Cladding
A facade that keeps its lines.
Half the seasonal movement of untreated wood means joints stay tight and shadow lines stay straight — the two things a wood facade is judged on.
Profiles
Six profiles, drawn in section.
These are the actual milled sections. Pick a profile for pricing, coverage, and species options — or send your own drawing and we grind the knives.

More options
Three ways to build a wall.
TG profiles
TG-STriple, TG-Triple, TG-Lap, and TG-I/U/V/W in 3/4" and 1" pine, plus radiata and ayous. Three shadow lines per board on the triples, blind-nailed, weather-tight.
IN STOCK 02 Battens & screensDimensional stock
1x4 and 2x4 thermowood for battens, screens, slat walls, and soffit runs — the same Thermo-D pine, straight and stable.
MILLED TO ORDER 03 Open joint & rainscreenYour profile
Send your own section drawing — shiplap reveals, open-joint rainscreens, matched historical profiles. We grind the knives for a flat tooling charge and keep them on file.
Weathering
Honey now, silver later.
The roast color runs through the full thickness of the board — it's the result of the 212 °C treatment, not a stain. Cut it, sand it, rout it: the color is still there.
Left uncoated, the honey-brown face weathers to an even silver-grey patina over the first year or two. That's expected weathering, not a defect — and many architects spec it on purpose.
Want to keep the roast tone? A UV-protective oil every few years holds the color. Either way, the rot resistance never depends on the finish.
Installation
Standard carpentry, three rules.
Any carpenter who has hung wood siding can hang thermowood. Ventilate behind the boards, use stainless fasteners, and seal cut ends. That's the whole list.
Every bundle ships with an installation sheet, and if your crew hits something unusual on site, the people who milled the boards answer the phone.
