• The AnwoollimR technology is designed for thinner floor structures common in apartment remodels while limiting ceiling-height loss.
• Testing by an accredited lab showed the system met new-build legal standards, including Grade 3 for heavy impact noise and Grade 1 for light impact noise, where lower grades indicate quieter performance.
