Sandwich panels Clearpet

CLEARPET is a lightweight sandwich panel with a PET foam core and skins in a fi breglass impregnated with epoxy resin. The sandwich panels made with foam cores allow to reduce the thickness of the stone slab, obtaining lighter but equally resistant tops and coatings. PET foam is almost white. This foam core glued to a clear fi breglass permits to create a light surface maintaining the visual characteristics of the panels. Pet core is completely made of recycled material.
