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.

Carrier rails


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.


HAUFE LED light channel

Technical data:

Advantages of the HAUFE LED light channel:

» Can be laid endlessly

» Construction height without power supply 25 mm,

with power supply 60 mm

» Installation on the carrier rail, no interruption of the

carrier rail required

Light channels can be placed on the carrier rails front-mounted.

This can save costs for the additional suspension of the lights.

For lengths of more than 1,490 mm, the carrier rails must be

interrupted for lamps with a height of more than 25 mm.

Modular panels / spotlight panels

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.
