AIM This report presents the results of the laboratory measurements of airborne sound insulation of 7 Saint Gobain Glazing Partition Systems with tesa ACX plus 7058. The test specimens were selected and delivered by Tesa SE and Saint Gobain Glassolutions. The installation and sealing of the specimens into the test opening was made by Cristalería BELAGUA, S.L. under supervision of personnel of TECNALIA. Each test specimen stayed 24 hours in the same temperature conditions than the test rooms. The tests were performed by personnel of TECNALIA (Construction Area Technological Services Division) in the acoustics facilities of the Laboratory for Quality Control in Buildings of the Basque Country Government, located at Aguirrelanda, Nº 10, 01013 Vitoria Gasteiz (Alava Spain). The details of the test arrangements and test evaluation are described in Annex A. Report Nº B2014 LACUS IN 11 TG B Page 2 of 26 (+ Annex A)

RESULTS For each test sample, the following airborne sound insulation results are featured: Sound reduction index, R, in third octave frequency bands from 100 to 5000 Hz, in table and graph. The Weighted sound reduction index, R w, calculated according to EN ISO 717 1, from the sound reduction index, R. The spectrum adaptation terms between 100 and 3150 Hz, C and C tr, calculated according to EN ISO 717 1, which are the values, expressed in decibels, to be added to the global magnitude value (R w, for example) to consider the characteristics of a particular noise spectrum, such as pink noise (C) and traffic noise (C tr ).

Standard EN ISO 10140 2:2010, together with the other EN ISO 10140 1:2010, EN ISO 10140 3:2010, EN ISO 10140 4:2010 and EN ISO 10140 5:2010, cancels and replaces standard EN ISO 140 3:1994. A.2 Laboratory test facilities The sound insulation tests were performed in the horizontal transmission rooms, composed of a source and a receiving room. The reception room is composed of a double concrete box of twenty and ten centimetres of thickness each one, acoustically disconnected. The horizontal transmission rooms comply with the requirements of the EN ISO 10140 5:2010. A sketch of each room is included in Drawing 1. Annex A to Report Nº B2014 LACUS IN 11 TG B Page 1 of 4

A.4 Test procedures The sound reduction index (R) for the one third octave band 100 Hz to 5 KHz is calculated according to EN ISO 10140 2 standard using the following formula: R=L 1 L 2 +10 Log S/A where, L 1 : Average sound pressure level in the source room. L 2 : Average sound pressure level in the receiving room. S: Test specimen area. A: Equivalent sound absorption area in the receiving room. The measurement of the average sound pressure levels L 1 and L 2 is performed emitting an equalized white noise (between 100 Hz and 5 khz) with a moving omnidirectional sound source. The sound field in the source and receiving rooms is sampled using moving microphone with a sweep radius of 1 m and a traverse period of 16 s during 32 s of measure. Background noise is measured in the receiving room in the one third octave band 100 Hz to 5 khz according to the same measurement process of sound field in the receiving room. The equivalent sound absorption area is evaluated from the reverberation time measured in the receiving room, using Sabine s formula: A=0.16 V/T where, A: Equivalent sound absorption area in the receiving room. T: Reverberation time in the receiving room. V: Receiving room volume. Reverberation time in the receiving room is determined using two positions of the sound source and three fixed microphone positions for each source position, at 120º in the microphone path. Measuring instruments are verified just before and after the execution of the test. Annex A to Report Nº B2014 LACUS IN 11 TG B Page 3 of 4
