The innovative use of an aluminium laminate in the Field Liner extends the service life of timber poles while in the ground, while two active packaging layers prevent the wood from being damaged by fungal growth and termites. The alufoil layer provides barrier protection to prevent harmful wood preservatives (e.g. creosote or CCA) from leaching out and contaminating the soil while an additional advantage is that the preservative penetrates further into the wood than would otherwise be possible.
