• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

Getting the right carcassing timber

Which treatment?

Treatment is specified by use class. Timber inside a building is usually use class 1 or 2; external timber out of ground contact is use class 3; timber in ground contact needs use class 4.

Cut ends

Treat any cut ends with a suitable end-grain preservative, especially on external work.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Your questions answered

What sizes of joist do I need?

That depends on the span, spacing, loading and grade. Use span tables or your engineer's design; building control will check.

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

Yes. Put everything on one list, from carcassing timber to fixings and PPE, and we will price it as one delivery where the products can travel together.
