Barwon Timber’s range of LOSP primed pine is treated using an organic H3 Light Organic Solvent Preservative (LOSP) to resist termites.

LOSP Timber is most commonly used for above ground construction projects, including:

  • Weatherboards
  • Pergolas
  • Fascia
  • Window joinery
  • Framing
  • Decking

H3 LOSP timber’s active ingredient prevents decay and insect attack and can result in the treated wood having a residual smell, which will dissipate relatively quickly if stored in a dry well-ventilated environment.

This premium pine is manufactured by finger jointing and laminate, and pre-primed for an almost perfect finish.

Barwon Timber offers LOSP primed pine in a range of sizes. It is also supplied in grooved fascia.

FAQs

What is LOSP timber treated with?

LOSP is a type of treatment that contains white spirit and Copper Naphthenates with other chemicals to protect against insects or decay.

Do I need personal protection equipment when working with LOSP primed timber?

LOSP contains a preservative that is safe for use around people including children, and pets. However, handling, sawing, sanding any timber materials can present some hazards when airborne particles are generated in the process of working with these items.

See the EPA Working with and handling treated timber safely website for more information.

How to dispose of LOSP primed offcuts?

As with all treated timbers, do not burn offcuts or sawdust. Preservative-treated wood should be disposed of by approved local authority methods to prevent the spread of chemical pollutants leaching into the environment.

Can LOSP primed timber be used for internal building applications?

H3 LOSP primed timber is rated for outdoor above ground use in well ventilated areas.
