Outdoor Products

Wood has long been the choice of builders - being beautiful, versatile and easy to work with. However, wood is also subject to rot, fungal decay and insect attack.

Tenon has developed a range of outdoor boards and moulded products under the LIFESPAN® brand, that deliver all the benefits of wood, combined with long-lasting durability.

Tenon's outdoor products are protected with the combination of a pressure treatment using organic biocides to ward off insects and fungal decay; a proprietary water repellency system to maximize dimensional stability; and two coats of an alkyd-based primer to provide superior durability against the elements.

Our raw materials come only from renewable sources and we utilize leading technology and innovative techniques to maximize the recovery of logs into finished products and minimize waste in our mills.

Tenon outdoor products have a limited lifetime substrate warranty against fungal decay and insect damage, including termites. Other features include:

  • FSC® certified products available on request
  • Non-corrosive to fasteners
  • Organic Pressure Treatment approved in New Zealand, Australia, UK and USA
  • Multi-layer protection resists water uptake
  • Alkyd primer provides smooth defect-free surface
  • Suitable for both exterior (above ground) and interior use


In response to requests from customers seeking a higher quality, exterior wood product, Tenon in June 2012 introduced the additional LIFESPAN® SOLID SELECT (www.lifespansolidselect.com) range of trim boards, and siding.

Sourced from New Zealand's renowned radiata pine forests, LIFESPAN® SOLID SELECT is made from only the highest quality, long length clear boards, with no fingerjoints or knots.
