Sandwich panels with foam cores are realized to reduce the thickness of the stone slab used, obtaining much lighter but equally resistant tops and coverings. The clearness of the PET foam and fibreglass permits to create a light surface maintaining the visual characteristics of the panels.
CLEARPET is a lightweight sandwich panel with a PET foam core and a fibreglass skin impregnated with epoxy resin. PET panels have a recycled material core
A - SKINS IN GLASS FIBRE FABRIC
Impregnated with epoxy resin 680g/m²
B - PET FOAM CORE
