Before you order 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.

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.

How delivery works in Isleworth

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

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If neighbours share the access, it helps to let them know a lorry is coming.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Sizing your order

A floor 3 m wide with joists spanning 3.6 m at 400 mm centres needs 9 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.

Ordering carcassing timber for Isleworth: FAQs

How soon can carcassing timber be delivered in Isleworth?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

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.

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.

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

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