ThermaCore

ThermaCore is our collection of thermally modified wood products engineered to deliver natural beauty with enhanced stability and durability. Through a specialized process using heat and steam, the wood is modified throughout, reducing its tendency to absorb moisture and improving dimensional stability for demanding exterior applications. Available in Ash, Southern Yellow Pine, Hemlock, and Spruce, ThermaCore offers distinctive grain, rich natural tones, and lasting performance. Our siding is available in a variety of profiles, textures, and factory-applied finishes, while ThermaCore decking provides a durable, natural wood surface for outdoor living spaces. Whether used as exterior cladding, soffit, or decking, ThermaCore combines the warmth and character of real wood with performance designed for the elements.
