Total Sheds
No spin — just the published specs
The same canon of verified numbers our product pages run on, side by side — including the nominal-and-finished sizes most manufacturers won't print.
Cladding is the building. Thicker boards move less, seal better and shrug off knocks — and the tongue-and-groove profile is what keeps wind-driven rain out of the joints.
The skeleton every panel hangs off. 38×50mm pressure-treated framing is the same on all three builds — we don’t thin the frame to hit a price.
Felt is the industry standard and fine for years; one continuous EPDM rubber membrane has no seams to lift and carries a 20-year anti-leak warranty (30 fitted by us).
The invisible layer most cheap sheds skip to save £10–£30 — it lets moisture out of the walls while keeping wind-driven rain off the frame.
Tanalith E vacuum pressure treatment forces preservative deep into the timber cells (UC3-rated) — dip-treated sheds only coat the surface. Composite needs none at all.
Timber wants an optional colour refresh every 2–3 years to stay looking sharp. Composite is colour-through — nothing to treat, ever.
The number that tells you what the maker really thinks of the build: 15 years anti-rot as standard, 20 on Heavy Duty, 30 on composite.
Timber is measured before machining — that "sawn" size is the nominal figure. Planing it smooth and cutting the tongue-and-groove profile removes a few millimetres, so a 16mm nominal board finishes at around 12mm, and a 24mm nominal floor board finishes at around 18mm.
Every timber manufacturer works this way — but most only quote the bigger nominal number. We publish both, so you can compare buildings on the wood you actually get, not the wood it started as.
Prices depend on size — every size page shows all three builds priced live, and Heavy Duty re-prices instantly in the Build studio.
