1. Definition of Project and General Details

1.1 Definition of project

SUNFLEX Aluminium Systeme GmbH, Wenden, manufactures and sells (among others)

folding-sliding-systems which can be used as partitions in the interior of buildings but also

can for closing off heated living quarters from the outside area. The system to be tested, type

SF 75H, is a glass folding wall consisting of 3-layered laminated timber in which different in-

sulating glass units up to a thickness of 40 mm can be fitted. The three-winged wall is

equipped with ceiling and floor rails integrated in the system and has vertical seals at the

wing joints as well as horizontal seals above and below on the ceiling and floor rails.

The system SF 75H was installed in the test stand and tested with respect to the airborne

sound insulation. For this purpose, the construction has to be installed in the test opening

with dimensions width x height = 2,400 mm x 2,200 mm in the test stand with suppressed

flanking transmission in accordance to DIN EN ISO 10140-5.

The airborne sound insulation in a functional state of the test object manufactured by the cli-

ent in accordance to DIN EN ISO 10140-2 was to be ascertained.

DIN EN ISO 717-1 “Acoustics – Rating of sound insulation in buildings and of build-

ing elements – Part 1: Airborne sound insulation”

(ISO 717-1:1996 + AM1:2006) “; German Version EN ISO 717-1:1996 +A1:2006

Test Report 1485-001-14, 29.01.2014/sg-gm


2. Set-up of Test Objects and Test Arrangements

2.1 Laboratory

The sample element was installed in the test stand belonging to the test institute by the

manufacturer’s fitters in order to ascertain the airborne sound insulation with suppressed

flanking transmission in accordance to

DIN EN ISO 10140-5.

The maximum sound reduction index R`max of the test stand when a type A wall (lightweight

wall) was installed in accordance to DIN EN ISO 10140-5, Appendix A.2.2.1.1 amounted to:

fTerz in Hz 50 63 80 100 125 160 200 250 315 400 500

R`max in dB 29,2 40,8 34,6 44,1 44,3 49,6 55,7 59,6 61,6 63,8 68,1

fTerz in Hz 630 800 1000 1250 1600 2000 2500 3150 4000 5000

R`max in dB 70,6 72,0 75,1 74,6 73,2 73,3 78,7 83 86,2 90,5

The rated sound reduction index amounted to:

R`w, max = 68 dB.

The enclosing wall of the folding-sliding-system was manufactured by skilled test institute

employees. In order to achieve an adequately high level of sound insulation, the wall panels

of the altogether approx. d (= thickness) = 500 mm thick wall were built up on both sides of

the butt joint with freestanding metal stands.

Test Report 1485-001-14, 29.01.2014/sg-gm


2.2 Set-up of test object

The tested sample element was an folding-sliding-system in timber composite construction

made of sections having a thickness of 75 mm with floor and ceiling rails as well as door

stops and 3 wings equipped with insulating glazing units (2 different types). The folding-

sliding-wings which are connected with one another are moved through a roller carriage sys-

tem which is adjustable in height in a ceiling rail and/or floor rail. The connection to the side

wall connection is carried out with a vertical connection profile. The dimensions of the total

element amount to width x height = 2,400 mm x 2,200 mm. The test surface amounts to ap-

prox. S = 5.28 m2.

The glazing units have the following construction characteristics:

Build-up (according to sticker on glass):

VSG SI 8 mm

Cavity between inner and outer pane (SZR) 16 mm (Argon)

LE Premium 6 mm

Build-up (according to sticker on glass):

Float 4 mm

Cavity between inner and outer pane (SZR) 20 mm (Argon)

LE Premium 4 mm

The following build-ups were tested:

Measurement 1:

Folding-sliding-system SF 75H,

Glazing (build-up 1): VSG SI 8 mm, SZR 16 mm (Argon), LE Premium 6 mm

Measurement 2:

Folding-sliding-system SF 75H,

Glazing (build-up 2): Float 4 mm, SZR 20 mm (Argon), LE Premium 4 mm

The surrounding joints between test object and test opening were sealed using silicon com-

pound or with durable elastic filling mass respectively.

The detailed build-up of the construction can be seen in the manufacturer’s construction

drawing, annexes 1 to 6. Annex 7 shows the construction characteristics of the glazing units

(stickers on glass). Annexes 8 and 9 contain photo documentation of the set-up in the labor-

atory. A schematic diagram of the test set-up in the test stand is shown in annex 10.

3. Measurement and Execution of Measuring

The measurement of the rated sound reduction index Rw in dB of the folding-sliding-system

was carried out in accordance with the requirements of the standard

DIN EN ISO 10140-2

“Laboratory measurement of sound insulation of building elements”

Part 2: “Measurement of airborne sound insulation”

The measurement set-up as well as a description of measuring can be seen in annex 11 of

this test report.

4. Measurement Results

The rated sound reduction index of the setup tested on 23rd

January 2014, installed in func-

tional condition, without any influence from flanking structures was determined as follows:

in annexes 12 and 13.

The measuring results constitute test stand values; a safety margin of 2 dB should be taken

into account for planning applications.

2. Measurement Implementation

For the determination of the airborne sound insulation, electroacoustic generated third octave band noise is

radiated in the transmission room via a dodecahedron loudspeaker. In the frequency range between

50 Hz and 5.000 Hz the margin values generated, are simultaneously measured and recorded in two channels

in the transmission and receiving room, via two condenser microphones in third octave band steps. From

these values and the rev. time, the sound insulation margins, in the individual frequency bands, are deter-

mined according to DIN EN ISO 717. The rated sound reduction index Rw is determined as an individual value,

with the integrated process computer of the sound level analyzer.
