HAUFE ceiling systems

HAUFE ceiling systems can be easily adapted to architectural

requirements – as can be seen here at the University of Düsseldorf

by kadawittfeldarchitektur.

The thought-out HAUFE system

Whether light, acoustics, heating, cooling, or fire protection:

HAUFE ceiling systems integrate all essential in-house require-

ments. In addition, they allow the architect almost unlimited

creative freedom without dominating the ceiling’s visual

design through technical installations.

With our ceiling systems, the upper end of an interior space

becomes an expressive part of the architecture. As an owner-

managed medium-sized company, we are always close to your

project. For we believe: the architectural design does not have

to be subordinated to the possibilities of a component. We

rather adapt our components to the architectural needs –

and still provide the security of an industrial production, the

reliability of a mature system concept, and the flexibility of an

industrial manufacture.

Our experience

Since 1968, HAUFE ceiling systems have been supporting

the development of the contemporary architecture thanks

to ever-new slat and grid ceilings adapted to current

requirements. In the second generation, the company is

now headed by Managing Director Helmut Schmalseder and

his wife, Ute Schmalseder, née Haufe.

Our production site is located near Stuttgart. From here,

we maintain close contact with the architects and support

our customers with a competent planning service, which

is specifically designed for architectural requirements. This

constant and intensive exchange continuously leads to new

architectural questions and constructive challenges. HAUFE

responds to these with project-related developments, but

also with new ceiling systems.

Hence, over the years this resulted in a wide product

system and an abundance of ceilings specifically developed

for projects in close cooperation with well-known architectural

offices. Today, Ute Schmalseder is responsible for the internal

sales team, in addition to the commercial part of the com-

pany. Helmut Schmalseder is responsible for technology and

development.

Consulting – planning – implementation

Our way of working

Architectural excellence is always a result of planning quality.

That is why we rely on a detailed preparation and a perfect

implementation. Our employees are experienced in coordina-

ting the details of planning directly with the architect.

After we have answered all the questions with the architect,

we develop an accurate plan including all special solutions and

constructive details after the order has been received.

As soon as the plan has been approved, all parts are

prefabricated in our company. They are packaged and – as a

construction kit – punctually delivered to the construction site.

A HAUFE ceiling is not only built once it is on the construction

site. Its creation to perfection already starts with sophisticated

planning and precise production using technically advanced,

state-of-the-art systems. This guarantees the high HAUFE

quality. In addition, it considerably reduces the installation

time and provides the architect with implementation

reliability.

Installation through qualified specialists

Due to the clear system and simple installation, a HAUFE

ceiling can be installed quickly and safely by any specialist

company. However, we recommend specific installation teams

who have been trained and certified by us. They are working

within the entire German-speaking region as well as internati-

onally. This gives architects the freedom to choose an expert.

Esthetics and functionality

Modern architecture and rooms with a pleasant atmosphere

demand a high-quality ceiling system. Our aim is to meet this

requirement. This is why our customers’ wishes are constantly

incorporated into our products – as are our many years of

experience in the production of ceilings. The diversified

HAUFE program offers you a multitude of individual design

variants. For decades, we have been successfully manufactu-

ring high-quality slat and open-cell grid ceilings.

The HAUFE slat system

The HAUFE slat system is distinguished by its stringent and

exact linearity. The slats are very versatile and therefore offer

enough space for individual solutions – without you having to

forego the safety of a mature system.

The space between the slats as well as the carrier rails is freely

selectable. Both strip lights and recessed lights can be integ-

rated flush-mounted into the HAUFE slat ceiling. We can also

temper the slats and/or equip them with an acoustic effect.

For this reason, the HAUFE slat ceiling is the most successful

ceiling in our program.

Making structures visible

HAUFE open-cell grid ceilings are functional and vary the design

focus, depending on color and installation height.

Segmüller Pulheim | architecture office Kottmair

The combination of different luminaires with the HAUFE slats results

in a spatial tension.

