Whitewood Timber
4×1 whitewood, 100 by 22 mm, is the noggin and backing board of a timber frame: dwangs between studs, fixing grounds behind plasterboard, soffit and fascia backing, shuttering for small pours. Strength-graded to C24 and kiln-dried below 22% moisture content, it is certified stock rather than general-purpose board. It comes in 4.8 m lengths. Stocked in our warehouse for delivery across Ireland.
Why Whitewood?
Where this size earns its place is in holding a fixing. Plasterboard edges, kitchen rails, grab handles and wall brackets all need something solid behind them, and a graded 100 mm board gives you a predictable substrate instead of hoping a stud lands where you need it. It is pale and close-grained, so it takes screws without splitting and does not bleed resin through paint the way a knotty board can.
Installation guidance
Set noggins in a line rather than staggered where they will be used as a fixing ground, so whoever follows you can find them. Skew-nail or use framing anchors at each end; face-fixing through the stud is stronger but needs the stud reachable from both sides. Where the board is a plasterboard ground, keep the face flush with the stud line, because a proud noggin telegraphs through the finished wall.
Finishing & maintenance
Whitewood at this section is designed to be covered. It takes primer and paint well once the surface is clean and dry, but it has no built-in resistance to rot, so any external or damp-zone use calls for the treated equivalent from our C24 treated timber range. Store it flat and indoors if it will sit for more than a few days before it goes in. Compare it with the rest of our C24 timber range, from 22 mm boards up to 75 mm beams.
