Ravago - Ethafoam 2222 acoustic mat

Ethafoam is a sound-absorbing mat made of extruded polyethylene foam. It has a closed cell structure. It is used to make a layer of acoustic insulation under concrete floors, protecting against transmission of impact sound through the floor structure.

Benefits

• very good acoustic insulation - compliant with European construction standards. Moisture-resistant: Due to its closed cell structure, Ethafoam is resistant to moisture, which allows it to be used in humid environments
• low weight - easy installation
• low thickness: Ethafoam can be successfully used in projects where the height of the floor layer is limited
• longevity - the chemical composition ensures resistance to decomposition caused by the alkaline reaction of the concrete floor (it does not undergo the rotting process)
• durability - high operational durability
• versatility - it can be laid in a single layer or in many layers, depending on the space we have and the intended use
