UPGREI

Technical specifications

10 mm-thick acoustic insulation rolls, made of EPDM (Ethylene Propylene Diene Monomer) rubber granules that are anchored with carboxylate latex binder to a backing, made with 80 g/m² non-woven, green-coloured, anti-stretch film and 200 g/m² polyester fibre. Each roll is 500 cm lenght x 104 cm width including a 4 cm adhesive side border for rolls overlapping during installation. The total mass  surface is 2,65 kg/m² and the apparent dynamic stiffness (s’) less than 18 MN/m³.

The Upgrei range is ideal for impact And thermal insulation of all types of floor slabs, especially when high acoustic performances are required.  The extremely resistant yet flexible mat adapts perfectly tot he underlying surface.

  • Very high acoustic and thermal performance
  • Extremely easy to lay
  • Resistant to humidity
