Building projects and therefore
planners and the companies carrying out the construction work havebeen subject to steadily increasing requirements in recent years.
This is particularly true for timberconstruction.
Innovative products and new approaches take care of these requirements,
making timber construction one of themost promising industries in the construction sector. On top of that, timber
construction offers advantages suchas quick construction times, negative
carbon footprint, precision pre-fabrication and low dead weight.

Comfort is more than justminimum sound insulation

The level of sound control should
be defined as early as the planningphase. The national minimum requirements given in the standards
often do not provide the level ofcomfort that people expect.
Sylodyn® bearings move properties
into the comfort zone. DEGA recommendation 103 helps you choose theright sound control class.

Highly effective Sylodyn®
material
Sylodyn® is characterised by its dynamic properties and durability. It isresistant to moisture, oils and greases
commonly found on construction sites
and has proven itself both in real-life
applications and at testing institutes
for decades. All this makes it the ideal
bearing material for joints.

Sound bridges must be avoided during planning and implementation.
Therefore, the right fasteners must
be selected in addition to the highlyeffective Sylodyn® strips. These fasteners must be acoustically optimised and structurally verifiable.
For this purpose, Getzner cooperated
with established partners in the timber
construction industry to develop solutions for angle brackets, screw connections and plug-in connections.

Sylodyn® solutions for element construction
and modern modular construction

Optimally decoupledmodules
Due to increasing time and budget
specifications, modular construction
methods gain more and more ground in
the building and construction industry.
This requires certain measures during
planning which offer a wide range ofadvantages at the implementation.
Acoustic decoupling with Sylodyn®
prevents impact noise and airborne
sound being transmitted from one
module to another. This also enables
optimisation of the floor construction and, in many cases, weight reduction. Sylodyn® itself is highly effective
even with a small bearing thickness(6 or 12 mm). Sylodyn® can also be purchased in a self-adhesive version foreasy pre-fabrication.

The ultimate quality
requirements in element
construction
For many years, Getzner has developed
solutions with research and development input from leading manufacturers in the timber construction industry.
These solutions have also been tested byindependent institutes (EMPA, Rosenheim Technical University of Applied
Sciences, Holzforschung Austria).
Wether solid wood structures, frameor panel construction or cement-bonded wood fibre composite constructions,
Sylodyn® from Getzner and the associated fasteners give planners maximum freedom without having to sacrifice sound control.

Getzner is a reliable,experienced partner
Solutions from Getzner have beensuccessfully used in timber construction
since 1998. Alongside the Sylodyn® andSylomer® materials, Getzner has also
helped to develop detailed designs
for smooth installation or easy-to-fit
adhesive versions.
A dense dealer network made up of
established partners means our customers can rely on quick and punctual
delivery, anytime.

They are true vibration protection experts:
You can not only rely on the sound control
solutions but also on their consultancy service.

Suspended ceilings offer the optionof improved sound control, particularly for renovation projects, but also
for new buildings. Getzner provides
support, both with elastic ceiling hangers as well as with elastic mounts forfalse walls.

Selecting the right flooring system iscrucial when it comes to the acoustic
effectiveness of a ceiling. Getzner offers
the Acoustic Floor Mat and Acoustic
Floor Block products for dry and wet
screed, along with highly effective
solutions for hollow floor systems,
terraces or renovations of existingceilings for reducing impact noise.

Due to the lower mass of timber constructions, decoupling from building
service equipment is very important.
Using Sylomer® and Isotop®, facilities
are acoustically decoupled from thebuilding structure and disturbing vibrations are reduced. This also reduces
unwanted sound radiation in adjacentrooms.
