Floor underlayment
CTF PE Foam Sound insulation property: Sound energy can be offset after multiple reflections when the acoustic waves through many foam cells wall. The 5mm thickness foam has the Sound transmission loss of 12dB in the air, 19dB in the floor. The foam is thicker, Sound insulation effect is better.
CTF PE Foam with low water absorption rate and closed cell structure, polyethylene foam has a good waterproof performance, water absorption rate can reach 0.3%, impervious under the condition of 64kpa, 24h.
