Engineered Wood Siding and Trim (EWST) offer a versatile range of textures, widths, and profiles for both interior and exterior applications. Crafted from inter-felted lignocellulosic fibers and consolidated under heat and pressure, these advanced composites replicate the look of traditional wood while offering superior performance.
Enhanced with moisture resistance, dimensional stability, and protection against fungal decay and termites, EWST delivers long-lasting durability. Available in a variety of finishes, including sophisticated woodgrains and embossed surfaces, these high-performance panels combine beauty with resilience. Additionally, EWST products may contribute to LEED credits, supporting sustainable building practices.

EWST Engineered to Excel
Engineered wood siding and trim is available in smooth and textured finishes with a range of widths and profiles, unlocking many design possibilities. Engineered for both interior and exterior applications, these versatile panels seamlessly combine durability, style, and creativity. Whether elevating a home’s exterior or adding depth to interior spaces, EWST delivers lasting beauty and performance.
Product Standards
The ANSI A135.6 for Engineered Wood Siding defines quality and dimensional attributes for siding products. The standard covers the requirements and methods of testing for exterior durability, dimensions, straightness, squareness, physical properties, and surface characteristics. It also includes trade terms and methods of identifying engineered wood siding. ANSI A135.7 Engineered Wood Trim covers the requirements and methods of testing for exterior durability, and physical and mechanical properties for trim products.
Third-party certification to these standards is often required by building codes, and the Composite Panel Association (CPA) offers a recognized Grademark Certification Program for compliance. Copies of the standards are available at Compositepanel.org.
