OLEOTHERMY PROCESS :


Combining timber with vegetable oils, this oil heat treatment process developed by OLEOBOIS ® and fine-tuned by the CNRS (French National Centre for Scientific Research) and CIRAD (Centre for International Cooperation in Agronomical Research for Development) is based on ancestral techniques involving the oiling of timber. This consists of a variety of wood species (Douglas fir, larch, oak, chestnut, etc.) soaking in and absorbing a mixture of vegetable oils and natural additives heated at low temperature (<150°C). The use of vegetable oils possessing fungicidal properties gives the treated wood water-repellent properties, which increase its durability. This innovative absorption technique provides a healthy material that conforms to "Haute Qualité Environnementale" (High Environmental Quality) criteria, from production through to recycling.

Applications:


Oleothermy is carried out on all types of profiles for weather-boarding, planking, deck boards, fascia boards, fencing, etc.

Benefits:


This oleothermy timber treatment offers an alternative to chemical treatments while maintaining the wood's aesthetic and natural characteristics.

Characteristics:


This "oleothermal" (oil heat treatment) process consists of three separate phases, each of which performs a different role.

phase de chauffe

The heating phase vaporises the water in the wood, creates a pressure state and reduces the internal stresses in the material.



phase de refroidissement

The cooling phase condenses the water vapour, which causes the formulated oil to be deeply absorbed.



phase de séchage

The air-drying phase finalises the absorption and quickly produces a dry appearance.
