GRECA are polycarbonate multiwall corrugated sheets with an honeycomb structure and a cover width of 1000 mm. Sheets have been developed for lateral overlaps to most insulated panels and / or corrugated metal sheets available on the market. Designed for the installation of skylights both in single and multiple applications, thanks to the possibility of longitudinal and / or lateral overlapping, they are also available in thermocurved version (except GRECA 250/75), with bending radii of 3500 mm or 6000 mm.
The side wing has a multiwall structure to reduce the problem of condensation. GRECA sheets have a good light transmission and, thanks to their coextruded UV protection, they guarantee a high degree of protection against UV rays, yellowing and hail damage. The corrugated shape provides good resistance to external loads (snow and / or wind), while the typical polycarbonate features provide excellent resistance to accidental shocks and temperature leaps. The system is completed by a range of accessories that complete the installation.
