CORKPAN is a totally natural cork panel because it is obtained through a thermal roasting process, therefore without the addition of glues or chemicals.

The thermal roasting process allows the melting of the resins naturally contained in the bark, which act as a natural glue to aggregate the granules and form the panel.

Roasting does not alter the characteristics of the cork , on the contrary it improves them , as it allows the granule to expand, without incorporating air and improving its insulation characteristics .

The brown color of the product is not due to an alteration of the cork but only to its roasting.

The CORKPAN panel guarantees high fire resistance and excellent dimensional stability – even in contact with water and humidity. CORKPAN has no “duration” limits and maintains its performance over time.

Thermal conductivity tested  at 10 ° C: λ D =  0.039 W / m ° K  (sample taken from cold rooms  after 45 years of use ).
