Tronsole®
type
Z
Load-bearing impact sound insulation element for connecting landings to staircase walls. The element transfers positive shear forces. Depending on the configuration, the element also transfers negative shear forces and lateral horizontal forces.

Advantages
Outstanding soundproofing
SSt III to VDI 4100 is achieved in a standard apartment building with all Tronsole® types − and also DEGA class A with certain product typesReliable and comparable sound attenuation values
Acoustic characteristic values of Schöck Tronsole® tested to DIN 7396; describes a method of measuring impact sound insulating elements for solid stairs and landings and enables comparison of decoupling elementsAcoustic characteristic values tested to DIN 7396
Evaluated impact sound pressure level difference ∆L*w, landing ≥ 27 dBType-tested load-bearing element
With integrated spacers for reliable and straightforward installationMore flexibility
Additional product variants available for uplift and horizontal forcesUndisrupted joint pattern
When installed, Tronsole® type Z is no longer visible on the underside from a landing thickness of 180 mm and is fully concealed by the landingConnecting frame on all sides
For acoustic-bridge free connection to Tronsole® type L joint plate- Certified fire protection
Satisfies fire protection requirements up to R 90 (with load-bearing element Z Part T); use in rescue routes confirmed by fire performance assessments
