LOSP Timber – Superior Protection for Outdoor Projects

Greenhill Timbers' Light Organic Solvent Preservative (LOSP) treated timber offers the ultimate defence against Australia's challenging outdoor conditions. The advanced treatment process forces protective agents deep into the timber's cellular structure, creating long-lasting resistance to termites, fungal decay, and moisture damage without compromising workability.

Its ideal applications include:

• Exterior cladding and weatherboards – For weather-tight building envelopes
• Decks & pergolas – Where appearance and durability matter equally
• Window/door joinery – Stable timber that won't warp or twist
• Fascia and bargeboards – Critical elements requiring reliable protection

Key advantages of our LOSP treatment includes:

• Clear finish retention – Unlike CCA treatments, it accepts stains and paints effortlessly
• Low maintenance – It requires only occasional recoating after decades of service
• Full traceability – Every batch of the timber comes with treatment certification
• Custom profiling – It is available in multiple decorative finishes
