Physically branched polyolefin foam with acoustic polyester felt
The Insulit Bi+ 9 is a new acoustic carpet pad against impact and impact noise between floors. This unique and exclusive product has required several years of development and meets the higher acoustic requirements of the latest Belgian NBN S01-400-1 standard. This thin unit of ± 9 mm consists of a very high resistance light-reflecting aluminized film and a double spring structure made of felt + foam, for guaranteed effectiveness. The felt allows correction of low frequencies from 100 to 500 Hz and the foam corrects medium and high frequencies from 500 Hz to 5000 Hz. What is also unique about Insulit Bi+ 9 are the self-adhesive overlaps. They offer easy and reliable placement.
