Acoustic Floor Mat— The ideal solution
for all situations
Getzner’s products are highly effective and cost-efficient solutions
made of foamed polyurethane designed to reduce impact noisetransmitted through floors. They
provide highly resilient impact noise
protection in commercial and industrial premises, as well as in residential and public buildings.

The Acoustic Floor Mat is installed asa full-surface layer below the screed.
Only a few millimetres thick and ina range of different types, the floor
mats achieve between 21 and 35 dB
impact noise reduction, or up to 38 dB
as a double layer.

Range of use

The Acoustic Floor Mat is delivered
in convenient sheets. The mats are
installed as a full-surface layer, profiled side facing down and seamless,on a level foundation. A film is usually laid on top of this as a vapour
barrier. The screed can then belaid directly on top of these layers.
For further information on installation, please see the installation
instructions.

— Supermarkets— Fitness centres— Hospitals— Commercial kitchens— Production halls
and warehouses— Hotels— Nursing homes— Schools anduniversities— Concert halls— Libraries

Details
To avoid sound bridges, the screed
must be completely separated fromthe support structure. Edge insulation strips are used for this purpose. Pipe openings must also bedecoupled.

ΔLw in dB— Impact noise reduction ofup to 35 dB (ISO 717-2)— Consistently high impact
noise insulation across theload range and service life
— Load range up to 5000 kg/m2— Extremely low deflection,even under high loads— Free from softeners— Resistant to ageing, rot-proof,
resistant to chemicals andodour-free— A+ classification for indoor
air quality— Easy handling and quick installation thanks to low weight

Acoustic Floor Blocks for
impact noise protection indemanding situations
Efficient decoupling with a low
installation height

Acoustic Floor Blocks –Quality for the most demanding situations
Point bearings from Getzner are
particularly suited for rooms withdemanding sound control requirements. That is why they are often
found in buildings such as recording studios, cinemas, nightclubs
and gyms. However, car parks, luxury apartments and hotel rooms canalso be effectively decoupled fromunwanted surrounding noise.

The homogenously foamed bearings
made from Sylomer® stand out due totheir proven effectiveness and durability. The range, made up of variousmaterials, provides the perfect solution whatever the application. They
can be used under both dry and wetscreeds and offer planners and fabricators an economical form of impact
noise protection.

Proven effectivenesseach. They are installed according
to the previously defined grid plan.
If necessary, the cavities between
the bearings can be insulated withmineral wool. The Acoustic Floor
Blocks are fixed in their positions
using the corresponding profile
rails or drywall panels. Dependingon the type of implementation, it
is possible to use either a floating
screed or drywall panels of the appropriate strength.

Range of use— Cinemas— Recording studios— Concert halls— Fitness centres— Theatres— Conference centres— Nightclubs— Dance studios— Bowling alleys— Schools

Details
Edge insulation strips from Getzner
prevent sound transmission between the floating screed and adjacent components, such as walls,
supports or pipe openings. They
are therefore an indispensable addition to the AFM and AFB products
for floating floors.
