Silentium 100
Rw 52 dB
The complete Silentium 100 partition (profiles, gaskets, double glazing and junctions) was built into the test opening of an accredited laboratory and measured to ISO 10140-2. The single-number rating to ISO 717-1:2020 is Rw 52 dB.
Laboratory tested
52Rw dB
C −1 · Ctr −4
Rw is the weighted sound reduction index: a single-number laboratory rating of airborne sound insulation. C and Ctr are the spectrum adaptation terms for mid-frequency and low-frequency dominated noise.

What this figure covers, and what it does not.
Laboratory tested: Measured on the complete assembly at an accredited laboratory. Report reference published.
- The figure is a laboratory value for the tested specimen described above. It is not a glass-only rating and not a calculation.
- Other glass build-ups, heights and junction conditions are assessed per project; the tested result is not transferred to a different configuration without engineering review.
- Performance measured on site (for example DnT,w or R′w) depends on installation quality, flanking paths through floor, ceiling and façade, and room conditions. No site measurement is claimed here.
- Door-sets within a partition run have their own acoustic performance and are not covered by this report.
