Whitewood Timber
4.5×1.5 whitewood, 115 by 35 mm, is the partition size to use when the wall has to carry services. The extra 15 mm over a 4×1.5 is what lets pipework and conduit pass through the frame without notching a stud to the point of weakening it. Strength-graded to C24 and kiln-dried below 22% moisture content. Lengths run from 4.2 m to 5.4 m. Stocked in our warehouse for delivery across Ireland.
Why Whitewood?
Most partition failures are not structural, they are service related: a plumber notches three studs in a row to get a waste across, and the wall goes soft. A deeper stud gives you room to drill rather than notch, and a drilled hole on the centre line takes far less out of a stud than a notch in its edge. That single change is usually worth the small extra cost of the section.
Installation guidance
Drill service holes on the centre line of the stud width, keep them to no more than a quarter of the depth, and space them at least three diameters apart. Keep holes away from the top and bottom quarter of the stud height where the frame is working hardest. Where a large waste pipe has to cross, frame an opening with doubled studs and a header rather than cutting the run.
Finishing & maintenance
Whitewood at this section is built to be covered and kept dry. A service wall is also the wall most likely to see a leak, so in a bathroom, utility or plant room specify the treated equivalent from our C24 treated timber range and seal around any pipe penetration properly. Store flat and indoors before use. For the other partition sizes, see our full C24 timber range. To compare sawn and treated sizes side by side, see our construction timber page.
