Dow - Ethafoam 2222 sound absorbing mat

Ethafoam is a mat made of extruded polyethylene foam with a closed cell structure, designed to provide a layer of sound insulation under concrete floors, protecting against the transmission of sound in an impact by the floor structure. The main benefits are:

• Very good sound insulation - in accordance with European Building Standards. Moisture resistance: due to the closed cell structure, Ethafoam is insensitive to moisture, allowing it to be used in high humidity areas;
• Low weight - easy installation.
• Small thickness: Ethafoam can be successfully used in projects where the height of the floor layer is limited
• Long-term - chemical composition ensures resistance to decomposition caused by the alkaline reaction of the concrete floor (it does not rot)
• Durability - high operational durability
• Versatility - it can be laid in a single layer or multiple layers, depending on the space we have and the intended use.
