uPVC-Alu: Compact Design, Solid Performance

The KF 310 combines slim construction with modern aesthetics and robust functionality. Its protective aluminium cladding and sculpted sash create a clean, contemporary appearance that suits a wide range of architectural styles.

Security is reinforced with I-tec Glazing, which bonds the glass pane around the entire perimeter—significantly increasing stability and resistance to forced entry. Paired with RC2 security options and fully concealed locking, the KF 310 provides strong, discreet protection.
