For architects & specifiers

Timber cladding, taught from the sawdust.

A RIBA-style CPD session on specifying timber cladding — species, profiles, fire, finishes and the mistakes we see in specs every week. At your practice over lunch, or here at the mill where you can watch the answer being made.

The session

One hour, six things worth knowing.

Built for practices that specify cladding a few times a year and want it right, not for timber anoraks. Bring the awkward questions.

  • Species & durability Seven timbers, durability classes, and where each one belongs — and doesn’t.
  • Profiles & fixing Shadowgap to secretfix: what each profile does, and the fixing mistakes that fail façades.
  • Fire treatment & regs Euroclass B, Nordtreat, and what the regulations actually require where.
  • Finishes & weathering Stains, opaque coatings, SIOO:X and charring — and honest weathering timelines for each.
  • Specification & NBS Writing H21 clauses that describe something a mill can actually make.
  • Cost drivers What moves the per-m² price — and where the budget goes furthest.

Two ways to run it

Your practice, or our mill.

At your practice

Lunchtime session at your office — we bring the boards, every species and finish, so the whole team handles the material while they eat. One hour, questions included.

At the mill

Pomathorn Farm, Penicuik — 15,000 sq ft of sawmilling, charring and coating. Watch boards machined and Shou Sugi Ban burnt, then handle everything in the showroom. The version people remember.
