Heavy Mass Absorbent Layer.
 
The dBA UL EPDM HP is an EPDM based heavy mass sound barrier with an acoustic absorber recycle textile fiber layer. Can be used independently, or incorporated into a multi-layered construction scheme, on walls, ceilings or floors. The absorptive material, increases its efficiency and allows it to be applied directly to air cavities, reducing sound transmission as well as providing sound absorption.
 
Application:
Sound Control Underlayment is used during the installation of timber flooring where the noisetransmission must be reduced and as a subfloor in new and renovation construction projects. Reduces impact noise and vibrations while reducing airborne sound transmission. Acoustic floor underlayment is great under hardwood, ceramic or carpet.
Underlayment soundproofing is largely adopted in public and private sector places such as disco ballrooms, gymnasiums, factory workshops, home cinemas, theaters, concert halls, museums, exhibition halls, library, interrogation room, gallery, auction hall, gymnasium, lecture hall, multipurpose hall, hotel lobby, hospital, shopping mall, school, piano room, conference room, studio, recording room, KTV rooms, bars, industrial plants, etc.
The demand for an acoustic floor underlay in residential living projects is increasing,
the vibrating-absorption acoustic underlayment can hugely reduce noise coming from vibration.
