Delivering carcassing timber in High Wycombe

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

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• On busy streets in High Wycombe, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

Sizing your order

A floor 3.6 m wide with joists spanning 3 m at 400 mm centres needs 10 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.

Things to check before you order

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.

C16 or C24?

C24 is stronger and stiffer, so it can span further or use a smaller section. Span tables and your structural drawings decide which grade and size you need.

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.

Treated Carcassing Timber questions

Do you deliver carcassing timber to trades and homeowners in High Wycombe?

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

Can I add other materials to my High Wycombe 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.

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.

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.
