Wood treatments
By treating wood, we are simply contributing to the sustainability of forest resources. We know that untreated wood, when exposed to certain conditions, has a lifespan of less than two or three years, since nature contains a variety of agents and predators that lead to its destruction.
By treating wood using various processes, we are able to increase its lifespan up to 15 times and, as a result, significantly reduce its consumption.
Autoclave treatment
Autoclave treatment is a chemical process using vacuum and pressure. Toscca treats wood in accordance with standard EN 335-1, which guarantees long-lasting treatment of all sapwood, regardless of its size.
The safety and thoroughness of our treatment process ensure a 20-year guarantee against rot, even when the wood is exposed to the elements and in direct contact with the ground.
The latest technology allows us to treat with a green, brown or grey color. The chemical process and the fungicide agent used are always the same, and what changes the color of the wood at the end of the process is the pigment that is added to it.
Velature treatment
Treatment with water-based products that protect the wood from insects and UV rays, in addition to providing color and water resistance.
Water-based varnishes guarantee the wood's durability outdoors, provided there is no direct contact with the ground or prolonged exposure to moisture.
We offer a wide range of varnishes with transparent or opaque finishes. The transparent ones maintain the natural texture of the wood, while the opaque ones offer a matte finish, enhancing the color of the applied varnish.

Modified Term
The Modified Thermal Treatment process involves heat-treated wood that undergoes a process in which it is exposed to high temperatures (generally between 160°C and 230°C) in a controlled, oxygen-free steam environment.
This treatment is designed to improve the wood's properties, such as durability and resistance to environmental factors, without the addition of chemicals.
It is widely used outdoors for decking, facades, cladding and garden furniture, as it resists weather, fungi and pests well and is very stable. It can also be used indoors and is ideal for humid environments such as saunas, spas and areas around swimming pools, due to its low water absorption and resistance to deformation.
Risk Classes
In this image, we see a house that highlights the classification of the woods used in its construction, organized from 1 to 4 according to risk class. Hover over each number to read the legend with more information about each one.
Class 1
Situations in which wood is used inside a building but is not exposed to weather and humidity (parquet, cladding, etc.).
Class 2
Situations where the wood is covered and not exposed to the weather, but where it may be subject to occasional but not persistent wetting (roof structures, load-bearing structures, load-bearing wall structures, etc.).
Class 3.1
Situations where the wood is above ground and exposed to the weather. The products will not remain damp for long periods. Water does not accumulate (sheltered coverings, sheltered rooms but in a humid environment, etc.).
Class 3.2
Situations where the wood is above ground and exposed to the weather. Products will remain damp for long periods. Water can accumulate (cladding, screens, shingles, fences, pergolas, certain types of decking, etc.).
Class 4
Situations where the wood or wood-based material is in direct contact with soil and/or fresh water, or where the design leads to significant water retention (certain terraces, posts, soil retainers, sleepers, swimming pools, etc.).
