a gap in the canopy to mature. Red Oak features a uniform heartwood color and tight growth rings. 

Thermally modified wood is made by heating hardwood up to 400 degrees Fahrenheit and followed by a steaming process to recondition the wood. The modification changes the wood’s molecular structure, making it highly durable and resistant to water damage.
