We are considering installing a kid playset with tree house and have seen one in a local warehouse club that we like.
The brochure for that playset states that it is dade almost entirely of Cedar, Cypress, or Redwood (Non - Pressure Treated).
With pine that is used for decking, my understanding is that the pine wood must be pressure treated for longevity.
Does Cedar, Cypress, Redwood also need to be pressure treated for longevity?
Thanks Bob
