COATED WALL WITH EP 500 AND 700 SUPPORTS + SYLOMER

The new results obtained during the tests carried out by an external laboratory show the multiple advantages of using the EP + Sylomer® wall ties and wall mounts, compared with a conventional masonry wall.

In the new airborne tests carried out by an external laboratory (Itecons - Institute for Research and Technological Development for Construction, Energy, Environment and Sustainability) the results have been compared between a conventional masonry wall and a wall installed with AMC-MECANOCAUCHO® EP + Sylomer® Acoustic Wall Ties and Wall mounts.

The test is performed in a controlled laboratory, in accordance with the ISO 10140-2:2010 standard, by the following procedure:

• Measurement of the sound pressure level in the source room.

• Simultaneous sound pressure level measurement in the receiving room.

• Measurement of the background noise in the receiving room.

For each test the following test specimen has been used, this is composed of a masonry brick wall (bricks with individual dimensions of 300 mm x 200 mm x 150 mm) plastered on both sides (thickness of approximately 15 mm, each side). An acoustical lining on the inner face is constructed with the following elements:

• EP 700 + Sylomer® Wall ties, fixed with bushings and screws to the basic element (air space of approximately 100 mm).

• Metal structure filled with low density mineral wool (nominal thickness of 50 mm) formed by aluminum profiles with thickness of 48 mm and fixed to the EP700 + Sylomer® supports with screws.

• EP 500 + Sylomer® wall mounts under the metal structure.

• One layer of plasterboard with nominal thickness of 12,5 mm and nominal surface mass of 8,0 kg/m² fixed with screws to the metal structure.

• One layer of elastic polymer and minerals with double anti-cracking layer by traction with nominal thickness of 3 mm (ref. “dBimpact Ceracoustic 3.0”).

• One layer of plasterboard with nominal thickness of 15 mm and nominal surface mass of 10,9 kg/m².

• The joints of the plasterboard layers are covered with plaster filler and the layers of plasterboard are peripherally detached from the test rim with acoustic band.

According to the tests results obtained, the wall installed with the EP+Sylomer® Wall Ties and Wall Mounts increases the airborne noise reduction to up to 35dB, compared with the standard masonry wall.
