The Reliability of TruExterior Siding

The Craftsman Collection™

Get the charm with full-thickness profiles and bold, defined shapes. It’s the ideal solution for homeowners who desire the look, feel and character of authentic wood siding while avoiding rotting, cracking, splitting and termite attacks.

Innovative Poly-Ash Technology

TruExterior products are made with fly-ash, a by-product recovered from coal combustion. When fly-ash is combined with polymers, it becomes a durable material that’s ideally suited for exterior siding and trim.

No Movement Issues

With a high level of dimensional stability, no special precautions or adhesives are needed to control or limit movement. There’s no need for special paints or limitations on paint colors, and installation is exactly the same, regardless of season.


Features and Benefits

  • Install using proven woodworking tools and methods
  • Accepts a wide variety of high-quality exterior grade fasteners suitable for the local environment
  • No need for pre-drilling, gluing, gapping and other cumbersome and costly intallation techniques.
  • Products come pre-primed and do not require paint
  • Not prone to movement caused by heat gain from dark colors
