The thermo-treatment process accelerates the aging of wood to make it similar to 350-year old lumber. The process eliminates all moisture, resins, sugars, organisms, and bacteria in the wood. In opposite to reclaimed lumber, which was staying outdoors for decades, our product is free of any insects and bacteria. Bringing reclaimed outdoor lumber to your home is not safe: you'll bring all chemicals and insects with this. The thermo-modified wood is pure and it is a 100% Green product. Our planks are perfectly milled, plus thermo-treatment adds dimension stability for the wood. The product is domestically made from American lumber. Our home decor wall planks are great for both residential and commercial applications such as accent walls, wainscoting, wall tiles, ceilings, wall art, headboards, underbars, upgrades for furniture and doors, and many others. Every piece is manually selected to combine our sets for the best look and performance. The planks have are wire brushed to eliminate splinters and create a 3D textured surface. Thermo-treatment makes wood essentially durable: you may use our planks in high humidity environments, such as bathrooms, kitchens, basements, pool areas and light backsplash areas. DIY installation kit included in each box (fasteners and one pre-cut starter/end plank). See installation instructions for details. Color: Varies from Light Brown to Dark Brown (almost Black).
