Concrete stairs
Getzner solutions made from
Sylomer® effectively decouple concrete and lightweight stairs, ensuring greater peace and quiet.

P

eople make noise when walking
in buildings, which can be transmitted to adjacent rooms as structure-borne noise. Stairs in particular
are frequent sources of noise. The
elastic decoupling of flights of stairs
and landings significantly reduces thetransmission of structure-borne noise
to nearby rooms via adjacent walls andceilings, resulting in a reduction in theoverall noise level in the building.

The Getzner SB10 bearing for
concrete stairs is a combinationof a Sylomer® strip and foam.
Advantages— Solutions for in-situ concreteand precast concrete stairs— Outstanding impact noise
reduction (31 dB) at minimal
installation height— Quick and easy installation
thanks to flexible design— Compensation of construction
tolerances— Accurate load transmission
and low deflection

Details
To avoid sound bridges, the stair flightmust be completely separated fromthe support structure.
Installation and delivery dimensions
The Sylomer® SB10 bearing is delivered in stripes of 1.5 m. Thanks to
the flexible product design, it can beeasily adapted to the on-site requirements. A clean and even surface aswell as the implementation of thejoint between the concrete stair andsupport structure are especially important to guarantee effectiveness.

Lightweight stairs
Elements made from Sylomer®
decouple lightweight stairs fromthe support structure.
Advantages— Solutions for common
lightweight stair designs— Proven impact noise reductionof 29 dB
— Decoupling of low frequency
ranges, even below 100 Hz— Simple type selection— Sustainable damping efficiency
due to the excellent long-term
behaviour of Sylomer®

Details
Connections to walls and ceilings
must also be decoupled. Getzner
offers suitable detailed solutions forthis purpose.
Installation and delivery dimensions
Decoupling elements made fromSylomer® are available in different dimensions and can be installedboth on-site and on the stairs prior to
installation of the staircase. Screwfixings on the stairs should also be
decoupled using elastic washers inorder to prevent sound bridges.

Tests
All stair bearings from Getzner havebeen successfully tested with regard
to their effectiveness on modern test
rigs for stairs and with on-site measurements. In addition, Sylomer® bearings have already been successfully
mounted on staircases for over threedecades, with more stringent requirements on impact noise protection being met even under the most challenging conditions.
