Case Study
Lightweight Stair Bearing in a terraced
Housing Complex, Munich (DE)Proven impact noise reduction
due to elastic bearing of thestairs

Reduction of structure-borne noisein the neighbouring residential units

High effectiveness and durability
over decades

Greater Impact Noise Protection forincreased Comfort Levels in the Home

Description of the project The solution
A total of 78 harp stairs made fromwood and steel were installed with
impact sound control for 26 residential units.
hen building the new terraced
housing complex in Perlach,south-west of Munich, the renowned
company Fuchs-Treppen was responsible for installing the staircases. A
top-quality indoor environment requires effective protection against
sound transmission. As lightweightstairs particularly facilitate thetransmission of impact noise, bearings made from the elastic materialSylomer® were specially developedby Fuchs-Treppen and Getzner.

W

Stair specialist Fuchs and vibrations specialist Getzner enjoy apartnership stretching back overmany years. Together they havedeveloped the perfect solution.
he elastic bearing of stair ﬂights
has a signiicant inﬂuence on
the reduction and transfer of structure-borne noise to the surrounding
residential units.

TWith lightweight stairs, the bearing
points on the ceiling and walls areelastically decoupled. Laboratory
experiments have shown that thismeasure signiicantly reduces thetransmission of impact noise intoneighbouring rooms.

Proven noise protection
What was proven in the laboratory has
been conirmed in practice: during
acceptance tests, the stairs developedby Getzner and Fuchs-Treppen fulilled
the strict requirements of increased
sound protection for raised comfort
level.
Simple installation
The appropriate decoupling elements
for the respective type of stairs aredelivered and only need to be installed on-site. This guarantees fastand simple installation.

Feedback
Effective for decades
The decoupling of the lightweightstairs has paid off in a number ofways for both the developers and residents of the new complex. The signiicantly improved comfort levels due toless structure-borne noise also contribute to the value retention of theproperty. Thanks to the high productquality and durability, Sylomer® even
impresses after many decades withlow deﬂection and eficient vibration
isolation.

“It is simply staggering that impact noise onlightweight stairs can be reduced so much.”

What does the client have to say
about the project?
“Just like our customers, we also value excellent sound control. The demands and challenges for this haveincreased signiicantly in recent years.
We have had outstanding experienceswith the sound control bearings fromGetzner which we have installed in
our projects. The consistently positive
feedback from our customers has impressed us.”
