C24 timber is stronger and denser and used for more demanding projects where there is a need for higher load bearing. C24 Timber can be used for both domestic and commercial projects
C24 softwood timber tends to be grown slower to increase denseness. Boasting an average density of 420 kg/m5, it also contains fewer defects like knots and fissures.
