Multilayer materials for acoustic insulation to low, médium and high frequencies

Data Sheet Certificates Safety Data Sheet Commercial Sheet
DANOFON is a multilayer composite made of a high density bitumen based membrane between two porous textile layers.

Acoustically it works as a low-medium and high frequency insulation.

 Instruction for use

An installation of the DANOFON is shown in the following pictures:

1. Cut the product
2. Placement against wall
3. Clamp with insulation fixing
4. Insulation fixing in the overlap

 Indications and Important Recommendations

- The finishing of plaster on the brick walls must have at least a thickness of 1 cm.

- To cut DANOFON a low rpm manual machine should be used: MAKITA 4191 DW water cooling system or similar, with cutting asphalt disc 85 – 6 MAKITA. ELYWOOD SAW BLADE 3 - 3 / 8” x 15 mm.

- If a battery drilling machine is used (never plugged into the net) the drill bit should be immersed in water to avoid the asphalt from sticking to it.

- Check the product’s technical sheet on safety.

- For further information, please contact our technical staff.
