A mat made of rubber granules, used to improve sound insulation in the event of a very low superstructure height under ceramic cladding. The mats are placed in contact with a thin-layer or liquid mortar on the prepared substrate. The product is also used as a cut-off layer during repairs and in new buildings and in water heating systems.

Features

• smooth surface
• sound attenuation up to 17 dB
• alkali-resistant w
• for service loads up to 3 kN / m ²
• harmless to health
• recycled granulate, bound with elastomer

Application

• stress-relieving layer on fresh, threatened with the formation of shrinkage in concrete surfaces and cracks on screeds or mixed substrates
• Improving thermal insulation on poorly insulated screeds or on bonded screeds
• on poorly insulated floor surfaces
• on substrates that require particularly high acoustic insulation in combination with ceramic and natural stone cladding
• when laying stairs in multi-storey buildings
• cut-off layer especially recommended for critical, fresh substrates prone to the formation of shrinkage cracks
• cut-off layer when repairing old, load-bearing wooden floors (stiff and not deforming) or old ceramic cladding
• a layer that improves thermal insulation during repairs and modernizations and in new buildings
• cut-off layer on screeds in electric and water underfloor heating systems
• in rooms
