The safest sliding window. Worldwide.

With maximum burglary protection, security-monitored multi-point locking and bullet resistance, swissFineLine guarantees maximum personal and property protection.

So your window is able to resist even extreme burglary attempts. 


Minimal profile widths – maximum views

There is no visible frame, only the centre profile with a minimal face width of just 24 mm, thus providing unimpeded views and maximum daylight for a light-flooded living experience.

Unmatched operating comfort

swissFineLine excels with its outstanding operating comfort. The sliding element glides along the maintenance-free roller track with hardly any noise. The swissFineLine drive can be used to open sliding windows of up to 1200 kg automatically at the push of a button.

Unequalled dimensions

swissFineLine supplies element sizes of up to 20 m2 thus enabling openings in rooms of unequalled dimensions. In this system, the glass acts as a self-supporting structural element which makes it possible to completely omit any framing.

Excellent energy balance

In terms of thermal insulation and energy efficiency, swissFineLine is exemplary and complies with the exacting Minerige and Minergie P standard (Passivhouse standard).

Perfect integrity and weather protection

The system boasts class-leading values for air permeability (Class 4), resistance to water penetration (Class 9A) and resistance to wind load (Class C2/B3).

Unique safety protection and sound insulation

swissFineLine offers the greatest degree of security (class RC2,RC3,RC4). With an Rw value of 46 dB, swissFineLine provides excellent sound insulation properties across the entire frequency range without additional measures.

These figures relate to the respective test elements and may vary depending on the type of element.
