DB4 Max Acoustic Floor Underlayment

This heavyweight, acoustic floor underlayment is used to block airborne noise and impact sound transmission in commercial and residential spaces. dB4 Max is flexible and versatile and can be used under finished floors including hardwood flooring, carpet, laminate and luxury vinyl tiles thicker than 5mm. dB4 Max is designed with a mass loaded material attached to a polyester fiber layer. The combination of the materials significantly reduces both airborne sounds and structural vibrations including voices, television, music and footfall noises in multi-family units or office buildings. The sound absorption underlayments have received a high IIC rating, indicating dependable impact sound control. Designed with POE (polyolefin Elastomer), this impact noise reduction barrier is a low VOC material. dB4 Max is environmentally safe, does not contain unsafe chemicals and will not harden over time. The high-performance sound barrier layer is puncture-resistant, moisture-resistant and easy to install during the flooring installation process. To install, use the fiber side facing up for nail down hardwood flooring. For all other finish flooring materials including carpeting or ceramic tile use the barrier side facing up.
