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.
Quantities: a worked example
A 3.6 m partition 2.4 m high at 400 mm centres takes 10 CLS studs, 7.2 m of head and sole plate and a row of noggins, then boarding on both sides. Work out the boards too
