Before your Ayrshire delivery arrives
CLS travels in bundles alongside plasterboard and is easy to hand off at the kerb. Our standard mainland delivery area covers Ayrshire.
- Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
Choosing CLS timber
Stud spacing
Studs are usually set at 400 mm or 600 mm centres to suit 1200 mm wide plasterboard.
Loadbearing walls
If the wall carries load it needs graded timber to a design. Plain CLS is not automatically structural.
CLS Studwork Timber questions
What is the difference between CLS and planed timber?
CLS has rounded edges and is sized for studwork; planed all round timber has square edges and comes in many more sizes for joinery and trim.
Can I add other materials to my Ayrshire delivery?
Yes. Put everything on one list, from CLS timber to fixings and PPE, and we will price it as one delivery where the products can travel together.
Do you deliver CLS timber to trades and homeowners in Ayrshire?
Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
How many studs do I need?
Divide the wall length by the stud spacing (400 or 600 mm), add one, then add plates and noggins. Our plasterboard calculator gives the boards for the same wall.
