Key Points

  • For most species of timber, the total coverage rate to work to is 3.7m²/L.  For cedar, only the total coverage rate is 2.7m²/L to achieve Euro Class B and Class 0 spread of flame and fire propagation.
  • For cladding, we recommend coating all sides of the panels.
  • We recommend the cladding being a minimum of 14mm.
  • With Zeroflame Treatment the timber should be unsealed to enable the Treatment to be absorbed.

Ruby UK - Timber

Please Note: All timber products are finished in metric and that softwood is a natural product that can twist and warp through changes of climate conditions. We advise customers not to install or apply any further treatment until the timber is fully dry, as this could cause the timber to split and warp. Timber sizes can also vary due to the weather conditions before dispatch. Please allow for up to 5mm variance. As all our timber is stored outdoors you may receive moist timber, this is perfectly normal. This will not affect the structural integrity of the timber.
