TruExterior Poly-Ash Trim Boards & Siding - Available at Kuiken Brothers in NJ & NY

Kuiken Brothers is pleased to announce that we have added a new exterior trim board line to our stock offering. It is called TruExterior Trim. Unlike wood, it won’t rot, crack, or split. It’s so stable that it is even approved for ground contact meaning you could bury it and still nothing will happen to it. It has virtually no expansion and contraction and does not require end-sealing (the biggest cause of product failure with primed pine). It is also a reversible product and can be painted any color.

TruExterior Trim is made from a combination of a bio-based polymer and fly-ash (which is a byproduct of coal combustion). Combining the ash with a polymer makes a sustainable product with some excellent characteristics.

  • 1x4x16′
  • 1x6x16′
