The 20000 series aluminum frames combine all the advantages of the 18000 Ultra K system with a revolutionary thermal break system that provides unmatched insulation across all available configurations.
In the top-quality frames of the series, the polyamide thermal break is enhanced with cast polyurethane, resulting in an exceptionally low thermal transmittance coefficient (Uw) starting from 0.87 W/m2K, depending on the number of glass panes used. Thanks to the ability to install up to four insulating glass panes and the application of two EPDM gaskets around the perimeter, high sound insulation, waterproofing, and air tightness are ensured.
Another advantage of the series is the use of the advanced German Roto NT opening mechanism. This high-precision and durable mechanism allows for simultaneous locking at up to 14 points, depending on the size of the window, providing security and protection.
The 20000 casement windows are combined with insect screens, shutters, or roller blinds and are an excellent choice for any modern home or commercial space.