Federal secondary school Gainfarn | Franz und Sue ZT GmbH, Austria

It perfectly adapts to a wide variety of deployment sites with

their different technical and constructional requirements. And

because the slats’ color design is almost freely selectable, the

HAUFE ceiling can be found in office buildings, conference

centers, and event rooms as well as in museums, sales areas,

and public buildings of all kinds.

Die HAUFE open-cell grid ceiling

The HAUFE open-cell grid ceiling is a proven product sys-

tem that has been used for decades in furniture stores and

shopping centers. Timeless design, high functionality, simple

planning, and a very good cost effectiveness characterize our

open-cell grid system.

New range of colors

With regard to colors, our slat and grid ceilings can be adap-

ted to almost every architectural requirement in our manufac-

tory department. We can also paint individual slats in special

color shades in order to allow for the accentuation of certain

ceiling areas or even for a uniform color gradient within a

ceiling pattern.

Volume instead of surface

A HAUFE system ceiling does not always have to be a flat

surface. Due to different profiles, but especially by variable

lengths of suspension brackets, the ceiling can also transform

into a spatial volume via the carrier rails. In addition, a HAUFE

ceiling can be hanged as an inclined hanging section. It can

even have the form of triangles or ellipses. In any case, we in-

tegrate all necessary acoustic and in-house services, regardless

of the tasks the architects assign to us.

Exact alignment

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.

The components of the slat ceiling

HAUFE slat ceilings are available as:

» U-slat ceiling standard (flat)

» U-slat ceiling acoustic (micro-perforated)

» V-slat ceiling

» Z-slat ceiling

The HAUFE U-slats are made of aluminum and either flat

(without acoustic effect), or micro-perforated (with acoustic

effect). The acoustic slats’ profiles are filled with a special

acoustic fleece. The profiles are 10 mm wide. The slat height

is 40 mm standard. Special heights of 50 or 70 mm are also

feasible. The material thickness is 0.4 to 0.5 mm.

HAUFE slat systems

Due to their profile, V-slats are more elegant and delicate.

In addition, they are slightly higher than U-slats. U-slats

and V-slats offer the same technial details and functional

advantages.

The Z-slats complete our product range. They are particularly

suitable for very large ceilings. Even with a slat spacing of 20

to 30 cm, the ceiling looks almost closed. The building services

above remain virtually invisible. Installations have to be han-

ged separately from the ceiling between the slats.

The carrier rails are used to fix the slats. They are installed at

a maximum distance of 1,500 mm and attached to the bare

ceiling with suspension brackets every 70 to 80 cm.

Our product innovation

Apart from acoustics, the indoor climate plays an impor-

tant role today. We faced this challenge and developed an

innovative system that can both heat and cool. This creates a

pleasant indoor climate which, in combination with micro-per-

foration and acoustic fleece, perfectly meets the requirements

of climate and acoustics.

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.

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.

V-slat system:

The entire installation height (slat and carrier rail) is 70 mm, inclu-

ding the suspension bracket 160 mm.

U-slat system with or without acoustic effect:

Material: painted aluminum

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

Technical data – carrier rails and end brackets

We define the distance of the carrier rails in a ceiling plan. It is usu-

ally 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 connected 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.

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.

End profiles or end brackets are available in three versions. These

are shown on page 45. They are suitable for slat and open-cell grid

ceilings.

HAUFE acoustic slats

Due to their micro-perforation, acoustic slats ensure a sound-absor-

bing effect in open spaces, creating a cozy atmosphere.

Doc Morris, The Netherlands | kadawittfeldarchitektur

Timeless – elegant – functional

In energy-efficient buildings with thermal activation of

building structures, high demands are placed on the room

acoustics. 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.

20 | | 21

In conjunction with sound-absorbing walls and floors, sound absorp-

tion 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 activa-

tion of building structures.

Technical data – absorber system

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.

