Frequently Asked Questions
What are the actual finished dimensions of CLS 75x50mm timber?
CLS 75x50mm timber is actually planed down to approximately 63x38mm finished size. The 75x50mm refers to the nominal sawn size before planing, which is standard practice in the timber industry.
Is CLS 75x50mm suitable for load-bearing walls?
CLS 75x50mm (finished 63x38mm) is primarily designed for non-load bearing internal partitions and stud walls. For load-bearing applications, you should consult a structural engineer and may need larger dimensions or higher grade timber.
How many CLS 75x50mm studs do I need per metre of wall?
For standard stud walls, place CLS studs at 400mm or 600mm centres. At 400mm centres, you'll need approximately 3 studs per metre, while 600mm centres requires about 2 studs per metre, plus additional studs for door openings.
Can I use CLS 75x50mm timber outdoors?
CLS timber is kiln-dried softwood designed for internal use only. It's not treated for outdoor exposure and will deteriorate quickly if used externally. For outdoor projects, use pressure-treated timber instead.
What's the difference between CLS and PSE timber?
CLS (Canadian Lumber Standard) has eased rounded corners for comfortable handling, while PSE (Planed Square Edge) has sharp square corners. CLS is specifically designed for construction work, making it easier to handle during framing projects.
