The role and potential of pressure treatment in the wood industry
It can be confidently stated that the use of wood in construction has been steadily increasing in recent times. This is primarily because wood is a natural, renewable, and sustainable material. However, wood is naturally flammable, making it necessary to apply effective methods and treatments to improve its fire resistance. In addition to the properties of fire retardants themselves, one of the most effective solutions is autoclave treatment, which provides deep impregnation and ensures high durability of wood materials in the event of a fire.
What is Autoclave Treatment, and Why is it Important?
Autoclave treatment is a high-pressure method used to impregnate wood with deep-penetrating chemicals, such as fire retardants. During this process, wood is placed in an autoclave — a specialized pressure chamber — where a combination of vacuum and high pressure forces the chemical deep into the wood’s structure. This ensures that the fire retardant doesn’t remain only on the surface layers of the wood but penetrates deeply into its structure. The result is a material that is uniformly and long-term protected, even during intensive use or further processing of the wood.
Traditional surface treatments, such as brushing or spraying, only coat the exterior of the wood. This leaves the interior unprotected, making the wood fire-prone if the surface is damaged or the material is cut. Autoclave treatment solves this issue by providing uniform protection throughout the wood mass.
Benefits of Autoclave Treatment
Long-lasting Protection – Deep impregnation ensures the effectiveness of fire retardants even after processing, cutting, or altering the wood’s thickness.
Improved Fire Resistance – The process achieves higher fire safety standards, such as the EN 13501-1 classification of B-s1, d0, offered by innovative solutions like SPFR100.
Cost-Effective and Durable – Deep impregnation enhances the wood’s resistance to both fire and weather conditions, providing significantly better protection than surface treatments.
Added Value and Modern Solutions
To improve fire safety, new ecological technologies are especially important as they are effective, environmentally friendly, and durable. Solid Protect’s SPFR100 is based on innovative polymerization technology, which ensures not only excellent fire safety but also weather resistance without compromising the wood’s natural aesthetic appearance. This is particularly important for both indoor and outdoor applications.
The combination of autoclave treatment and SPFR100 is an ideal solution, allowing the substance to deeply and evenly penetrate the wood structure. Unlike many traditional products that contain binders, SPFR100 is binder-free, preserving the natural properties of the wood while preventing degradation and the leaching of salts in weather conditions.
Wide Application Potential of Autoclave Treatment
Autoclave treatment, combined with high-quality fire retardants, is essential not only in residential construction but also in large-scale industrial projects where high safety standards are required. Additionally, it opens up opportunities to expand the use of wood in areas such as high-rise buildings, public facilities, and infrastructure projects, where traditional application methods and fire retardant properties may not meet the necessary fire safety requirements.
Autoclave treatment is becoming increasingly popular, and the construction industry is moving toward more sustainable and durable solutions, where autoclave treatment plays a key role in expanding the possibilities for using wood.
