Project Description

NOVAFLEX AESOUND

Technical Data Sheet

Specifications

NOVAFLEX AESOUND is a low thickness insulating material against impact sound noise designed for acoustic improvement
and the impact sound noise attenuation of existing or new floors by direct gluing under ceramic or wood floors. NOVAFLEX AESOUND is a 750 kg/m3 density, 2,5 mm thickness mat made up

of natural and synthetic elastomeric compound coming from the recycling of end ELT (end of life tyres) and cork granules, bound by mass polymerized polyurethane.

Generic purpose

NOVAFLEX AESOUND is used as a decupling elastic-resilient mat for the creation of floating floors directly under the coating.

Applications

NOVAFLEX AESOUND is used directly under the coating, simply laid in case of floating wooden floor or glued in case of glued wooden floor or concrete floor. The use of the decupling AEFLEX SR band is advisable.
