Boral USA’s TruExterior Trim is a wood substitute for nonstructural, exterior applications such as fascia boards and window surrounds. Comprising bio-based polymers and flyash, the material resists rotting, splitting, freeze-thaw cycles, and termites without priming or end sealing. The trim comes in 16' lengths in nominal dimensions from 1x4 to 1x12, and 5/4x4 to 5/4x12. Made from at least 70% recycled or rapidly renewable materials, TruExterior Trim is Cradle-to-Cradle Certified Silver.
