What is autoclave treatment of wood ?

Autoclave treatment is an essential solution to protect wood from fire risks. Wood is a material prized for its aesthetics and durability. However, in the face of the risk of fire, it becomes essential to apply a flame retardant treatment to your material to make it safer and compliant with regulations.

The autoclave treatment is an effective technique for giving wood fire-resistant properties, enabling it to meet high safety standards, such as the French M1 standard or Euroclass up to level B-s1,d0. This method is ideal for projects requiring enhanced fire protection, while preserving the natural appearance and qualities of the wood.

During an autoclave treatment, the wood is placed in an airtight tank, into which the fire retardant product is injected. Pressurization ensures the penetration of the fire retardant to the core of the wood.

Why autoclave treatment on wood ?

Autoclave treatment is essential to reduce the natural combustibility of wood and thus minimize the risks in the event of a fire. There are many reasons to adopt this solution :

Increased safety : Autoclave treatment considerably delays the spread of fire. This treatment allows the wood to obtain the French standard M1 or up to Euroclass B-s1,d0, which corresponds to a classification of “non-flammable” materials. In the event of a fire, this type of wood limits the speed of flame propagation and reduces the emission of toxic fumes.
Regulatory obligations : In certain public or private buildings, such as establishments open to the public, construction projects must meet strict fire resistance standards. Autoclave treatment is a solution that makes it possible to comply with these legal and regulatory requirements.
Durability and aesthetics : Unlike other types of treatments, autoclave fireproofing does not alter the appearance of the wood. This retains its texture and natural color while making it safer. In addition, this process does not affect the wood’s durability against other agents of degradation, such as insects or humidity. By penetrating the treatment to the heart of the wood, it is protected against surface wear.

Opting for autoclave treatment guarantees safety and preserves the aesthetics of the wood for projects requiring a material that is both beautiful and fire-resistant.

Carrying out the autoclave treatment on wood

This fire-retardant treatment follows a rigorous process to guarantee optimal fire protection for the wood. Here are the main steps of this fireproofing method :

Selection and preparation of wood : Before being treated, the wood is selected and prepared according to its use. It is first dried to reduce its moisture content, allowing for better absorption of flame retardants.
Insertion into the autoclave : Once ready, the wood is placed in an airtight chamber called an autoclave. This installation is designed to impregnate the wood with fire retardants under high pressure, guaranteeing in-depth protection.
Creation of a vacuum : Inside the autoclave, a vacuum phase is implemented to eliminate the air and humidity contained in the wood fibers. This step is essential to prepare the wood to receive the fire retardants.
Injection of flame retardants under pressure : A specific flame retardant solution is then injected under high pressure. This process allows the products to penetrate deep into the wood fibers, ensuring long-lasting and effective protection against fire.
Drying and stabilization : After impregnation, the wood is dried to stabilize the fire retardants in its structure. The wood is then ready to be used, resisting fire while retaining its natural appearance.
