Thermally Modified Wood Trim by Edge is the perfect complement to Edge's Thermally Modified Wood cladding boards. Not only will this trim create lasting curb appeal, it's also more durable than typical wood trim because it resists rot. The innovative thermal modification process stabilizes the wood, making it less vulnerable to shrinking and seasonal expansion and contraction. Our thermally modified boards come in a variety of on-trend prestained and natural colors. These square edge trim boards can be installed on both interior and exterior siding, wall, and ceiling applications. Our finishing process highlights the natural and random variation of the wood grain. These variations help provide a unique finish for each board.
