Project Description


Technical Data Sheet


AEUREKA 40 is a product were the dialogue between technology, environment and comfort implement itself in the excellence of the result without compromises. Ideal for the creation of habitats where silence, privacy and relax are imperative operative words, AEUREKA 40 is designed for the acoustic insulation either from airborne and from impact sound noises. The product is made of two high density ELT rubber mats (1150 Kg/m3, 18 mm thickness)

coupled with a layer of recycled polyurethane agglomerate (10 mm thickness). The product AEUREKA 40 main characteristic is the high sound insulating power (alone can reach Rw = 40 dB) and its use versatility. AEUREKA 40 is therefore perfect for light structures with extreme needs of acoustic insulation as, for example, the wooden floors, either in case of new constructions and renovations.

Generic purpose

AEUREKA 40 has been created to guarantee high soundproofing performances to light structures with extreme needs of acoustic reduction that, alone, do not have characteristics such as to guarantee the insulating requirements from airborne noise requested by the actual legislation.


Used for light structure insulation such as wooden floors , for which it is rather efficient either for airborne noise insulation and impact sound noise.
