Technical Information

*TruGrain panels are not sold by Knight Wall Systems. See TruGrains website for more details and the latest technical information.


  • WATER RESISTANCE: Resysta does not absorb any water, therefore it can neither splinter, crack nor swell – it is exactly these properties that make it an extremely durable material.
  • WORKABLE LIKE WOOD: Resysta can be easily sanded, milled, drilled, sawed, stained and glued.
  • UV RESISTANT: Resysta is extremely resistant against UV radiation (ASTM G154) over many years and will never grey.
  • EASY INSTALLATION: Resysta panels are shipped in standard lengths and can easily be cut to size in the field for a precise and cost effective installation.
  • SUSTAINABILITY: Resysta mainly consists of rice husk – a by-product of rice production. Rice husk is a rapidly renewable resource.
  • 100% RECYCLABLE: Resysta can be pulverised and new Resysta products may be processed out of it.
