Thermally treated wood cladding: performance, durability and natural aesthetics with Ecothermo technology

For your exterior wood cladding or interior wall covering projects, the Alti range by Sivalbp relies on the excellence of thermo-treated wood. Thanks to Ecothermo technology, a 100% natural process that uses no chemicals, the wood is permanently reinforced to offer increased resistance to weather, UV rays, humidity and insects, while retaining its natural beauty.

Environmentally friendly wood heat treatment technology

The Ecothermo process consists of heating the wood in several stages, interspersed with rehumidification phases. This thermal treatment improves the dimensional stability of the wood, makes it more resistant to climatic variations, and considerably extends its lifespan, without the addition of any chemicals or petroleum derivatives.

The advantages of Ecothermo thermo-treated wood cladding

  • Eco-friendly and sustainable wood cladding: chemically untreated, the wood retains its authenticity while meeting the requirements of sustainable construction.
  • Optimal performance in extreme conditions: perfectly suited to demanding environments (mountains, seaside, extreme temperature variations).
  • A natural and warm aesthetic finish: even, burnished colours inspired by nature, which age elegantly over time.

Thermo-treated wood species selected for their performance

The Alti by Sivalbp range offers several thermo-treated wood species, each with its own advantages:

  • Thermo-treated Larch (Alti-Cimes): a noble, durable and naturally resistant wood for high-end cladding.
  • Thermo-treated Northic Pine (Alti-Montagnes): excellent stability for projects in all regions.
  • Thermo-treated Alpine Spruce (Alti-Alpes): the raw, authentic charm of Alpine wood for unique façades.
  • Thermo-treated Nordic Spruce (Alti-Charvin): a soft, contemporary Scandinavian aesthetic, ideal for modern wooden houses.
