Working out quantities for your Islington job

A floor 4.2 m wide with joists spanning 3.3 m at 400 mm centres needs 12 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.

Delivery to Islington: what helps

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

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• If neighbours share the access, it helps to let them know a lorry is coming.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

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.

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.

Your questions answered

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

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 Islington?

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.
