Why choose thermo-treated larch for your wood cladding?
A durable and elegant wood for cladding with character
Larch, or Larix, is a wood species known for its robustness and natural beauty, mainly sourced from the forests of the Alpine region. Appreciated for its distinctive grain and warm shades ranging from pink to golden brown, it gives wood cladding a warm, authentic look. To meet increased demands for durability and stability, Larch is also available in a thermally treated version: Thermo Larch is treated without chemicals, which enhances its natural qualities, improves its weather resistance and limits dimensional variations. This adaptation combines tradition and performance for durable and attractive wood cladding.
Larch: a dense and robust wood
Thanks to its high density, Larch is a hard and resilient wood, which reduces the risk of deformation and ensures excellent durability over time. At Sivalbp, we also offer Larch in a thermostabilised version, an innovative treatment that further improves its dimensional stability. This process makes Larch wood cladding even more resistant to changes in humidity and temperature, ideal for outdoor constructions and projects requiring increased longevity.
Thermostabilised larch: optimised performance
Thanks to advanced heat treatment, thermostabilised Larch offers exceptional resistance to weathering and climatic variations. This process enhances its durability and stability, making this wood an ideal choice for demanding outdoor applications. At Sivalbp, we promote this innovation to guarantee cladding solutions that are both attractive and high-performance, suitable for even the most ambitious projects.
Larch: a natural and authentic look
With its fine, light grain ranging from light blonde to reddish, Larch brings an elegant and warm touch to façades. Its natural patina improves with age, giving exterior façades a unique character.

FAQ : Everything you need to know about thermo-treated larch
What is thermo-treated larch?
Thermo larch is larch wood that has undergone natural heat treatment. This chemical-free process improves the wood's dimensional stability, insect resistance, and outdoor durability.
Why choose thermo-treated larch cladding?
Thermo-treated larch cladding combines the warm aesthetic appeal of larch with the performance of stabilized wood. It is more resistant to climatic variations, requires less maintenance, and offers increased durability.
What is the difference between natural larch and thermo-treated larch?
Natural larch is robust but can warp when exposed to moisture. Thermo larch, on the other hand, is heated to a high temperature, which reduces its water absorption rate, limits cracking, and extends its lifespan.
Is thermo-treated larch cladding environmentally friendly?
Yes. Heat treatment does not require any chemicals, only heat and steam. Thermally modified larch is therefore a healthy, natural, and recyclable material.
