1 CR. nic so pe Ma Thin section soundproofing membrane to combat the noise of footsteps transmitted through floor slabs, applied before laying ceramic, stone, resilient and multi-layered parquet floors WHERE TO USE M. ay be applied immediately before laying the floor Under-floor soundproofing system applied in a thin coverings. layer to counteract the transmission of noise through floors caused by footsteps. L. ow thickness. Mapesonic CR has been specifically developed W. ith very low emission of volatile organic compounds for application in existing buildings to improve (EMICODE EC1 Plus). soundproofing without removing the floors and screeds. M. ay be applied on heated floors. It is particularly suitable, therefore, for all buildings (residential units, hotels, offices, rest-homes, schools, C. ertified according to current standards. etc.) under renovation. RECOMMENDATIONS. Some application examples O. nly apply on horizontal internal surfaces.

2 Mapesonic CR may be used: D. o not apply in areas subject to heavy traffic. under resilient floor coverings (PVC, rubber, linoleum);. under multi-layered parquet; D. o not apply under lightweight or shiny resilient floor coverings or under cushion-floor. on cement-based substrates;. Apply Mapesonic Strip around the perimeter to on old ceramic and stone floors. avoid the formation of acoustic bridges. TECHNICAL CHARACTERISTICS D. o not expose the material to direct sunlight. Mapesonic CR is manufactured using recomposed cork and rubber bound together with high-quality W. hen applying the product to cementitious substrates polyurethane composite. ensure they are completely cured. ADVANTAGES D. o not apply on floating floors or floors to be polished Efficient reduction of noise from footsteps. in situ. Easy and quick installation.
