Description

Timber cladding species suitable for many internal and external joinery applications.


Features and benefits:

  • It has excellent machining properties and can be planed to a smooth, clean finish. It can be glued, stained, varnished and painted satisfactorily, and takes nails and screws well.
  • Imported from Scandinavia.
  • For its weight, the timber is strong and moderately hard, Redwood machines well, allowing a nice smooth finish.
  • NORclad Brunnea, or NORclad Lite treatments offer a 30 year warranty when installed out of ground contact.
