Treated Carcassing Timber: choosing well

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.

Delivering carcassing timber in Witney

Timber is delivered in packs or bundles on a flatbed; long lengths need clear access along the drop point. Witney is inside our standard mainland delivery area.

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Give us the full postcode for the drop point; deliveries around OX28 are priced to the exact address.

Estimating your carcassing timber

A floor 4.8 m wide with joists spanning 3.6 m at 400 mm centres needs 13 joists, plus trimmers and noggins. The section and grade, such as 47 × 200 mm C24, come from span tables or your engineer; send us the timber schedule and we will price it.

Treated Carcassing Timber in Witney: questions

Can you deliver carcassing timber to a site with restricted access in Witney?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

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.

Is there a minimum order for delivery to Witney?

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.

Why is my treated timber green or brown?

The colour comes from the preservative. It fades over time and does not tell you how well the timber is protected; the use class does.
