Before you order CLS timber
Stud spacing
Studs are usually set at 400 mm or 600 mm centres to suit 1200 mm wide plasterboard.
Which size?
38 × 63 mm suits most partitions up to standard ceiling heights. 38 × 89 mm gives stiffer, taller walls and more room for insulation.
Getting CLS timber onto your Perth site
CLS travels in bundles alongside plasterboard and is easy to hand off at the kerb. Perth is inside our standard mainland delivery area.
- Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
- In summer Perth gets around 17h 43m of daylight, but early deliveries still beat the traffic and give the longest working day.
- If neighbours share the access, it helps to let them know a lorry is coming.
