Technical data sheet – U-slat micro-perforated (acoustic slat)
The sophisticated system perfectly adapts to the functional
requirements of today‘s building culture. Technical building
services and fire protection systems work invisibly in the back-
ground.
The inspection-friendly system provides easy access to
installations on the bare ceiling. Low system heights, a wide
range of colors and a sophisticated light concept complete the
system. Worldwide, modern offices, venues, museums, sales
areas and public buildings are equipped with our system.
With a free cross-section of 80 percent and a sound
absorption value (sav) of 0.35 (H), the acoustic slat is the link
between a good climate and pleasant room acoustics. The
slats are micro-perforated and equipped with a special profile
filling of sound-absorbing acoustic fleece.
This results in a full-area absorption of the room sound.
Due to the notably large free cross-section, the air from the
building services installations can descend spatially through
the ceiling. In contrast to the conventionally circulating air, air
falling from above is perceived as particularly pleasant. This
prevents the effects of drafts.

U-slat system with acoustic effect
Technical data:
Material: painted aluminum perforation 0.7 mm
Material thickness: 0.4 – 0.5 mm
Slat height: 40 mm (50 – 70 mm on request)
Slat width: 10 mm
Standard colors:
Slats: RAL 9016, 9003, 9005 and 9006, special
colors according to RAL and NCS available
on request
Carrier rails: RAL 9005 or in slat color
The slat distance (measured from axis to axis) is called a
module. Here are several examples. However, the module
can also be defined individually. The free cross-section
defines the free space to the bare ceiling.

Acoustic effect
In conjunction with sound-absorbing walls and floors, sound
absorption values (sav) of sav = 0.35 (H) according to the
German standard DIN EN ISO 11654 facilitate perfect room
acoustics, without influencing the climatic characteristics of the
thermal activation of building structures.

Sound absorption with acoustic slats

Absorber system
As an accessory, we offer an absorber system, which is
integrated into the substructure of the slat ceiling. It is
available in different variants and allows an additional
improvement of the sound absorption in the room.
The slat system still offers a free cross-section of 80 percent.
However, this facilitates a sound absorption value of 0.3 - 0.6.
As a matter of fact, our slat systems can also be covered
with a panel with acoustic effect (e.g. from Rockfon
company). Doing so, you can achieve sound absorption
values of up to sav = 1.0 (H). However, this closes the
system. Hence, fire protection installations must be
implemented in a second layer.
HAUFE acoustic absorbers can be installed in the course of the
carrier rail as well as in the direction of the slat. Their fixing is
accomplished either between the suspension brackets directly
on the suspension wire, or they are placed on the carrier rails
and fastened with special brackets between the suspension
wires.

Slat connector
The slat connector is pushed into the carrier rail with the closed
side facing upwards into the press cut. Then the slats are
clipped into the carrier rail from both sides. Finally, the
connector is pushed into the slats.
End brackets slats
As a rule, the slat ends with a 2 cm shadow gap to the wall.
The slat can protrude up to 30 cm. In order to close an open
ceiling edge in the room, an end bracket can be installed in the
slat from above.
Carrier rail connector
We define the distance of the carrier rails in a ceiling plan. It is
usually determined by the arrangement of the lights and the
fittings of air-conditioning systems, electrical installations, etc.,
which are located on the bare ceiling. The carrier rails are con-
nected in their length with rivets 3 x 6 mm or with screws.
The maximum carrier rail distance is 1,500 mm. The distance
between the individual suspension brackets should be between
70 and 80 cm. It is mandatory that the slat edge joint is situated
on a carrier rail. Both slats are fixed with a slat connector in the
carrier rail and justified in longitudinal direction.

Recessed lights are fitted into the slat system using modular
panels. These can be obtained from us. The modular panels are
custommade and painted in the ceiling color.

Inspection HAUFE slat system
Inspection options
Basically, the HAUFE slat ceiling can be opened very easily.
The slats just need to be compressed a little and then detached
from the carrier rail brackets. In order to open larger areas
without removing the slats, a downward opening inspection
flap can be installed. The inspection element can be removed
upwards or downwards. For the downwards removal,
the carrier rail is cut flat and equipped with four bolts.
The inspection flap can be opened downwards by simply
unlocking it. It is fitted with two additional carrier rails,
which hold the flap slats. They are provided with latches
to open and close the flap. The maximum size of the
inspection flap is 80 x 80 cm (other sizes on request).

Slot diffuser
Integrated slit outlets in slats
To supply the rooms with fresh air, slot diffusers with variable
adjustment options can be installed between the slats.
The slot diffusers are hanged separately from the ceiling.
In order to avoid breaks in the carrier rails, dummy elements
can be used to underpass the slot diffusers below the carrier
rails. Manufacturers’ notifications are available on request.

HAUFE special developments
From rigid to flexible
Our slat systems have been developed as classic ceiling liners.However, time and again creative architects use them in anunconventional manner. Thanks to our openness to newideas and our close contact with the designing and planningarchitects, we are also able to realize innovative architecturalideas. For example, the slats were implemented as an exten-sive wall cladding recently.
Who says a linear structure must always consist of parallel,
straight lines? Our slat systems even facilitate fan-shaped
structures on the ceiling. Of course, the material characteristics
of the aluminum rails set natural limits. Nevertheless, at
HAUFE ceiling systems, we are fond of moving those boundaries
a little in cooperation with architects, time and again.
