Modern villa with extremely secure sliding windows

The safest frameless sliding windows

Sliding windows from swissFineLine combine the desire for modern, light-filled architecture with the need for maximum security.

The desire for outstanding architecture with extensive glazing and the need for safety and security are no longer incompatible. swissFineLine Protect offers a standard of security for windows once thought impossible .

With burglary protection in resistance class RC4, bullet resistance in class FB6-NS and the seamless integration of smart monitoring technology, these frameless windows offer a higher level of protection than ever before.

This opens up a whole new range of architectural design possibilities. Large-format, moveable window façades and secure interior glass elements can be combined with high standards of property and personal protection without any compromises.

By connecting safe, ultra-transparent high-tech glass with innovative frame technology, the Swiss manufacturer has designed the safest frameless windows on the market.

swissFineLine Protect – transparency in its safest form.
