Picking the right product

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.

Estimating your carcassing timber

A floor 6 m wide with joists spanning 3.9 m at 400 mm centres needs 16 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.

Before your Purley delivery arrives

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Common questions from Purley

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.

Can I add other materials to my Purley delivery?

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.

Do you deliver carcassing timber to trades and homeowners in Purley?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

What does C16 and C24 mean?

They are strength classes under BS EN 338. C24 timber is stronger and stiffer than C16, which lets it span further for the same size.
