22mm nominal loglap — our thickest timber board, only on Heavy Duty.
When someone wants their building to feel properly solid, loglap is what we reach for. At 22mm nominal it's a genuinely thicker board than standard shiplap, with a rounded profile that reads as chunky and substantial — and because there's more timber to protect, it carries our longest anti-rot warranty. It's the one change that defines the Heavy Duty range.
Dimensions
22mm nominal (19mm finished) Tanalised tongue-and-groove loglap board
Loglap shown in cross-section — 22mm nominal, 19mm finished, rounded profile.
Nominal is the sawn size before the board is planed; finished is the actual thickness you receive, once it’s planed smooth and machined with its tongue-and-groove edge. Every timber mill works this way — we publish both so you know exactly what you’re getting.
Heavy Duty steps the cladding up from 16mm to 22mm nominal loglap (19mm once it's planed to its finished thickness) — genuinely thicker timber, with a rounded tongue-and-groove profile rather than shiplap's flat overlap. It's the only difference between standard and Heavy Duty: same frame, same floor, same roof — just a thicker, longer-warrantied board wrapped around it.
