Charwood is a Japanese style of charred wood called Shou-Sugi-Ban, a process of finishing siding that dates back hundreds of years. Montana Timber Products has mastered our own proprietary finishing process to ensure the highest quality and character. There are a variety of styles available within the Charwood line to meet your range of design schemes – from light to heavy charring and multiple color tones. All Charwood products are stained and sealed for lasting protection, whether applied inside or out. Bring a modern style to your project with this ancient process of treating wood.