Improvement of sound absorption

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.

ted 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 custom-

made and painted in the ceiling color.

Strip lights and luminaires are perfectly integrated in the ceiling

with the help of thorough preliminary planning.

50Hertz in Berlin | LOVE architecture and urbanism ZT GmbH (AT)

Creating individual highlights

Strip lights and recessed lights, specifically developed for HAU-

FE slat ceilings, as well as all commercially available lighting

systems can be integrated comprehensively in the system.

Especially strip lights, whose length can be freely chosen,

underline the linearity of the system ceiling.

Advantages of the HAUFE LED light channel:

» Can be laid endlessly

Inspection

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 in-

stalled. The inspection element can be removed upwards or downwards. For the down-

wards 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).

Fire protection – building services – sustainable building

HAUFE ceiling systems are the perfect fit for the use in DGNB-certi-

fied buildings, like at 50Hertz net quarter and their head office in

Berlin | LOVE architecture and urbanism ZT GmbH (AT)

Safety in buildings

The large free cross-section of our slat system facilitates the

installation of fire protection systems such as smoke detectors

and sprinkler systems on the bare ceiling of the building. The

ability to forgo the second layer means significant cost savings

for you.

Our systems are available in fire protection classes A2 and B1.

The surface-tempered slat system has fire protection class B1.

In the area of escape corridors, the slats can be planned wit-

hout the temperature control elements. In this case, the slats

have fire protection class A2.

Air-conditioning systems, cooling sails and technical building

services are also installed above the slats on the bare ceiling.

Supply air can be designed falling through the ceiling in the

upper area. Alternatively, the slot diffusors can be integrated

in the slats – as can be seen on the left.

With a HAUFE system, only a few installations are directly

attached within the ceiling system. Hence, a HAUFE slat ceiling

allows for a quiet, harmonious interior design. Our products

are a perfect fit for the use in DGNB-certified buildings (accor-

ding to the standard of the German Association for Sustaina-

ble Building).

HAUFE inspection | Design – acoustics – light – heating – cooling – fire protection Design – acoustics – light – heating – cooling – fire protection | Fire protection – building services – sustainable building

Slot diffuser

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 surface temperature control

Design – acoustics – light – heating – cooling – fire protection | HAUFE surface temperature control

Our idea

The three components air and surface temperature as well as

air humidity are crucial for a feeling of comfort. Once they are

in a perfect balance, we feel comfortable. Often, it is difficult

to combine all three requirements cost-effectively and with

an ambitious creativity. The high density on the bare ceiling

caused by building services installations requires revision-

friendly ceiling systems with as low a construction height as

possible. Especially in multi-story buildings, every centimeter

of ceiling height that can be saved means cash money for the

builder. Revision-friendly systems with a high free cross-section

allow the installation of fire protection systems on the bare

ceiling. Supply and exhaust air systems can function perfectly.

A comfortable oxygen concentration in the breathing air, ple-

asant room temperatures, and good room acoustics leverage

better concentration and relaxed working.

HAUFE and eco-componens have addressed this challenge

and, in close collaboration, developed a system that can heat,

cool, and also absorb sound. This results in a pleasant, healthy

room climate which, in combination with micro-perforation

and acoustic fleece, meets the requirements of climate and

acoustics.

Heating – cooling – sound absorption

Increased demands on comfortable room climate control

require heating systems which must offer a minimum level of

coziness. The surface temperature control is based on a radia-

tion principle comparable to that of solar radiation. The slats

are heated by integrated pipes filled with tempered water.

The slats release their energy rapidly into the room in the form

of infrared radiation – noiseless and without any draft effects.

When impacting on objects and people, the energy turns into

heat.

The system is characterized by its high energy efficiency as it

can be combined with regenerative energy sources. Energy

savings of more than 40 percent are feasible, compared to

conservative heating/cooling systems. The cooling capacity

reaches approx. 105 W/sqm (with Δt average cooling tem-

perature to room air temperature 10 K). The energy saving is

feasible with the same temperature sensation and also allows

an even temperature distribution with a short heating and

cooling time.

