Our new technology with a sustainable soul is Varnishless – based on wood being heat treated. The name Varnishless Technology relates directly to the absence of varnish used in the making of this type of closure head.
The thermal treatment of wood is made up of three phases.
1. Drying: The wood is dried at a high temperature while its humidity is maintained at a constant level to reach the desired grade of drying.
2. High-temperature treatment: Once the wood has reached the correct humidity level, thermal treatment begins. This is when the wood is heated to a very high temperature, depending on the level of desired coloration.
3. Cooling: The conditioning and cooling phase allows the wood to stabilize.
Heat treated wood gains a completely natural look when finished, without the use of any chemicals or the need for any further processing.
Through the Varnishless technology, heat-treated wood undergoes improvements to its durability, stability and strength. The resilience that wood acquires – over 20 times greater than untreated wood – makes it more resistant to mold, fungus and insects.
