Our LONGLAST range is recommended for any ground contact product. It is treated to the British Standard BS8417 and has a 15 year life expectancy. Only correctly prepared timber will reach our Longlast standard treated to usage class 4 (UC4). All of our Timber is treated with Wolmanit® CX
SPECIES: Only Redwoods are used for the Longlast range due to their natural durability.
DRYING: Timber is naturally air dried to 28% moisture content. The pressure treatment is then absorbed and retained through the sapwood to the durable heartwood.
PREPARATION: Layers of timber are separated by spacers which allow for consistent drying and treatment right through the pack.
The Longlast range is the correct choice to ensure a quality ground contact product. Choosing the right product reduces ta lifetime of costs. A small premium reduces the very real risk of premature failure and expensive re-installation costs.
All of our timber is assured as being from PEFC Controlled Sustainable Sources and sourced as locally as possible, mainly in the South West of England.
Remember! Treat any cut/drilled areas of the LONGLAST products as this will affect the performance of the product in invalidate the warranty.