Our cooperation with eco-componens guarantees a smooth

and fast installation of the system. As a result, it is possible to

precisely plan various installations, the position of the heating

circuit manifold, and all other details, thereby creating a

uniform appearance of the ceiling. Border areas which are not

covered with tempering elements are equipped with slats wit-

hout the tempering pipes. Installers can be certified by HAUFE

and eco-componens in a one-day training program to be listed

as a qualified installer. Detailed assembly instructions support

the technician during installation.

HAUFE special developments

HAUFE slats don’t have to be used for ceilings only. In 2016,

kadawittfeldarchitektur implemented the system in the gas

and steam turbine power plant Lausward near Düsseldorf on

the ceiling, but additionally as a wall cladding. It extends to a

height of 60 meters.

From rigid to flexible

Our slat systems have been developed as classic ceiling liners.

However, time and again creative architects use them in an

unconventional manner. Thanks to our openness to new

ideas and our close contact with the designing and planning

architects, we are also able to realize innovative architectural

ideas. For example, the slats were implemented as an extensi-

ve 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 characteris-

tics of the aluminum rails set natural limits. Nevertheless, at

HAUFE ceiling systems, we are fond of moving those bounda-

ries a little in cooperation with architects, time and again.

HAUFE open-cell grid ceilings

Detailed view of facing panel with full module

Square – practical – endless

The open-cell grid ceilings have been part of our offering for

decades. They are especially characterized by their timeless

design and high functionality. The open-cell grid ceilings are

predominantly found in furniture stores and shopping centers.

The HAUFE open-cell grid program distinguishes between

two variants. Type TE15 is inserted into a standard T-rail

system as a compact element. Its slat width of 15 mm

allows the T-rail system to be fully integrated so that it can

no longer be distinguished from the elements. It provides

these advantages:


» Quick installation due to year-long experience of technicians

» Powerful appearance

Type P-10 consists of elements and an internal substructure.

Due to the slat width of 10 mm, this system appears more

filigree. It provides these advantages:


» Inexpensive, the substructure is included in the price

The open-cell grid ceiling type TE15

The installation of the TE15 system in a substructure of T-rails

guarantees a cost-effective and high-quality implementation.

Simple and clever

The HAUFE open-cell grid ceiling type TE15 consists of grid

elements with circumferential frames, which are inserted into

15 mm wide T-rail substructures from USG or CMC or other

manufacturers. On request, the substructure can be obtained

from us or from the specialist trade.

The open-cell grid ceiling can be easily inspected, it is non-

corrosive and dust-repellent. It corresponds to fire protection

class A1 and is installed with continuous assembly.

Above the system, smoke detectors, sprinkler systems, and

building services can be installed on the bare ceiling. Due to

the high free cross-section, their functions remain unchanged.

The entire system can be hanged several meters from the bare

ceiling.

Technical data – open-cell grid ceiling type TE15

The elements have a slat width of 15 mm, the frame is

slightly recessed. The element size is basically 600 x 600 mm or

625 x 625 mm.

Open-cell grid ceiling type P-10

The installation of luminaires or spotlights is carried out via

modular panels, which are flush with the grid element and

custom-made.

Filigree and inexpensive

The open-cell grid ceiling type P-10 consists of grid elements

as well as carrier and transverse rails. The profiles have a slat

width of 10 mm, wall connections are realized with angles

made of the same material. The element sizes are standar-

dized to 600 x 600 mm or 625 x 625 mm.

As a result, commercially available luminaires seamlessly fit

into the system. Custom sizes are also feasible. These are usu-

ally determined by us on the basis of the layout. Due to the

exact determination of the material quantity for the room,

you’ll save installation costs for additional cuts and will have

only a small amount of material waste.
