®ChoVACUSTIC PLUS is a composite mate-rial made of two sheets of polyester laps thermically adhered to a viscoelastic mem-brane.

The combinaison of both materials is resul-ting in an excellent and efficient product to reduce a wide range of frequencies of air-borne sound transmission, and more in par-ticular in masonry walls.

The high density viscoelastic membrane is acting as a sound barrier whereas the pol-yester lap which is a non toxic and recycla-ble material, increases the membrane effi-ciency and transforms the sound energy into thermic energy due to its porous composi-tion.

®ChoVACUSTIC PLUS is presented in rolls of 5.5 x 1 m (Length x Width) and has an overlap of 2 cm.

® ChovAFIX COLA:® 1. Cut a piece of ChovACUSTIC PLUS

adjusted to the size of the partition.®2. Lay the ChovAFIX COLA over the parti-

tion surface by means of a roller .3. Let dry about 3 5 minutes.

®4. Install the ChovACUSTIC PLUS lap of polyester of higher thickness facing up.

5. Repeat steps 1 to 4 and ensure the overlaps of membranes.

6. Seal the joints of the different courses with the adhesive tape to ensure watertigh-tness.

®B) Using mechanical fixings type ChovAFIX :

1. Cut a piece of ChovACUSTIC PLUS adjus-ted to the size of the partition.

®2. Lay the ChovACUSTIC PLUS onto the partition. The layer of the lap with a hig-her thickness facing up.

3. Use a drill of 8 mm to make some holes in the material placed as shown in the sche-me. Perforating speeding should be of 0 .r.p.m

4. Insert the mechanical fixing devices ®(ChoVAFIX 8).

5. Repeat steps 1 to 4 and ensure lap areas of the membranes.

6. Seal the joints of the different courses with the adhesive tape to reinforce watertigh-tness.

STORAGE:Material is to be stored indoor in vertical position.

ChovACUSTIC

® TRIACUSTIC is a composite material made of a polyethylene sheet thermically adhered to a high density viscoelastic mem-brane.

The combinaison of both materials is resul-ting in an excellent an efficient airborne and impact noise insulation acting in a wide range of frequencies.

The high density viscoelastic membrane is a sound damp whereas the polyethylene sheet is reducing impact noises.

The main applications are the acoustic air-borne and impact noise insulation of floor slabs and draining pipes.
