The thermo-insulating wall panels concealed-fix CORE are composite, self-supporting structural elements, consisted of two profiled sheets bonded in an insulating rigid foam core of polyurethane (PUR) or polyisocyanurate (PIR).
The fastening screws of the panels on the metal frame of the building due to the specific configuration of the joints are invisible. They are used for covering the facades of buildings in vertical and horizontal positioning.
Are conformed to the European Standard EN 14509: 2013 and are CE marked.

ECOPANEL WLC is the premium type of CORE wall concealed-fix panels. The outer face is of four different shapes “microline”, “polyline”, “waveline”, “flat”, and the inner face is slightly shaped “standard” or “flat”. They are produced in nominal thicknesses of 40mm - 50mm - 60mm - 80mm - 100mm - 120mm. The thickness of the sheets ranges from 0.40mm to 0.60mm and the coatings as well as the color shade of their external side depend on the specific needs of each project.
Special features
- Modern external aesthetic facade.
- Secured concealed fix joint by a normal fastener, which holds both external - internal sheets.
- Factory - fitted foam tape in the female side for a greater jointing sealability.
- Aluminium foil strip, less gas escapes from the polyurethane cells thus ensuring good conductivity for longer.
- Polyurethane foam core CFC Free & HCFC Free. Harmless to the environment and safe for the ozone layer.
