Thermowood cladding for facades, saunas and interiors

Thermoarena thermowood cladding is made from thermally modified pine and ayous. Heat treatment at 180–220 °C without chemicals gives the boards excellent dimensional stability, low water absorption and resistance to decay – thermo pine and thermo ayous both reach EN 350 durability class 1–2. That makes them ideal for facades, terrace and sauna walls, ceilings and interiors.

Profiles

  • UTS and UTV – 20 mm tongue-and-groove cladding; UTV has a V-groove.
  • UYS and UYV – 20 mm tongue-and-groove cladding; UYV has a V-edge.
  • VCLIP – clip cladding fixed with plastic clips to special rails; horizontal, vertical, diagonal or even on ceilings, with no visible screws.
  • HSS 42×28 and 42×42 – slanted lath for open slatted facades.

Species and sizes

Thermo pine is live-knotty Scandinavian pine in 20×92, 20×117 and 20×140 mm, lengths 1.8–5.1 m. Thermo ayous is a light African hardwood, knot-free on 3–4 sides and a good alternative to Western Red Cedar; it comes in 20×92 and 20×140 mm (VCLIP also 20×190 mm), lengths 2.1–4.5 m. Coverage for UTV: 20×92 ≈ 12.2 running metres per m², 20×117 ≈ 9.35 and 20×140 ≈ 7.69.

Finishes and installation

Boards are available untreated, pre-oiled with UV protection, painted in colours, fire-retardant impregnated or brushed. Untreated thermowood turns silver-grey outdoors; a pigmented oil or factory finish keeps the colour longer. Install vertically or horizontally over a ventilated cavity using stainless screws or nails, and pre-drill near board ends, as thermowood is slightly more brittle than ordinary timber.

Questions & answers

What is the difference between UTS, UTV, UYS and UYV?
All four are 20 mm tongue-and-groove cladding profiles in two families, UT and UY. The V versions have a V-groove (UTV) or a V-edge (UYV) that creates a distinct shadow line between boards.
Thermo pine or thermo ayous – which should I choose?
Thermo pine is live-knotty Scandinavian pine in lengths 1.8–5.1 m. Thermo ayous is a light African hardwood, knot-free on 3–4 sides, 2.1–4.5 m long and an alternative to Western Red Cedar; both are EN 350 class 1–2.
What is VCLIP clip cladding?
VCLIP boards are fixed with plastic clips to special rails, so no screws are visible. It can be installed horizontally, vertically, diagonally and on ceilings, in pine 20×117/140 mm and ayous 20×92/140/190 mm.
Which finishes are available, and will the cladding turn grey?
Choose pre-oiled with UV protection, painted, fire-retardant impregnated or brushed boards. Untreated thermowood weathers to silver-grey outdoors; a pigmented oil or factory finish keeps the brown colour longer.
