A pleasant revolution has begun in furnishing. New composites with the most different materials can be created to make lighter, more resistant, workable and easier to install pieces of furniture and architectural structures, without changes anything in their appearance. This is possible thanks to Eulithe®: the “core” to fit out! The pleasant revolution consists in the use of Eulithe® coupled with MDF or HPL panels, which allows to work the so obtained composite as if it was a standard chipboard. The use of screws, hooks, hinges etc. and surface finishing remain unchanged compared to traditional woodworking; furthermore, final weight is at least one-third of the traditionally made furniture. For this application, we recommend the use of Eulithe® with a variable density from 80 to 150 kg/m³.
