DYNAMIC LINE is a resilient underlay made of centrifuged synthetic rubber latex 7 mm thick, black in color, and characterized by a corrugated surface, specifically designed to increase the resilient performance

The product is coated on the side in view with a resistant protective membrane.


  • Impact sound insulation suitable for screeds in sand and cement with reduced content of water thrown directly on the product.
  • Impact sound insulation suitable for applications with radiant floor panels either with sand-cement or self-leveling screeds.
  • Excellent balance between dynamic stiffness, creep and compressibility.
  • Adhesive tape 10 cm wide included in the delivery.


The installation of DYNAMIC LINE must take place without glue, with the grooved surface facing down, and the protection membrane in sight. The resilient underlay flaps should be juxtaposed, with no overlap, and must be sealed using the adhesive tape of 10 cm width included in the delivery of the product. 

Before the DYNAMIC LINE installation you will have to realize the perimeter disconnection with the appropriate FLEXO polyethylene strip, which is to be applied along the perimeter of the room without leaving out the thresholds of the entrances and the doors and windows.

The FLEXO strip must be cut only after laying the finished floor. The whole floor area must be covered by the resilient underlay, leaving no point of contact. In presence of the underfloor heating system, this will only be installed after the impact sound insulation installation. The best performance of the product is obtained with the realization of a splitter screed with a mass of between 100 kg/m2 and 200 kg/m2.
