C16 vs C24 timber
Many customers ask about C16 vs C24 timber. The main difference is strength. C24 is stronger and often used for heavy loads or larger spans. However, C16 timber is more than enough for most internal structural work, offering great value without compromising safety.
Why choose C16 treated timber?
For outdoor or damp environments, choose C16 treated timber. It’s pressure-treated to resist rot, fungal decay, and insect attack. This makes it a smart choice for joists in ground-floor areas or outdoor frames where durability matters.
