Treated C24

C24 treated timber is kiln dried, planed and chemically treated. All edges are eased. C24 is a grading level which architects, engineers and builders often require. The C24 grade confirms the timber is of a certain strength. C24 timber is ideal for structural use as well as home DIY.

All our treated timber is impregnated with Lonza Tanalith solution. Tanalith gives the timber the ultimate long term protection against wood decay and insect attack, wherever the timber is to be used. Treated timber is ideal for outside use.
